Whatever your application, the easyE4 control relay allows for control systems that are efficient, flexible and easy to implement. The new easyE4 range is significantly more compact than the previous easy500, easy700 and easy800 series.

Thanks to the flexible expansion with up to 11 modules to a maximum of 188 inputs/outputs, as well as the large voltage range, the easyE4 is ideally suited for industrial and building applications. For additional flexibility, the intuitive easySoft programming software comes with four programming languages as standard, including function block diagram (FBD) and structured text (ST). New helpful function blocks, such as the automatic e-mail notification, as well as the possibility of creating own function blocks facilitate the programming for each user.

Thanks to the integrated web server, both mobile devices or an HMI can be used for visualization purposes. If used in combination with other products from the Eaton portfolio, the easyE4 can also be integrated into IIoT (Industrial Internet of Things) system architectures via the integrated Ethernet interface. In combination with the interrupt function, the powerful processor enables faster processing and response times during operation.

• Maximum flexibility, with up to 11 local expansion modules per base unit
• The 188 available inputs/outputs within a single easyE4 system provide coverage for a broad range of applications
• A compact product with a large voltage range (DC, AC and UC)
• Base units with different voltage types can be combined as required by means of the available expansion modules, which makes handling the easyE4 devices extremely easy

Crydom announces a new addition to the NOVA22 product family, the PMP Series of panel mounted proportional control SSRs.

With ratings of up to 90 Amps @ 40°C these fully configurable relays are perfect for applications that require to control the amount of power delivered to a resistive load in proportion to an analog control input.

PMP Series are fully configurable Panel Mount proportional control relays with micro controller based technology designed to provide control of the power delivered to single-phase loads of up to 90 Amps at 90 to 600 VAC.

PMP Series SSRs vary the output power in proportion to an analog control input, which can be one of 3 signal types: 0-5 VDC, 0-10 VDC or 4-20 mA. The output can be controlled by 2 different methods, selectable on the unit: Phase Angle Control, and Burst Fire Control (with Distributive Zero Cross).

PMP Series proportional controllers are ideal for a wide range of applications that require control of the load power, such as for example lamp dimming and resistive heating control.

Main features of the PMP Series include:
-  Output ratings of 25, 50 and 90 Amps
-  Available in 3 operating voltage ranges: 90-280, 345-530 and 420-660 VAC
-  Selectable Operation Mode: Phase Angle or Burst Fire control
-  Selectable Control Input: 0-5 VDC, 0-10 VDC, 4-20 mA
-  50/60 Hz Adaptive Operational Frequency function
-  4-20 mA input does not require an auxiliary power supply
-  LED multifunction status indicator
-  Contactor configuration with "Elevator" screw terminals
-  Optional overvoltage protection (built-in TVS diode)

Crydom is pleased to announce the expansion of their SOLICON DRC Series, now featuring new DRC3P 3-phase contactors with higher operating voltage rated at 600 VAC and an enhanced 18-30 VDC control input option for DRC3R Reversing models.

DRC Series
•  7.6 Amp AC Semiconductor Motor Controller
•  Load voltage range up to 600VAC
•  Fits standard 35mm DIN Rail
•  LED input status indicator
•  AC or DC control
•  Zero Voltage (resistive loads) or instantaneous (inductive loads) turn-on output
•  C-UL-US Listed, CCC Certified, IEC Rated, CE & RoHS Compliant, Horsepower Rated
•  Built-in Overvoltage Protection
•  Ultra-efficient thermal management design (Patented)

Solicon DRC3 Series are Solid State Contactors intended for frequently switching on and off three phase loads up to 5 HP, 600 VAC 7.6 Amps. They are available in both contactor versions
DRC3P and reversing contactor versions DRC3R.

The Solicon Contactor DRC3P is available in either instantaneous turn-on (for Motor Control) or zero voltage turn-on (for Resistive Loads). It is available in either 2 or 3 controlled leg versions. The 2 legs control version is particularly suitable for motor control circuits where the neutral conductor is not utilized.

The Solicon Reversing Contactor DRC3R includes an interlock control that allows only off, forward and reverse operation in a safe mode while providing high space saving; it switches
instantaneously upon application of the control voltage unless an instantaneous change of direction is commanded, then it will delay the direction change by 100msec in order to prevent
simultaneous forward and reverse operations.

All the models of Solicon DRC3 Series combine the benefits and advantages of a solid state contactor with the functionality and simplicity of use of an electromechanical contactor thanks to the proprietary thermal management technology (Patented) and complete electrical insulation (no grounding required); the embedded auxiliary contacts, normally open and/or normally
closed, are intended to be used at 18-280VAC. Five different control voltages are available in order to cover most applications. All models include overvoltage protection.

DRML1, Crydom’s Load Monitoring Module designed to detect partial or total load failure
 of up to 8 loads and 50 Amps

Crydom introduces the DRML1 Load Monitoring Module, specially designed for NOVA22 solid-state relays which allows to monitor up to 8 heating elements, with similar current value, for a total current ranging from 1.2 Amps up to 50 Amps.

The DRML1 module measures the current value and compares it against a pre-set value (Teach value), which is stored during installation. Normal operation is monitored and failures are detected. An alarm is activated when the module detects undercurrents in the heating circuit below -12.5% of the nominal current. The module allows also for other alarm conditions to be detected such as: overcurrent condition (when the current exceeds the maximum of +12.5% of the nominal current), blown fuses (open load), damaged (short circuited SCR) and interrupted SSR, as well as those in half-wave operation. The nominal current value (Teach value) is set by the operator either with the "Teach-In" push button, placed on the front, or with the external “Teach-In” input.

The new DRML1 Load Monitoring Module offers three unique features in the market. It allows the user to select the maximum current value of 20 Amps or 50 Amps, operates with a minimum partial load detectable value of 150 mA and includes an adjustable alarm response delay (0.1 sec, 1 sec or 5 sec), selectable via a parameter selector switch. This avoids fault messages generated by voltage drops.

Malfunctions are indicated by a multicolor LED and can be localized systematically thanks to the alarm output which allows up to 128 DRML1 modules to be connected to a collective alarm. The LED indicates when power is ON and also when the Teach-In function is activated (Blue), when the input signal is ON (Green) and when an alarm condition is activated (Red).

The DRML1 is designed for direct installation on NOVA22 Solid State Relays contactor configuration versions (both Panel Mount PM22 Series and DIN Rail Mount DR22 Series models). The plastic enclosure provides IP20 level protection.

DRML1 can be used in different applications but its key advantages make it ideal for quality supervision of plastic parts production in injection molding machines, thermoforming machines and rubber parts production.

Main features include:
-  Up to 8 loads can be monitored
-  Selectable max current rating: 20 Amps or 50 Amps
-  Selectable alarm delay (0.1 sec, 1 sec, 5 sec)
-  Minimum current for single load: 150 mA
-  Alarms detected: undercurrent, overcurrent, open mains voltage, SSR fault
-  Alarm output: PNP open collector, 6-28 VDC, 100 mA
-  Up to 128 modules can be connected in parallel
-  Operating temperature: -25°C to +70°C
-  Pluggable module for both DIN Rail and Panel Mount NOVA22 SSRs
-  Multicolor LED with input status and alarm indication

Crydom’s DRML1 Module is C-UL-US Recognized and compliant to IEC 61000-4 (EMC) and IEC 60068-2 (Shock and Vibration) requirements. It’s also CE compliant to the Low Voltage Directive as well as the RoHS Directive.
