Finder 34 Series:  Slim P.C.B. Relays (EMR or SSR) 0.1-2-6A

Finder’s Solid State Relays are excellent in interfacing applications.  Small SSR’s such as Finder’s 34 Series draw only a few mA, so they sip at the limited output currents available from PLCs.

 

The 34 Series (EMR) relays include the following features (according to Type):
• Sensitive DC coil: 170 mW
• 5 mm wide – 6kV (1.2/50 μs) isolation, coil – contacts

The 34 Series (SSR) relays include the following features (according to Type):
• Sensitive DC input circuits
• 5 mm wide
• Silent, high speed switching with long electrical life

 

Applications:
• Bottling Plants
• Packaging Machines
• Labelling Machines
• Road / Tunnel Lighting
• Burners, Boilers & Furnaces
• Timers & Lighting Controls
• Electronic Circuit Boards
• Programmable Controllers

Finder 77 Series Solid State Relays

Finder.jpg

Modular solid state relays (SSR) 5 – 15 – 30A

 

A solid state relay is ideal when fast, frequent switching is required. For example, precision temperature control of an industrial oven might require switching off the mains supply to the heating elements every two or three seconds. Finder’s 77 Series would be the best component to operate this with input AC or DC, 230 V AC or 400 V AC output and rated voltage range (19…305) V AC or (48…480) V AC and is most suited to heater controls.

The 77 Series is made up of modular and “hocky puck” style solid state relays with the folowing features (according to Type):

 

 

 

Function and Features:
Input AC or DC
• 230 V AC or 400 V AC output
• Rated voltage range (19…305) V AC or (48…480) V AC
• Zero-crossing and random switch-on versions
• Suitable for lamp loads
• 17.5 and 22.5 mm housing
• Features (“hockey puck”)

Input AC or DC
• 230 V AC or 400 V AC output
• Switching voltage range (19…305) V AC or (48…480) V AC
• Suggested applications: heater control
• Mounting to heatsink with screws
• Zero-crossing version

Applications:
• Drying Kilns
• Heating & Cooling
• Lighting Control
• Bottling Plant
• Labelling Machines
• Packaging Machines

Crouzet SSR Smart Series Application

crouzet1

Smart Solid State Relays detect compressors load failures

An ultra-low temperature (ULT) freezer is a refrigerator that stores contents at between −40 to −86 °C (−40 to −123 °F), usually dedicated to life science applications such as new generation vaccine storage. ULT freezers are commonly fitted with alarm systems that will remotely alert designated parties in the case of a freezer failure.

UL Approved*  D Size Form C (Changeover) Relay

•  100W switching power.
•  Changeover contacts.
•  PCB Mount.
•  Available with or without a magnetic screen.
•  Tungsten contacts for high power switching.
•  Large package size.
•  Up to 4A carry current.
•  Often used in applications which require circuit protection or circuit breakers.

The D1 series is a reed relay with changeover contacts which are often used in safety critical applications.

The switching is achieved through the use of high vacuum reed switches with Tungsten contacts and make these relays suitable for high reliability applications, such as test equipment and high voltage power supplies.

These are PCB mount relays, though custom options may be available on request.

*Consult factory for UL ratings:
These products have been UL approved for use as per pollution degree 2 classification.

S Size Form C (Changeover) Reed Relay

• Compact footprint.
• Changeover contacts.
• PCB Mount.
• Available with or without magnetic screen.
• Up to 3W switching power.
• Up to 1.2A carry current.
• Small package size with compact footprint.
• Rhodium contacts for low contact resistance and high durability.
• Often used in applications which require circuit protection or circuit breakers.

The S3 series is a compact reed relay with changeover contacts which are often used for safety critical applications.

Low contact resistance, through the use of Rhodium contact reed switches, makes the S series suitable for many high voltage applications at DC and low frequency, where performance and reliability are paramount.

These are PCB mount relays, though custom options may be available on request.
