DC Solid State Relay Board (Compact)

DC Solid State Relay Board: This is an opto-Transistor with optical isolation between an input signal and output signal. This is to be used for switching 24V-60VDC supply by 5V-230 VDC input signal.

Features

  • DIN rail mountable, compact and easy for troubleshooting
  • Two/Four/Eight phototransistors on a single board
  • Sink or Source type input connectable
  • LED indication for input signal
  • Ideal to drive hydraulic and pneumatic solenoid coils
  • Built-in freewheeling diode across driving load for every individual output point

Technical specifications

  • Input signal voltage: 3 VDC-100 VDC, Typical voltage is 24/10/5VDC
  • Max. input current: 20 mA @24VDC
  • Max. output voltage: 60 VDC
  • Min.output voltage: Supply voltage-4 VDC
  • Max. load per output point: 5 Amps
  • Peak non repeatitive surge current: 8 Amps
  • Input to output electrical isolation: 3.55 KV
  • Max. Voltage drop in output voltage: 2.5 V @ 2 Amp load
  • Switching ON/OFF delay: 10 microseconds
  • Load type: Resistive and Inductive
  • Size: 40X90 (2 POINTS), 70x90 (4 points), 90x140 (8 points)

Applications

a) For switching contactors from PLC outputs
b) For switching DC loads like solenoid valves, DC actuators, DC Lamps, DC electromagnets in industrial use directly from controller outputs
c) In all applications where we need very fast switching and require isolation between a driver and driven circuits. The load can be inductive or resistive

Solid State Relay Board Vs Relay Board Comparison

Sr.No. Solid State Relay Board Relay Board
1 Switching Time 10micro sec Switch On time 18 ms & Switch Off time 18 ms
2 No limitation on number of operation at 5 Amp load 300,000 operations is limit at 2A/230V load
3 Max load 5 Amp per point Max. load 5/10A per point
4 To be used for DC Switching Can use for AC/DC Switching

Standards/Approvals

CE certified

PCB:IEC 61373

Optoisolator/transistor:UL/VDE

Connectors:CE, Profile and end plates:UL

Availability

Available in 2/4/8 points variants.

Solid State Relay boards with input signal other than 24/10/5 VDC can be supplied on demand.

Caution: DO NOT USE SSR BOARD FOR SWITCHING AC SUPPLY!
NOTE:- Due to continuous product development the product supplied to you may look different than the product image in the pdf file.
