DC Solid State Relay – Wiring Diagram

[DOWNLOAD PDF]

This diagram shows how to wire the DC Solid State Relays to your system. Your system may come with 1 or more relays. In this example, a two relay box is used as an illustration. The other relays should be wired in a similar fashion. The diagram assumes customer supplied voltage of 24VDC but it can go up to 60VDC.

Note: These relays are NOT “dry contact” relays. They will not “short” at the output. They are designed for switching DC voltages only.

SCALE SIDE (SETPOINT ACTUATOR) (J1)
3V3 –Common voltage from Scale (Sink Configuration)
1S –Setpoint Input 1 (Actuator for Relay #
2S –Setpoint Input 2 (Actuator for Relay #2, if connected)
GND –Scale Ground Reference.
[DO NOT MODIFY WIRING ON THIS SIDE]

LOAD SIDE (RELAY CONTROLLED OUTPUT) (J2)
+VE –Customer Sourced Power (Max 60VDC)
1A –Output from Relay 1
2A –Output from Relay 2, if connected
Output from Relay 2, if connected…GND –Supply Ground
