Reliance Electric S-67107-1 Solid State Relay

Reliance Electric S-67107-1 is an OEM input module for Reliance Electric PLC systems, designed to accept digital signals from field devices and feed them into the controller's logic program. The variant S-67107-1A is linked to the 57C419 5-24 VDC INPUT MODULE, confirming the family’s operation on a 5 to 24-volt direct-current input range and its role in converting external sensor or switch outputs into PLC-friendly logic levels. Used in legacy industrial automation, this module interfaces sensors and automation equipment with the PLC I/O bus, supporting standard 5–24 V DC sensing devices and helping define reliable, centralized control logic within a broader Reliance Electric automation platform. When sourcing this part, buyers typically encounter it in surplus or replacement-part catalogs for older Reliance Electric installations, where it serves to expand or retrofit digital input capability on existing PLC hardware.
