Selection & installation notes
- Select AC or DC output to match the load; verify operating voltage, thermal derating and surge capacity for the exact relay. Output markings are not a complete application rating.
- The source compares the form factor with RJ1S and G2R-1-S. Verify pinout and socket compatibility before replacement; isolate all power before inserting or removing a relay.
- RT-GK dimensions and interface options apply to assembled modules, not bare GK relays. Confirm the module, fuse and terminal combination when ordering.
