Compatible Sockets:
This relay is designed to plug into standard RH series 8-pin relay sockets (e.g., SH2B-05, PF083A, or equivalent – not included). Ensure the socket matches the pin configuration before installation.
Installation Guidance:
Disconnect all power to the control panel before handling.
Mount a compatible 8-pin relay socket to DIN rail or panel.
Wire the socket according to your circuit diagram (terminals correspond to relay pins).
Plug the relay firmly into the socket until fully seated.
Restore power and verify proper operation.
Important Compatibility Note:
This relay requires a separate 8-pin socket for installation. Verify that your existing socket or planned socket is compatible with the RH2B-ULAC24V pin layout. This is an aftermarket replacement part engineered to meet OEM specifications for the RH series.
Package Includes:
2 x RH2B-ULAC24V Power Relays
Safety Disclaimer:
Installation should be performed by qualified personnel following all applicable electrical codes and safety regulations. Always disconnect power before servicing relay or control circuits.
