Hardware Architecture and Relay Construction

The IC693MDL940L contains six miniature sealed relays on a single PCB. Each relay features a form C contact set with common, NO, and NC terminals. Sealed construction prevents dust and moisture contamination. Six green LEDs illuminate when the corresponding relay coil energizes.

Interface and Connectivity

One 20-position removable terminal block connects relay contacts to field wiring. Each channel provides three terminals (C, NO, NC) for flexible wiring. A 24-pin backplane interface receives control commands from the CPU. The module requires no external power supply for relay coils.

Practical Installation Notes

Install this output module in any I/O slot of a Series 90-30 rack. The IC693MDL940L can switch mixed AC and DC loads on different relays. Always use an external fuse or breaker for load protection. Verify the contact current does not exceed 2A per relay for long life.
