Description
The CRM-93H/UNI is a multifunction time relay designed for universal use across automation, industrial control, regulation, and building/house installations. It offers a universal supply voltage range (AC/DC 12–240 V), making it a flexible choice for panels where a single relay needs to work across multiple supply voltages without ordering separate variants.
Function and time-range selection is done conveniently via rotary switches, with 10 selectable timing functions and a wide time range from 0.1 seconds up to 10 days across 10 sub-ranges. A multifunction red LED indicates operating status, flashing or shining depending on the active state, giving installers a quick visual check without needing to open a panel door. The relay provides one SPDT output contact rated 16 A plus two additional DPDT contacts rated 8 A each, and its control input (S) allows a load (such as a contactor) to be connected directly between S and A2 without interrupting correct relay operation — a space- and wiring-saving feature for control panel builders.
