Omron CRT1-TS04P is an active analog input module from the CRT1 series, packing four analog channels for CJ, CS, and NJ controller families.
Mounts on DIN rail, terminations through a rectangular connector and screw terminals. The four analog channels share a common ground; plan for separate shielded cabling per channel if the signal leads run alongside power wiring. Operating range covers most industrial bay temperatures, but keep the module away from direct heat sources if ambient peaks above 55°C.
