What it is and what it does
The Omron CRT1-OD08TA-1 is an output module in the CRT1 series, providing 8 solid state outputs for connection to CJ, CS, and NJ series PLCs via the CompoNet remote I/O network. It mounts on a DIN rail and terminates through a rectangular connector and screw terminals. Solid state outputs mean no mechanical wear and faster switching than relay outputs, suitable for inductive loads or high-cycle applications within the module's rated current and voltage limits.
Where it fits
The module is sized for Omron's CRT1 remote I/O racks and communicates over the CompoNet network. It is explicitly listed for use with CJ, CS, and NJ series controllers, so no adapter or additional gateway is needed if the PLC already supports CompoNet. Operating temperature range of -10°C to 55°C covers most industrial cabinet environments; verify ambient cooling stays within this range if the panel is densely packed.
Sourcing and lifecycle
The module carries CE and cULus approvals.
