Relay output count and supply voltage
The Omron E5EC-RX2ASM-800 carries four relay outputs — enough to drive a heater contactor, a cooling fan, an alarm, and a valve positioner without an external I/O block. Supply voltage is 100-240VAC, so it lands directly on a standard control transformer secondary without a separate power supply module.
Sensor compatibility and control method
Accepts RTD and eleven thermocouple types (B, E, J, K, L, N, PLII, R, S, T, U, W) plus 0-20mA and 0-10VDC linear inputs — covers most process sensors without signal conditioners. Control method is On/Off or proportional (PID), so you can tune for tight temperature regulation or simple threshold switching depending on the application.
Panel fit and environmental rating
Panel cutout is 92.00mm x 45.00mm — the standard 1/4 DIN footprint that drops into existing punch patterns without adapter plates. IP66 front panel means it stands up to washdown spray in food or beverage lines; the screw terminals and box packaging keep installation straightforward.
Lifecycle and sourcing posture
Heater fault detection is built in, which saves an external current transformer and alarm relay for monitoring heater element health on packaging or molding machines.
