The Omron E5EC-RR2ASM-828 is a current-production digital temperature controller with a universal input that accepts thermocouple, RTD, or analog signals. It fires two relay outputs—handy for heating and cooling zones or alarm-plus-control—and powers up on any 100-240 VAC line, which means no fiddling with voltage taps when you swap it into a panel built for a different region. Screw terminals keep the install simple: strip, torque, go. No crimper, no special tool. If you're pulling a dead controller off a machine and need a drop-in candidate that's still on the distributor shelf, this one fits. Active lifecycle means you're not chasing surplus or NOS—just quote and order. The dual relay config (RR) gives you independent control channels, each with its own relay, so one unit can manage both a heater and a contactor without an external slave.

Frequently asked questions
What input type does the E5EC-RR2ASM-828 accept?
It uses a universal input (M type) that accepts thermocouples, RTDs, and other analog signals common in process loops.
What power supply voltage does the E5EC-RR2ASM-828 require?
The controller runs on 100 to 240 VAC, covering global line voltages without a conversion transformer.
