Dual-Output Process Controller with Event Input and Heater Fault Detection
This Omron E5CC-TQX3A5M-001 is a panel-mount process/temperature controller from the E5CC-T series, accepting inputs from RTD and a wide range of thermocouple types (B, E, J, K, L, N, PLII, R, S, T, U, W) as well as 0–20 mA or 0–10 VDC analog signals. It offers both relay (3) and voltage (external SSR) output types, giving flexibility for driving contactors or solid-state relays directly. The dual-color LCD backlit display shows two rows of four characters each, with 0.600" and 0.280" character heights for process value and setpoint. IP66 rating makes it suitable for washdown or dusty environments if properly gasketed. Built-in event input and heater fault detection expand monitoring capability without an additional logic module. Control method supports On/Off or proportional PID with auto-tuning expected from the series family. Mounting fits a standard 45×45 mm panel cutout with screw terminals accepting 100–240 VAC supply. Rated for –10°C to 55°C ambient operation.
Peer Comparison: E5CC-CX3A5M-004 — What Changes
The frequently cross-shopped E5CC-CX3A5M-004 shares the same form factor, panel cutout, and screw terminals, but carries two functional differences: it replaces the relay+voltage output with an analog output and includes RS-485 communications (CompoWay/F, Modbus). It also lacks heater fault detection, though it retains event input. If your BOM requires heater fault detection or the ability to switch loads via relay/SSR without an analog output, the -TQX3A5M-001 is the correct choice. The -CX3A5M-004 works where a proportional analog signal and digital communication to a PLC are needed. Physical swap is possible but electrical re-termination is required.
