What it is and what it does
The Omron E5CC-TRX3A5M-006 is a panel-mount temperature and process controller from the E5CC-T series. It accepts RTD, thermocouples (Types B, E, J, K, L, N, PLII, R, S, T, U, W), and analog signals (0–20 mA or 0–10 VDC) across a −200°C to 2300°C range. Control is On/Off or proportional (PID) with four relay outputs.
What the ratings mean for fit
This controller provides four relay outputs and accepts 100-240 VAC supply. Panel cutout is 45.00 mm x 45.00 mm; the controller mounts flush with an IP66 seal for washdown environments. Screw terminals are provided for connection.
How it compares to nearby siblings
The E5CC-CX3A5M-004 swaps one relay for an analog output and adds RS-485 communications. The E5CC-RX3A5M-003 keeps four relays but adds heater fault detection and RS-485. Both siblings carry a serial port for CompoWay/F or Modbus; this seed has no comms. If your BOM requires a network connection, you need one of those alternate MPNs.
Sourcing and lifecycle reality
For a BOM freeze, the E5CC-CX3A5M-004 or E5CC-RX3A5M-003 are the closest functional alternatives if you later need communications, but they require a wiring change for the different output configuration.
