The Omron E5EC-RR4A5M-009 is a process and temperature controller from the E5EC series, accepting inputs from RTDs and a wide range of thermocouples (B, E, J, K, L, N, PLII, R, S, T, U, W). It operates on 100–240 VAC, providing six relay outputs and RS-485 communication (CompoWay/F or Modbus). The controller is rated IP66 for dust-tight, water-resistant panel mounting and fits a rectangular cutout of 92.00 mm × 45.00 mm.
Panel mount into a 92.00 mm × 45.00 mm cutout with screw terminals for wiring and RS-485 (CompoWay/F or Modbus) communication. The tri-color LCD displays three rows of 4 characters each. Control methods include on/off and PID. The event input can trigger alarm reset, run/hold, or remote setpoint selection — useful for sequences where a PLC handshake is needed.
