Omron E5AN-HAA2H Digital Temperature Controller

The Omron E5AN-HAA2H Digital Temperature Controller is a panel-mounted, 1/4 DIN PID controller designed for industrial temperature regulation in control panels, ovens, and process equipment, with universal input support for thermocouples, RTDs, voltage, or current sensors. It operates on 100–240 V AC, provides 1-loop control with outputs that can be relay, voltage pulse, or current/linear (model dependent), and features a high-resolution display with 0.01°C resolution, about 60 ms sampling time, and IP66 front-panel protection. The unit is part of Omron's E5AN-H series (model E5AN-HAA2H), with panel mounting dimensions of 96 × 96 mm (1/4 DIN) and communications options RS-232 / RS-485 / RS-422 (model dependent). Common replacements include E5AN-HAA2HBM-500, E5EN-HAA2HBM-500, and E5CC-RX2ASM-802, and its applications span plastic molding, packaging equipment, furnaces, and HVAC systems for industrial temperature monitoring and precise control.
