Chromalox 2104-AO100 Digital Temperature Controller Panel Mount Module

Chromalox 2104-AO100 Digital Temperature Controller Panel Mount Module is a microprocessor-based 1/4 DIN temperature and process controller designed for panel mounting in industrial settings. It offers universal sensor input that accepts thermocouples, RTDs, 4-20 mA loops, or 1–5 Vdc signals with a 24 Vdc transmitter power supply, enabling flexible sensor configurations. The front panel provides a clear digital display of the current process temperature and the setpoint for easy monitoring. The controller provides multiple control strategies—PID, ON/OFF, and fuzzy logic—along with one digital input, an analog remote setpoint input, and a 16-segment ramp/soak program for programmable temperature profiles, allowing precise heating or cooling cycles suited to manufacturing or lab environments. Output is a single output drive (relay or SSR) with jumper selection, enabling direct control of heaters or actuators, and the module supports isolated digital communications for interfacing with other controls or host systems. The 2104 family is designed for temperature and process control tasks across applications including temperature, flow, pressure, and level control, making it suitable for heating panels, ovens, process instrumentation, or laboratory reactors. The panel-mount form factor and modular design support easy replacement or integration into existing Chromalox control systems, and the combination of flexible input, programmable ramp/soak, and multiple control modes helps match a wide range of process requirements without needing separate controllers for each variable.
