EJ1N
Multi loop in-panel temperature controller
EJ1N is designed to deliver an easy-to-use Multi-Point Control System able to optimize wiring job and space saving thanks to its modular approach
- Reduce Crossover Wiring with Horizontal Connection Structure
Simply connect power supply line and RS485 to end unit module to power up the entire system - Available with screw terminals and screw-less clamp terminals
- Fit in your machine configuration perfectly
Up to 64 module (2 loops and/or 4 loops version) can be installed on the same communication RS485 line - All major sensors input type supported (thermocouple, Pt100, linear)
- Simplify commissioning tasks thanks to extensive set of feature to make PID tuning effort easier
2-PID algorithm to achieve both good step response and disturbance response, Independent Autotuning for heating/cooling PID control, disturbance overshoot adjustment function for temperature fluctuation rejection.
