The GIMATIC CH102-G is a compact, programmable temperature regulator designed for industrial heating and cooling control. Featuring an LCD display, auto-tuning PID algorithm, and dual-output configuration, it provides precise temperature management for plastics machinery, rubber processing, packaging equipment, and other industrial automation applications. The 48×48 mm panel-mount form factor fits standard DIN cut-outs, and the optional RS-485 communication enables integration into plant-wide monitoring systems.

Auto-Tuning PID Control with Dual Output

• Auto-Tuning PID Algorithm: The CH102-G features a self-adjusting PID algorithm that automatically determines optimal control parameters during commissioning. This reduces setup time and ensures stable temperature regulation even under changing thermal load conditions. The controller continuously monitors the process temperature and adjusts the PID constants as needed, eliminating the need for manual retuning.
• Heating and Cooling Control: The dual-output configuration allows independent control of heating (OUT1) and cooling (OUT2) circuits from a single unit. This is particularly valuable in applications where both heating and cooling elements are used—the controller automatically switches between heating and cooling modes to maintain the setpoint temperature, eliminating the need for two separate controllers.

Universal Input and Configurable Alarms

• Thermocouple Input Compatibility: The CH102-G accepts a wide range of thermocouple types (K, J, E, S, etc.), enabling a single controller model to be used across multiple applications without hardware modifications. The input type and temperature range are configurable through the front panel or via digital communication.
• Configurable Alarm Modes: The controller supports multiple alarm configurations including high deviation, low deviation, high/low deviation, band alarm, and absolute value alarms. Each alarm can be independently assigned to the alarm output (ALM1), providing flexible process monitoring and safety protection.

Compact Design and Communication Options

• 48×48 mm Panel-Mount Housing: The compact 1/16 DIN form factor (48×48 mm front panel, 45×45 mm cut-out) allows the CH102-G to fit into standard panel openings. This makes it suitable for retrofitting existing equipment and for new installations where control panel space is limited.
• Optional RS-485 Communication: Models equipped with RS-485 support digital communication for remote monitoring, setpoint adjustment, and data logging from a PLC, SCADA, or PC-based management system. The protocol supports multi-drop configurations, enabling a single communication bus to connect multiple controllers.
• 230 V AC Power Supply: The controller operates directly from standard industrial mains voltage, simplifying wiring and eliminating the need for a separate power supply unit.
