Universal Systems US-977CA Temperature Controller

The Universal Systems US-977CA Temperature Controller is a microprocessor-based PID controller with Auto-Learn that maintains bath and process temperatures with precision in wet benches, chemical processing equipment, plating systems, and other industrial bath applications. Operating at 120 VAC, 50/60 Hz, it uses a Type J thermocouple for temperature sensing, and it features a digital LED display, PID control with Anti-Reset Windup and Auto-Learn, multiple status and alarm outputs, and an integrated process timer for timed operations. This panel-mounted 977 Series device is designed for semiconductor and industrial environments to monitor and regulate bath temperatures, helping improve process stability and reliability. Common replacements include Omron E5CC Digital Temperature Controller, Fuji Electric PXE4 PID Temperature Controller, and Watlow EZ-ZONE PM Temperature Controller.
