Barber-Colman A11844 Temperature Control Card

The Barber-Colman A11844 Temperature Control Card is an analog input module for the MACO process control system that processes temperature sensor signals (thermocouples, RTDs, or other analog inputs) and provides the control interface to regulate process temperature. Operating via analog PID-based control (system dependent), it generates control signals for relays or external drivers to maintain the setpoint in automated industrial processes. The unit is rack-mounted in an industrial control chassis, powered by the system backplane, and features industrial-grade signal isolation suitable for installation in control cabinets. Common applications include ovens, furnaces, plastics processing equipment, and injection molding machines—manufacturing systems that require reliable closed-loop temperature control.
