Technical Specifications

Information About 985A-1CD0-00AA

The 985A-1CD0-00AA is a Watlow Series 985A microprocessor-based temperature controller developed for industrial thermal process regulation. Its construction incorporates a 1/8 DIN panel housing, dual numerical displays, a single thermocouple measurement input, and separate switched DC and electromechanical relay outputs. The controller is designed for integration into compatible heating and cooling systems where an electronic control signal or relay contact is required to operate external equipment. Its programmable temperature control functions support process temperature monitoring and setpoint regulation using the connected thermocouple sensor.

Key Features:

• Series 985A Controller: Industrial digital temperature controller for panel-mounted thermal process applications.

• Thermocouple Input: Single temperature measurement channel with a three-digit display configuration.

• Dual Digital Display: Separate numerical displays provide process temperature and setpoint information.

• Switched DC Output: Non-isolated open-collector output for compatible external control devices.

• Electromechanical Relay: Additional relay output provides electrical switching capability.

• Power Supply: Operates from 115/230 VAC at 50/60 Hz.

• Power Consumption: Rated at 10 VA.

• Panel Mounting: Standard 1/8 DIN format supports installation in industrial control panels.

• Microprocessor-Based Operation: Electronic control circuitry processes temperature measurements and output commands.

• Setpoint Regulation: Supports adjustment and monitoring of the required operating temperature.

• External Equipment Integration: Interfaces with appropriately rated solid-state relays, contactors, and control circuits.

• Industrial Applications: Suitable for compatible ovens, heaters, furnaces, and temperature-controlled machinery.

The 985A-1CD0-00AA delivers the reliability and precision required for industrial temperature regulation, thermal process monitoring, and automated heating equipment control.
