Information About SD3C-HCJA-AARG
The SD3C-HCJA-AARG is a Series SD controller with dual red/green displays and a standard overlay carrying the Watlow and SD logos. Its configurable input accommodates supported thermocouples, RTDs, and analog process signals for integration with different measurement devices. The primary output supplies a DC switching signal for compatible external switching hardware, while the secondary output provides a normally open mechanical relay contact. This configuration operates from 100–240 VAC and excludes the optional Modbus and infrared communication interfaces.
Key Features:
- PID Regulation: Controls a measured process variable against the selected setpoint.
- Selectable Control Action: Supports heating or cooling with PID and on/off operating modes.
- Universal Input: Accepts compatible temperature sensors and analog process signals.
- Switched DC Output: Provides Output 1 for commanding a compatible external power-switching device.
- Mechanical Relay Output: Includes a 2 A Form A normally open relay at Output 2.
- Dual-Color Displays: Uses red and green readouts for process values, setpoints, and operating parameters.
- Compact Panel Mounting: Fits a 1/32 DIN opening for installations with limited panel space.
- Local Configuration: Provides front-panel access to settings without requiring a network connection.
The SD3C-HCJA-AARG delivers the reliability and precision required for single-loop temperature regulation in industrial machinery and thermal processing equipment.
