Dwyer Series 4G Temperature/Process Loop Controllers allow for monitoring and control of temperature or process conditions. The controller features two independent control outputs for dual loop control using on/off, auto-tune or self-tune PID, fuzzy logic, or manual control methods. RS-485 interface is included with Modbus® communication protocol, for easy bench-top configuration or integration with a PLC or data control system.

Features:

• On/off, PID, Fuzzy Logic, or Manual Output Control


• Constant, Sloped, Program (Ramp/Soak), or Remote Set-Point Control


• 2 Primary Control Outputs, 2 Secondary/Alarm Relay Outputs, and RS-485 Standard on All Models


• Options for Remote Set-Point, Input Retransmission Available with Optional Hardware
