PID controller LIBRATHERM INSTRUMENTS

Libratherm offers Micro-controller based universal input/output PID controller model PID-966 (version 1.2). The features are incorporated, taking into consideration all types of process control applications, where such PID controller is required to be used. The model accepts all widely used industrial inputs, such as standard types of thermocouple, RTD(Pt-100), and 4-20mA/0-10Volt signals. The desired type of input is user selectable through front panel key board in combination with the back panel DIP switch.

All standard control outputs are available to control variety of end controlling devices. The switching PID output of 0 to 10 VDC pulse can be used to control Relay, Contactor, Solid state relay or AC/DC solenoid valves (Suitable isolated interfacing cards are also available). The analogue PID control outputs are user configurable for (0-20)mA, (4-20)mA, (0-5)VDC or (0-10)VDC. The control action can also be configured through front panel key board as per requirement, such as direct control or reverse control, or both direct and reverse control or ON/OFF control. Two extra relay outputs are also provided as high and low alarm. The analogue outputs can also be configured as retransmission output, proportional and linearized to the selected input signal. Serial interface is available on 2 wire RS485 with MODBUS RTU protocol in slave mode, with the programmable modbus address - so that it can be directly interfaced to DCS or PLC.
