PPT245 Multifunction Indicator/Controller

Brand: Calex Electronics Limited

The PPT245 DIN-rail mounted controller provides a highly versatile alternative to panel-mounted instruments. 

It has one Analog input which is configurable for up to 18 different sensors/signals, two relay outputs, and a third output which can be configured either as a SSR logic signal or a 4-20 mA /0-10 V Analog signal for control or re-scalable retransmission of the process variable or setpoint.
Features
  • Fully configurable indicating PID controller for single control loop
  • DIN rail or wall mount
  • Universal Analog input for current, voltage, thermocouple, RTD, thermistor, potentiometer, or loop break alarm via current transformer
  • Ideal for measurement of temperature, pressure, flow, level, pH, and many other process values
  • Rescalable Analog output for control, retransmission or signal conversion
  • Relay and SSR outputs
  • Provides temperature indication and emissivity adjustment for PyroEpsilon infrared temperature sensor
