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
