|1132_0 - 4-20mA Adapter|
- Used to interface 4-20 mA sensors to an Analog Input
- Produces 15 Volts to power sensors
- Can interface sensors with very long wires
- Connects to any device with an Analog Input.
The 4-20mASensors can be connected to and powered by the provided terminals on the 4-20mA Adapter board. The 1132 will measure the current passing through the attached sensor and convert it to a voltage, where it can be displayed as a SensorValue by a Phidget Interface board.
The 4-20 mA Adapter board internally produces +15V from the Phidget InterfaceKit’s input analog voltages which is used to power the connected sensor, eliminating the need for an external power supply.
If the Adapter board is being used in very noisy environments, place a ferrite bead on the sensor current loop close to where it is attached to the 1132.
