Analog Input

Overview

Isolated safety barrier at detection side: PHD-11TD-21, analog input and output, single input and single output.

^ The isolated barrier can isolate and transmit the 4~20mA signal or DC 4 ~ 20 mA signal generated by the transmitter in the dangerous area to the safe area. When the transmitter is two-wire or three-wire system, the safety barrier provides power for the transmitter.

^ This product needs an external 20-35VDC power supply.

^ This product supports HART signal and disconnection alarm.

* Note: If you need other parameters of this product, please contact our technical support. If the output is other parameters, it is indicated by the number 9, and the specific parameters are indicated after the model number.

^ Example: input 2-wire, 3-wire or 4-20mA, output 2~10V.

^ Model: PHD-11TD-29 (2-10V)

* Bus power supply, see appendix for details.
