Analog Input Modules

(T3420A, AF)

Industrial Control Services

transmitters (that require loop power) you will typically need

to connect a 24 VDC power source in the input loop to power

the transmitter and the input loop.

In fault tolerant input applications where redundant analog

input modules interface to single sensors, the analog input

signals connect in parallel across the redundant input

modules. In current input configurations, the three modules

connect in parallel across the single external 250 Ohm

resistor.
