UI-16 I/O module wiring various signal standards

[robson]

Hi,

I want connect various signal standards to one UI-16 I/O module, for example:

- 4...20 mA (from 2-wire transmitter, with external power source for supply current loop)

- 4...20 mA (from 4-wire transmitter, with active analog output)

- 0...10 V (feedback from actuator, actuator has an independet power supply)

Can I wire, for example, 4...20 mA signal to terminal no 1 and 0...10 V to terminal no 3 (despite the common RET terminal) ?

Can I wire, for another example, 4...20 mA (from 2-wire transmitter, with external power source for supply current loop) to terminal no 1 and 4...20 mA (from 4-wire transmitter, with active analog output) to terminal no 3?

And another question: the manufacter suggests, that system configuration requires a PELV circuit.

Is it necessary in my case?

Can I wire temperature sensor STP 100-250 direct to UI-16?

Are there any special wiring requirements?

you can create your own creativity. These tough economic times force us to innovate.

I guess that you can connect various signals in any configuration to this module within this range:
