Electrical input protection
The input circuit is protected against voltage-reversed polarity, voltage transients, surges,
and spikes, according to EN50270.
Electrical outputs
•
0-20 mA current output: The 0-20 mA is an isolated sink option. You can also configure
this output as source (see
The maximum permitted load resistance is 500 Ω.

Wiring
This protocol is standard and widely used.
It enables continuous communication between a single standard Modbus controller
(master device) and a serial network of up to 247 detectors.
It enables connection between different types of Rosemount detectors or other
Modbus devices to the same network.
