Failsafe Alarm Relay Specifications; Supported Networking Standards; Operating Environment - Siemens SIMATIC NET RUGGEDCOM RST2228P Installation Manual

Voltage Range
a
The required wire size depends on the number of POE modules installed in the system and the
maximum current capability of the POE power source. Each POE module will draw up to 3A maximum
with a system maximum of 12A. Follow applicable local wiring codes and standards for minimum wire
gage.
