9.5.1: Overview

The Analog Transducer Signal Output Modules (0±1mA or 4–20mA) are available in either a 4- or
8-channel configuration. Maximum registers per request, read or write, is 17 registers.
Nexus 1250/1252 Unit supplies power for up to two connected Analog Output modules. See
section 9.2 for power and communication details. Refer to sections 5.12 - 5.13 to determine if you
must use an additonal power source, such as the EIG PSIO.
All outputs share a single common point. This is also an isolated connection (from ground).
