Field Wiring Guidelines

Overview

This section contains wiring guidelines and precautions for wiring the 170AMM11030 Momentum I/O base.

Terminal Connector

To connect field devices to the I/O base, you need a field wiring terminal connector. Schneider Electric sells terminal connectors in sets of three.

Type	Part Number
Screw-in	170 XTS 001 00
Spring-clip	170 XTS 002 00

Busbar May Be Required

Depending on the type of field devices you are using, you may need a 1-, 2-, or 3- row busbar. The following busbars are available from Schneider Electric.

Type	Number of Rows	Part Number
Screw-in	1 - row	170 XTS 006 01
	2 - row	170 XTS 005 01
	3 - row	170 XTS 004 01
Spring-clip	1 - row	170 XTS 007 01
	2 - row	170 XTS 008 01
	3 - row	170 XTS 003 01

Mapping Terminal Blocks and Busbars

The following table shows the mapping of terminal blocks and optional busbars.

Row #	Terminal #	Connection	Function
2	1-8	01 ... 08	Discrete outputs 1-8
	9-10	AI1, AI2	Analog inputs 1-2
	11 & 13	AO1+, AO2+	Analog outputs 1-2
	12 & 14	AO1-, AO2-	Return for analog outputs 1-2
	15	AGND	Return for analog inputs
	16		Return for discrete outputs
	17		Return for outputs
	18		+DC power for outputs
3	1-16	I1 ... I16	Discrete inputs 1-16
	17		Return
	18		+DC power
4	1-18	PE	Earth ground for field devices, PE analog ground
