Replacing an IMASI13 Module

Introduction

User Differences

Thermocouple, Millivolt
or Milliamp Inputs
WBPEEUI240774A0
The IMASI13 module and the IMASI23 module are similar. The
minimal differences are discussed in this section.
The only user differences between the IMASI23 and the
IMASI13 is the input configuration jumper blocks J1-J16. The
IMASI13 has 4 pin jumper blocks, where the IMASI23 has 6
pin jumper blocks. Refer to Figures
tional jumper pins in the IMASI23 allow the Input(-) to be con-
nected to that input's isolated common COM, which is required
for proper operation of open thermocouple detection on the
IMASI23. Refer to

An installation using an IMASI13 module may have jumpers
added between the minus (-) and the C terminals in the NTAI06
Termination Unit for thermocouple inputs. When replacing the
IMASI13 module with an IMASI23, the jumpers on the Termi-
