Introduction
The
EXACTUS
®
Industrial Mux (IFM8-IA or IFM8-I) is designed as a data transport device
allowing communication between a host system and up to eight pyrometers. In most situations,
the Industrial Mux can be connected and operate without any setup or configuration changes.
Some of the features that can be configured on Industrial Mux include:
Activation of the analog outputs.
Activation of an instrument monitoring system which detects, and alarms, if any instrument
should fail or otherwise stop communicating.
Configuration of settings which will power down the pyrometer electronics, should their
internal temperature become too high or too low.
Adjustment of pyrometer voltage to compensate for excessive cable resistance.

1. Product Overview
The Industrial Mux (IFM8-IA) communicates with up to 8 Exactus® units. It contains four
interfaces for external equipment: current loop (isolated 0-20mA, 16 bit, 8 channels), RS-485
(isolated, 960K), Ethernet (dual 10/100 Mb/s.), and 2 relays (each NO/COM/NC).
