Bacharach MGS SERIES Installation Guide

1: OPERATING AREA AND CONDITIONS
The Bacharach MGS Series controllers provide local
alarm status indicaons (via mul-colored, per-
channel LEDs) as well as common single-level or
dual-level digital (relay) alarm outputs based on 1, 2,
4, or 6 input signals and 1 or 2 user-definable
set-points.
MGS Controllers support mulple input sensors/
transmiers (1, 2, 4, or 6 channels) based on the
model of the controller. Inputs are standard 4-20 mA
signals from MGS-series sensors or any standard,
linear, 4-20 mA transmier.
The instrument is powered 100V-230V AC (50-60Hz) or
12V DC (specified at me of order).
