GENERAL DESCRIPTION
The Gould B356-001, 24 VDC Output Module
J converts logic signals used within the
Micro 84 Programmable Controller into
eight independent 24 VDC outputs. Logic
format for the module is “true high”. Each
output is capable of driving relays, pilot
lamps, motor starters, solenoids, or other
loads up to 2.0 Amperes. The module uses
eight transistor switches to control loads
connected to an external power source.
These switches are designed to withstand
the high surge currents typical of industrial
loads.
Each output is electrically isolated from the
controller by an optical coupler. This
enables the module and controller to with-
stand the severe voltage transients
prevalent in an industrial environment. Both
IEEE and ANSI standards for surge withs-
tand capability (SWC) tests are fully
satisfied.
The output circuits are divided into two
groups of four outputs each. Each group is
r, driven by a separate voltage source. An
LED indicator connected to each circuit’s
field side displays the ON/OFF status of
the output. The LED indicates the output’s
true state.
The module is housed in a light weight,
durable LEXAN case. A structural
“chimney” within the module provides flow-
through convection cooling and protection
from moisture build-up. Self-contained
mounting brackets eliminate the need for
special I/O housings. A termination con-
nector is shipped with the Micro 84 main-
frame to be used when the module is at-
tached to the extreme right bus location.
User connections are made to a standard
screw terminal strip. This strip is compati-
ble with an optional Fanning Strip (P/N
0212-012) which allows quick module
replacement without disturbing field wiring.
Data bus connections are made with stan-
dard interface connectors. These connec-
tors allow the B356 Output Module to be
placed in any location in the l/O structure
without interfering with other module
operations.
