DC Output Modules
GEK-83521B
July, 1989
General Description
The discrete (OFF/ON), 8-point DC Output module
can be utilized in an I/O rack, or in any of the I/O
slots in a Model 60 Central Processor Unit (CPU), to
provide an optically isolated interface between the
backplane I/O bus and user output devices. The first
four outputs are grouped to share a common power
source, as are the second four outputs. The module for
each output-voltage range is available in either a
source or a sink version. The DC Output modules’
features and benefits are summarized in Table 1.
When using a sink module, current must flow through
the load into the output terminal of the module. When
Each of the eight output drivers uses a Darlington
amplifier as a switching device. The circuit board also
contains comparator circuitry that determines if the
module is being addressed and a buffer where the
output data is stored and presented to the output
drivers.
Provision is made to automatically disable the entire
group of output drivers in the event of an I/O-chain,
or CPU, failure. Light-Emitting Diode (LED) indicators display the state (ON/OFF) of each output, and
the condition of the individual output-circuit fuses.
Refer to Table
specifications.

Installation
The DC Output module can be installed in an I/O rack
or in a model 60 CPU rack. Before installing the
module, set the Dual-In-Line-Package (DIP) switches
directly behind the card slot on the rack backplane to
establish the proper correspondence between the output terminals on this module and a group of eight
consecutive output numbers in the program. To determine the proper switch settings, refer to the table in
the Installation section of the Series Six Installation
and Maintenance Manual, GEK-25361.
We recommend that he extraction/insertion tool furnished with the CPU be used to remove or install the
circuit board. With the board in place in the rack, the
faceplate should be slipped over the circuit board so
that the terminals near the bottom of each are mated.
The faceplate can then be secured to the rack using
the thumbscrews at top and bottom.
Refer to Figure 2 for typical user connections to the
DC Output module. One side of each load controlled
by this module should be connected to the appropriate
output terminal (1 through 8). The other side of each
load connected to terminals 1 through 4 should be
returned to a common line connected to the Neutral
No.1 (N1) terminal for a source module, or to the
High No.1 (Hl) terminal for a sink module. The
other side of each load connected to terminals 5

through 8 should be returned to a common line connected to the Neutral No.2 (N2) terminal for a source
module, or to the High No.2 (H2) terminal for a sink
module. A user DC power source must be connected
between the Hl (+) and the Nl (-) terminals; a power
source must also be connected between the H2 (+)
and the N2 (-) terminals. Each terminal can accommodate one No.12 AWG wire or two No.14 AWG
wires. The terminal cover should be installed by
_---r--t-I
guiding both of its edges onto the top of the terminal
block and sliding it downward over the terminals.
Note that a markable area is provided on the plastic
lens beside each pair of indicators for noting the function or destination of each output. The faceplates are
color coded (blue) to allow you to easily distinguish
the DC Output modules from other types of I/O
modules.
