General Information
The Model 12598-004 Redundant 48 V DC Module is designed to accept the outputs of two 48 V dc
power supplies while providing a single dc output. This module will typically be used in custom
products, namely ADVANCE cabinets requiring redundant circuits to meet various agency requirements.

Hardware Configuration
The Model 12598-004 Redundant 48 V dc Module consists of a single-sided printed circuit board
measuring 4.0 L 4.0 W 1.5 H inches (102 102 38.1 mm). It is equipped with two 15A rated
diodes each mounted to a heat sink, two small DPDT relays to provide dry contact status outputs for each
power supply, and four modular (plug-in type) terminal blocks.
Installation
CAUTION
When installing or replacing this module, be sure to disconnect power for
safety.
The Model 12598-004 Module is designed for chassis mounting or on 4-inch Snap Trak
inserting the module in SnapTrak
, exercise care when pressing the module edges into the SnapTrak to
. When
avoid damage to the module’s printed circuit board and components.
Once installed in the SnapTrak
, be sure the module edges are secured in the channels so that the module
does not dislodge during transport or operation if subjected to vibration. Also, if this module is used with
other modules in the SnapTrak
, be sure to leave spacing between modules to facilitate wiring at any
edge-mounted terminal blocks.
Terminations
The Model 12598-004 Redundant 48 V dc Module is equipped with modular (plug-in type) terminal
blocks, which simplify external wire connections during installation, and provide quick disconnect if
replacement is ever require d.
The following is a breakdown of each terminal block and its function(s):
TB1 – is the 48 V dc power input from Power Supply 1 (PS1) to the module.
TB2 – is the 48 V dc power input from Power Supply 2 (PS2) to the module.
TB3 – is the 48 V dc power output from the module to the load.
TB4 – are dry output contacts for the PS1 and PS2 faults respectively. Each connected power supply has
two sets of contacts, which are a Form “C” type. The maximum switching capacity for each contact set is
30 V dc @ 1 amp, and can be used for triggering a remote status indicator or a supervised input at a
system device for visual text display.
