Hardware Configuration

The Model 12598-001 Redundant 12 V DC Module consists of a single-sided printed circuit board
measuring 4 L × 4 W × 1.5 H inches (102 × 102 × 38.1 mm). It is equipped with two 15A rated diodes

each mounted t o a heat sink, two s mall DPDT relays to provide dry co ntact sta tus outpu ts for each po w er
supply, and four modular (plug-in type) terminal blocks. All components on the board are through-hole.

Installation

CAUTION

When insta lling or rep lacing this module, be s ure to disconnect power for

safety.

The Model 12598-001 Redundant 12 V DC Module is designed for chassis mounting or on 4-inch Snap
Trak®. When inserting the module in SnapTrak®, exer cise care when pressin g the module edges int o the
SnapTrak

Once installed in the SnapTrak

®

to avoid damage to th e module’s print e d circuit boar d and components .

®

, 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 12598-001 Redundant 12 V DC Module is equipped with modular (plug-in type) terminal
blocks, which simplify external wire connections during installation, and provide quick disconnect if
repla cement is ever required.

The following is a breakdown of each terminal block and its function(s):

TB1 – is the 12 V dc power input from Power Supply 1 (PS1) to the module.
TB2 – is the 12 V dc power input from Power Supply 2 (PS2) to the module.
TB3 – is the 12 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.
