DSE157
Output Relay Expansion Module
The DSE157 is an output relay expansion module designed for use with the DSE 52xx, 53xx and 55xx control modules.
The module includes eight configurable relay contacts (energised/de-energised) that enable Original Equipment Manufacturers (OEMs) to achieve greater output flexibility to meet complex industry generator control specifications.

Specification
DC SUPPLY
The DSE157 is powered from the plant battery or from a low voltage supply between 8V and 35V continuous. It is able to survive 0V for 50ms during cranking, providing supply was at least 10V before dropout and supply recovers to 5V. This is achieved without the need for internal batteries.MAXIMUM OPERATING CURRENT
120mA @ 12V, 70mA @ 24V
MAXIMUM STANDBY CURRENT
25mA @ 12V, 18mA @ 24V
AUXILIARY RELAY CONTACTS
5Amp DC rated voltage free
SELECTOR SWITCHES
Test - Operates all relays to test operation.Unused - No function.
Enable Lamp Test - Relays will energise on receipt of a lamp test signal from host module.
A/B Select - Determines whether the DSE157 responds to signals for expansion A or B relays.
INDICATIONS
Lit LED - Power OnFlashing LED - Link lost (to controller)
