2157 Output Expansion Installation Instructions
Introduction
DSE2157 relay expansion module is used in conjunction with the DSE7000 series controllers to
provide additional relay output functionality. The relay outputs are configured in the ‘host controller’,
the DSE2157 module is not itself configured apart from the ‘ID switch’ detailed below.
For further details on configuring the ‘host controller’ you are referred to the relevant configuration
software manual.
Controls and indications
LED Indications
Function Colour Action
Power on / Link lost RED Steady when DC supply is connected and data is being received
from the host controller.
Flashing when the DC supply is connected and the data
connection to the host controller is not operating.
Status 1-8 RED Lit when the corresponding relay is active
ID switch
The rotary ID switch is used to select the ‘ID’ of the 2157 expansion module as the host controller is
capable of giving instructions to a number of 2157 expansion modules at the same time (consult
relevant modules instructions for further details on number of supported expansion units).
The enclosure cover must be unclipped and removed to gain access to the switch. The switch should
be operated using a small screwdriver and set to match the required ID.
NOTE : The ID must be a unique number, different from the ID of any other 2157 module
connected to the host controller.
If two or more 2157 controllers are required to ‘mimic’ each other then they should be
configured with different IDs, and both configured the same in the host controller.
NOTE : The selection of the ID of other types of expansion modules WILL NOT interfere/clash
with the ID of the 2548. For instance if the 2548 is set to ID 4, it is acceptable to have a different
type of expansion module (for instance 2130) set to ID 4 also.
