Wiring Connections and Cabling
Configuration of the termination unit is required to accept the
digital field inputs sent to the DSI module. Refer to
for additional information.
Physical Installation
The DSI module inserts into a standard module mounting unit
and occupies one slot. To install:
1. Verify the slot assignment of the module.
Disconnect power before installing dipshunts on the module
WARNING mounting unit backplane. Failure to do so will result in contact
with cabinet areas that could cause severe or fatal shock.
2. Verify that a dipshunt is in the I/O expander bus socket on
the module mounting unit backplane between the I/O module
and controller.
3. For termination units, connect the hooded end of the ter-
mination cable from the termination unit to the module
mounting unit backplane. To do this, insert the connector into
the backplane slot in the same slot as the one assigned to the
DSI module. The latches should snap securely into place.
4. Align the DSI module with the guide rails in the module
mounting unit. Gently slide the module in until the front panel
is flush with the top and bottom of the module mounting unit
frame and the module is seated in the cable to the termination
unit.
5. Push and turn the two captive retaining screws on the
module faceplate one half turn to the latched position. It is
latched when the slots on the screws are vertical and the open
ends face the center of the module.
Wiring Connections and Cabling
The DSI module has three card edge connectors to supply logic
power, establish I/O expander bus communication and pro-
vide digital inputs (P1, P2, P3 respectively).
