3-27 7.1 95-8533
ENHANCED DISCRETE INPUT/
OUTPUT (EDIO) MODULE
INSTALLATION
All electrical connections are made to the field wiring
connectors furnished with the module. Refer to Figure
3-25 for identification of module wiring terminals.
Connector P1, Terminals 1 to 6
24 vdc Power Input
Connect the module power supply to terminals 1 and
2. If additional terminals are required for powering
other devices, these devices should be connected to
terminals 4 and 5. Shields are to be connected to
terminals 3 and 6 — chassis (earth) ground terminals.
Terminals are rated for 10 amperes. Use both sets of
input terminals in parallel if total output current can
exceed 10 amperes.
Connector P2, Terminals 1 to 6
LON/SLC Signaling Circuit Terminals
Be sure to observe polarity when wiring the LON/SLC.
1 — "A" side of signaling circuit for COM 1
2 — "B" side of signaling circuit for COM 1
4 — "A" side of signaling circuit for COM 2
5 — "B" side of signaling circuit for COM 2
3, 6 — shield connection
Connector P3, Terminals 1 to 12
Terminals A,B & C
Channels 1 to 4 Input / Output Terminals
Refer to individual wiring configurations for terminal
descriptions. Only channel 1 is shown in each
diagram. The information is typical for channels 2-8.
