Wiring PLC I/O

All interface devices must accommodate active true low logic for correct operation with
AFC1500 SAN Unit inputs and outputs (I/O).

Optional Field bus interface is available when using a Multi Unit.

Outputs are rated at 12~24 VDC, 200mA.
Open collector sink outputs pull the input device signal low (0 VDC) when activated.

Inputs are normally high and activated when pulled low (0 VDC).

SAN2 (25 pin) I/O connection

SAN3 (34 pin) I/O connection

Mating connector: Honda MR-25M

Mating connector: Honda MR-34M

FIG. 4-7-1 San Unit PLC Connector

Note: If you are adapting from an older SAN 25pin cable connector to a new SAN3 34 pin con-
troller, use cable adapter FEB-1522. This will allow the use of your old 25 pin I/O cable for
use with a new SAN3 Controller unit.

CAUTION:

The PLC I/O wiring must be routed a minimum of 300 mm away from
any transient high voltage sources. Cable length must not exceed 50 feet.

DO NOT connect a positive DC voltage source to the output common.
