Description
On the external device output terminals (A and B), there is no distinction
between positive and negative (+ and -). The terminals use a photocou-
pler and are electrically isolated from the other internal circuitry.
The maximum load should not exceed 100mA and the maximum voltage
should be not more than 50V DC. Note: Connecting AC to the output will
damage the unit.
Photocoupled Input 1. Electrically isolated from the chassis and connec-
tors, this input can be supplied from an external DC voltage or the DC
Power Input/Output on pins 9 (DC+) and 10 (GND).
Photocoupled Input 2. As above.
A half-duplex RS-485 interface for controlling auxiliary equipment.
This can drive the photocoupler inputs or other equipment. The output
voltage level is 3.0 V. A maximum current of 100mA can be sourced from
the DC output.
Ground.
