The AR-100 provides a 25 pin connector for control interface. This is labeled “Cont. B” on the unit. Below is a list of the pin assignments wired to Cont. B for interface with external control devices:

The pin numbers start from right to left 1-13 on first row and 14-25 on the second row. To supply power from an external power supply unit (DC power), use the Control Input and DC Input Terminal (CONT A) or the Control I/O Connector (CONT B) DC in and GND pins.

Power supply specifications: DC +9-24 V, 450 mA. The DC OUT pin of the Control I/O Connector (CONT B) can be used as power supply for a sensor, etc.

Caution: For safety reasons, do not connect the DC IN + pin of the Control Input and DC Input Terminal (CONT A) to metal parts such as the chassis or the Control I/O Connector (CONT B).
