I/O terminal connector blocks

Pin	Function	Description
Power/Audio
1	Power AC	18 - 30 VAC max 25VA power consumption.
2	Power	18 - 30 VAC max 25VA power consumption.
	AC/DC+	-or-
		22 - 40 VDC max 20W power consumption.
3	GND	Ground
4	Vout	12V/200mA
		Vout can be used to power auxiliary equipment,
		max 200mA.
5	GND	Ground
6	Line OUT	Mono audio output (line level), which can be connected
		to an active speaker with built-in amplifier.
7	GND	Ground
8	Mic/Line IN	Input for a mono microphone or line level mono signal.
Output
1	Out1_1_relay	On the external device output terminals (e.g. Out1_1 and
		Out1_2) there is no distinction between positive and neg-
2	Out1_2_relay
		ative. The terminals use a photocoupler and are electri-
3	Out2_1_relay
		cally isolated from the other internal circuitry.
4	Out2_2_relay
5	Out3_1_relay	The maximum load should not exceed 500mA and the
6	Out3_2_relay	maximum voltage should be not more than 50V DC.
		Note: Connecting AC to the Output will damage the unit.
7	Out4_1_relay
8	Out4_2_relay
Input
1	In1_anode(+)	Electrically isolated from the chassis and connectors,
		these inputs can be supplied from an external DC voltage
2	In1_cathode(-)
		or pin 4 (Vout) of the Power/Audio Connector and GND.
3	In2_anode(+)
		(3.3 - 40VDC allowed on the inputs)
4	In2_cathode(-)
		The terminals use a photocoupler and are electrically iso-
5	In3_anode(+)	lated from the other internal circuitry.
6	In3_cathode(-)
		Note: There is a distinction between anode and cathode
7	In4_anode(+)
		when making connections!
8	In4_cathode(-)
