DIGITAL IN			– 8 terminal groups (of 4 terminals) for connecting 'break contact/make
			contact' type devices, or devices with switching output
			– Potential-free, digital
			– Left terminal pair “IN+” AND “IN-” digital input
	IN+	+12V	– For the connection of a break contact/make contact, an auxiliary vol-
			tage of +12 V (top terminal) and an earth reference GND (bottom ter-
	IN	GND	minal) can be connected from the right terminal pair using the enclosed
			cable links (see connection examples below).

	– UIN +5 V…+25 V
	– IIN maximum 5 mA
	– With auxiliary +12 V supply, maximum current draw of 200 mA
	– Auxiliary voltage interruption in connection with overload or short cir-
	cuit in the sensor cable:
	Enter
06 12S Overload	“Fault” LED lights up.
	Confirm the "overload" message in the LCD display using the ENTER key,
	then switch back on in the menu “Aux.Volt.” with the ENTER key (> 6 ).

Note	In the event of interruption of auxiliary voltage, all auxiliary voltages
	(and thus all sensors) are switched off!

ALERT IN		{
				– 4 terminal pairs for the connection of 4 differential signal lines or
	RMS			break contact/make contact type devices (only connect passive
				components)
	LITE
				– Maximum drawable alarm current approximately 20 mA
				– For differential signal lines, ensure that the closed-circuit current of
				the entire signal line does not exceed a total of 900 µA.
TEMPERATURE/HUMIDITY				– 4 RJ11 modular jacks for the connection only of the Infratecplus sen-
				sors available in the delivery programme (temperature sensor, humidity
				sensor or combined temperature/humidity sensor)
				– digital
UPS IN			{	– 2 terminal pairs for the connection of UPS switching outputs
	RMS			– Potential-free, digital
				– U +5 V…+25 V
