– 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
– 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-
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:
“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 ).
In the event of interruption of auxiliary voltage, all auxiliary voltages
(and thus all sensors) are switched off!
– 4 terminal pairs for the connection of 4 differential signal lines or
break contact/make contact type devices (only connect passive
components)
– 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.
– 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
– 2 terminal pairs for the connection of UPS switching outputs
– Potential-free, digital
– UIN +5 V…+25 V
– IIN maximum 5 mA
– RJ45 modular jack for connection to a 10 Mbit Ethernet
