X X - - The Module is connected to an external power supply (18 ... 32 VDC) via terminal
2(+) and terminal 5(-).A Supply Voltage <16 V causes an Failure message.The
out terminals are electrically isolated from the other SUPREMA-terminals.The
maximum allowed Voltage between the output terminals and the other
SUPREMA-terminals is 50 VDC or 24 VAC.Every MSI module requires his own
supply voltage.
- - X X The module is energised from the SUPREMA Power Supply.The output termi-
nals are not electrically isolated from the other SUPREMA-terminals.

X X - - The switch type (N.O.) - Normally OPEN is supported.A closed contact causes
an alarm.Several contacts connected in parallel can be monitored with one mod-
ule.
- - X X The switch type (N.C.) - Normally CLOSED is supported.An open contact causes
an alarm.Several contacts connected in series can be monitored with one mod-
ule.There is no provision for connecting several contacts in parallel.

* * - - Contact without a series resistor.There is no provision for an END OF LINE re-
sistor.
Contact type N.O.:The number of contacts connected in parallel is unlimited.A
short circuit of the connecting wires will cause a alarm.An open circuit of the con-
necting wires is not reported.
Contact type N.C.:The number of contacts connected in series is unlimited.A
short circuit of the connecting wires is not reported.An open circuit of the connect-
ing wires will cause a alarm.
* * - X Contact without a series resistor.END OF LINE resistor = 2.2 kΩ ±5%.
Contact type N.O.:The number of contacts connected in parallel is unlimited.A
short circuit of the connecting wires will cause a alarm.An open circuit of the con-
necting wires will cause a Failure alarm.
Contact type N.C.:The number of contacts connected in series is unlimited.A
short circuit of the connecting wires will cause no alarm.An open circuit of the
connecting wires will cause a alarm.
* * X X Every Contact with a series resistor = 2.2 kΩ ±5%.END OF LINE resistor = 2.2
kΩ ±5%.
Contact type N.O.:The number of contacts connected in parallel is limited
to 20.A short circuit of the connecting wires will cause a Failure message.An
open circuit or interrupt of the connecting wires cause a Failure message.
Contact type N.C.:Only one contact can be monitored.A short circuit of the con-
necting wires will cause a Failure message.A serial connection of that type of
contact can not monitored.
