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 10 module requires ist own supply voltage.
- - X X The module is energised from the SUPREMA Power Supply.
The output terminals 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 module.
- - 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 module.
There is no provision for connecting several contacts in parallel.
S 103
* * - - Contact without a series resistor.
There is no provision for an END OF LINE resistor.
Contact type N.O.:
The number of contacts connected in parallel is unlimited.
A short circuit of the connecting wires will cause a Failure alarm.
