Input
– Output
(via software MSCom2)
The firmware can manage up to 32 digital inputs and 20 output relays; among these, 4 digital inputs and
6 output relays are available on the relay module, the remaining are available on additional expansion
modules controlled via the CAN-Bus communication channel.
Can be controlled 1 or 2 additional modules.

(see wiring diagram) are shorted.

Four Digital Input are available on main relay:
D1
(0.D1)
(terminals 38 - 28)
:
Programmable
D2
(0.D2)
(terminals 38 - 18)
:
Programmable
D3
(0.D3)
(terminals 38 - 29)
:
Programmable
D4
(0.D4)
(terminals 38 - 19)
:
Programmable (PTC)
Three of them (0.D1, 0.D2, 0.D3) are disactivated, when the relevant terminals are open and get
activated when the relevant terminals are shorted by an external cold contact.
The operation of the Input “0.D4” is dependent on the value “R” of resistance of the external circuit
connected to its terminals (38-19):
-
Activated if “R < 50
” or “R > 3000
”. - Disactivated if “50
R
3000
”.
Therefore, if the terminals “38-19” are open-circuited, the input “0.D4” is activated; for using “0.D4” as a
normal Digital Input simply controlled by an external cold contact, it is necessary to permanently connect
across the terminal’s “38-19” (in parallel to the external contact) a load resistor of value between 50 and
3000
(example 1000
- 0.5W).
The additional inputs “1.D1....1.D15” are available when the first expansion module is present.
The additional inputs “2.D1....2.D15” are available when the second expansion module is present.
Any digital input of the expansion modules is active when the relevant terminals (see wiring diagram) are
shorted.
