Electrical Connections of Inputs and Outputs
The MCE-22/C has 2 digital inputs, an analogue input and 2 digital outputs so as to be able to make certain
interfaces with more complex installations.
Shown in
Figure 4, Figure 5
and
Figure 6
for example, are some possible configurations of the inputs and
outputs.
For the installer it will be sufficient to wire up the desired input and output contacts and to configure their
functions as desired (see par. 5.5.1 par. 5.5.2 and par. 5.5.3)
5.5.1 Digital
Inputs
The digital inputs are screen-printed at the base of the 18-pole terminal board:
-
I1: Terminals 16 and 17
-
I2: Terminals 15 and 16
-
I3: Terminals 13 and 14
-
I4: Terminals 12 and 13
The inputs may be powered with either direct or alternating current. Shown below are the electrical
characteristics of the inputs (see
Table 4
)
