Electrical Connections of Inputs and Outputs 

The MCE-22/C has 3 digital inputs, 2 NTC inputs for fluid temperature measurement T and T1 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. 5.5.4) 

 

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

N.B. The inputs can be controlled with any polarity (positive or negative with respect to their earth connection)

 

Table 4: Electrical characteristics of the inputs  

 

The example proposed in

 

Figure 4 

refers to the connection with a dry contact using the internal voltage to control the inputs.

 

 

 

ATTENTION

: The voltage supplied between terminals 11 and 18 of J5 (18-pole terminal board) is 

19 Vdc

 and may distribute maximum 

50 mA

 

If you have a voltage instead of a contact, it can still be used to control the inputs: it will be sufficient 

not

 to use the terV and 

GND  and to connect the source of voltage to the desired input, respecting the characteristics described in 

Table 4. 

 

 

ATTENTION: The pairs of inputs I1/I2 and I3/I4 have one pole in common for each pair.
