4.3.2 Pressure transducers and current probes (4-20 mA)
Two sensors must be connected through one of the inputs (from PB1 to PB2) and the power supply as
shown in the diagram in
Figure 13
below. Refer to
Tables 3 & 10
for the numbering.
The 2-wire sensors require polarity to be respected (+24 VDC power supply).

Connection of the digital inputs
The digital inputs in the PeC controllers can be used as potential free digital inputs.
4.4.1 Opto-insulated digital inputs (24-230 VAC/DC) DI1 and DI4
Refer to diagrams in
Figures 14 & 15
below and to
Tables 3 & 10
for the numbering.
Figure 14: Digital inputs PeC C100
Figure 15: Digital inputs PeC C200
NOTE: For A2L and A3 applications use 24 volts.
4.4.2 Potential free digital input DI2 and DI3
Refer to diagram in
Figure 16
below and to
Tables 3 & 10
for the numbering.
The function is determined by the configuration (currently not in use).
