7.3 CONNECTION OF THE ANALOGUE INPUTS
The analogue inputs in the programmable controllers and expansions are fully configurable. NTC or PTC, 0 -
20mA, 4 - 20mA, 0 - 10V, 0 - 1V or 0 - 5V type of sensors can be used.
The analogue inputs can also be used as digital inputs (potential free - not live).
NOTE: Any devices that require 24Vac/dc power supply must be powered separately with another
transformer.
7.3.1 Temperature probes (NTC and PTC)
2-row sensors that do not require polarity to be respected.
Each sensor must be connected through one of the inputs (from Pb1 to Pb10) and the common (PbC) as
shown in the diagram below.
IPG-IPC IPG-IPC 4 DIN
Recommendations:
- follow the diagram of the device used, for the numbering.
- the configuration is determined by the application.
- if used as a digital input (potential free - not live), use the same connection configuration of the sensors.
7.3.2 Pressure transducers and current probes (0 - 20mA, 4 - 20mA)
2-row sensors that require +12Vdc power supply.
Each sensor must be connected through one of the inputs (from Pb1 to Pb10) and the power supply (+12V)
as shown in the diagram below.
IPG-IPC IPG-IPC 4 DIN
Recommendations:
- follow the diagram of the device used, for the numbering.
- the configuration is determined by the application.
