2 Channel Analog Inputs 0-20 mA / 4-20 mA
(Differential Inputs)
PN 750-452, 454, 750-482, 750-484
Technical Description
This description is only intended for hardware version X X X X 2 A 0 0 - - - -. The serial number can be found on the right side of the module.
The input channels are differential inputs and they have a common ground potential. The inputs are connected to +I and -I. The shield is connected to „S“. The connection is made automatically when snapped onto the DIN rail.
These I/O modules are not provided with integrated power jumper contacts. The power supply is made by the data contacts with a DC-DC converter. The modules can work self-supporting.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)! A module which needs all contacts (e.g. 2 channel digital) may not be connected to the right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel modules).
The input module can be connected to all buscouplers of the :$*2Ç, 2Ç6<67(0 (except for the economy type)

The numerical format for Siemens
In addition to the full 16 bit indication of the measured value it is possible to use the ‘Siemens format’. The measured value is represented by the most significant 12 Bits. The 3 least significant Bits are reserved for diagnostic and status purposes. (750-482, 484)
