Quatech INTERBUS S manual Channel Analog Inputs +/- 10 V Differential Inputs, AnalogInputs

2 Channel Analog Inputs +/- 10 V (Differential Inputs)

PN 750-456, 750-456/000-001

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)￿
