The input module 2x pulse/analogue

22.4.1 Function and connections

The module has two universal inputs e.g. for flow, temperature or pressure sensors with the following
output signals:
• Pulse transmitters of different types, incl. classes IB, IC, ID, IE according to EN 1434
• Frequency signals 0 ... 10 kHz
• Analogue current signals 0 or 4 – 20 mA
Each of the two input signals is connected via a 3-pole plug-in terminal.
Active and passive transmitters must be connected differently:
Active transmitters are transmitters with their own power supply
Passive transmitters are transmitters that are powered by the module
The integrated output power supply is short-circuit-proof and can be loaded with 25mA per output.
The module recognises an overload of the power supply.
The inputs are not galvanically isolated, i.e. they possess a common ground for active
transmitters. Observe polarity! Do not connect negative voltages!
