4.4. Analogue Inputs
The differential inputs on the input side of the converter accept standard voltages (± 10 V),
standard currents (0/4 - 20 mA) and also potentiometer connection. The drawings below
explain the principle of the input circuits with each of the input connection modes.

4.5. Incremental Outputs
A complete set of incremental channels A, /A, B, /B, Z and /Z is available for incremental
representation of the analogue input signal. Inverted channels are for optional use and may
remain unconnected if not needed (e.g. for transmission at a 24 volts impulse level with use of
channels A and B only). Likewise also the marker pulse outputs Z and /Z may remain open
when the application does not provide zero pulse evaluation.
Dependent on the respective Mode of Operation of the converter the incremental output signals
represent either a frequency proportional to the analogue input signal (i.e. straight analogue-to-
frequency conversion), or a linear or angular position (i.e. for applications with analogue linear
scales or analogue angular transducers).
All output lines are equipped with push-pull drivers (short-circuit-proof) and the output swing
(signal level) results from the remote voltage applied to terminal X
3
[8].
Upon non-connection of
this terminal the unit automatically generates a 4 volts TTL-compatible output.
