IF51
5.2 Encoder connections with Slave operation
In this mode IF51 converter operates in parallel to another unit, acting as a
„listener“ to the existing data communication.
Quite according to need, the common potential of the master can be connected
to terminal 12 (GND) or remain open for fully differential operation.
5.3 Analogue outputs
The unit provides one +/-10V voltage output and one 0-20 mA / 4-20 mA
current output at a resolution of 14 bits (i.e. the voltage output operates in 1.25
mV steps).
The nominal load of the voltage output is 2 mA; the current output accepts
loads between 0 and 270 Ohms.
A separate analogue ground terminal is internally connected to the GND
potential of the power supply.

5.4 Serial interface
The unit provides both a RS-232 interface and a RS-485 interface, however only
one can be used at a time. Serial communication allows to read out the encoder
position and to set parameters and variables via PC, according to need.
