3.6 Sensor supply connection
Connect the sensor supply at terminals 12 and 13 – for example en-
coder supply, etc.
Do not use the sensor supply to supply non-earthed inductive or
capacitive loads. The sensor supply is short-circuit proof (exception
model 24/48 VAC).
Voltage supply Sensor supply Current load
24 VAC 10...26 VDC 60 mA
48 VAC 10...26 VDC 60 mA
85...265 VAC 24 VDC ±20 % 100 mA
12...30 VDC 9...28 VDC ±20 % 100 mA
3.7 RS485 interface connection
The serial interface can perform the following functions:
- retrieve data
- program parameters
Interface parameters are:
- transmission speed (baud rate),
- parity bit,
- number of stop bits,
- address of controller for master.
