Connecon of quarter bridge or PT1000 with M12 version
The following graphic shows the connec of a quarter bridge for the M12 version. The
bridge extension should be adapted depending on the applican.
Adaptaon of the bridge extension for BSC4D
Opening the device
1. Remove both screw covers from the input side and remove the fastening screws from the front
cover.
2. The two hexagonal bolts on the 37-pin D-Sub port must be loosened using a socket
spanner (5 mm).
3. The printed circuit board is pulled out on the side of the 25-pin D-Sub port.
Adaptaon of the bridge extension with M12 version
The bridge extension can be individually adapted for each channel, for this purpose the device must
be opened and, according to the following gures 1 - 5, the desired soldering bridge must be added.
For PT1000 probes, the addinal resistance 1kOhm is selected.
Please set the solder bridges:
• HB1 when using channel 1
with a quarter bridge.
• HB2 when using channel 2
with a quarter bridge.
• HB3 when using channel 3
with a quarter bridge.
• HB4 when using channel 4
with a quarter bridge.

Wiring diagram for posi sensors
The measuring ampli BSC4D must be congured by the manufacturer separately when using it
with potenometric posiensors (linear potenmeters or draw wire displacement sensors)
for the M12 version.
The posi sensor’s wiper is connected to the measuring amplir’s “Aux” input (M12) or “UE“ (37-
pin D-Sub). The posi sensor supplies via the sensor supply +Us and -Us.
5-pin port 37-pin D-SUB port
The potenometric posi sensor is supplied with 2.5 V. The
“Aux” input or UErecords voltages of 0...5 V.
