WSB2

Warning + Sensor-board wsb2

WITH RS-485 INTERFACE, 4-20 mA OUTPUT AND ALARM RELAY

Simple sensor exchange by plug connection on the local bus.

The warning and sensor-board WSB2 ensures the power supply of the sensors and processes the measured data of the sensor cartridge (SC) for digital communication. Communication with the DGC-06 controller takes place via the RS485 fieldbus interface with DGC-06 protocol. The SC is connected to the local bus via a plug connection.

This allows a simple SC change instead of an on-site calibration. The internal X-Change routine recognizes the exchanged SC during the change process and starts the measuring operation automatically.
