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.

BENEFITS

• Digital processing of measured values incl. temperature compensation

• Internal function monitoring with integrated hardware watchdog

• Up to 3 different sensor cartridges (2 identical SC2 possible)

• Analog input, 4-20 mA for an analog sensor

• Software according to SIL2 compliant development process

• Modular technology (pluggable and exchangeable), IP65 design

• Easy maintenance and calibration by replacing the sensor cartridge or by convenient on-site calibration

• Serial RS-485 interface with protocol for DGC-06 (optional Modbus)

• 4-20 mA analog output

• 1 alarm relay with changeover contact, potential-free max. 30 V AC/DC, 0.5 A

• 1 fault signal relay, additionally configurable as alarm relay, with changeover contact, potential-free max. 40 V AC/DC, 0.5 A

• Display (optional)
