The input and output channels of the Bus Terminal have a common ground potential. The run LEDs give an indication of the data exchange with the Bus Coupler.
The device connected to the terminal communicates with the automation device via the Bus Coupler. The active communication channel operates independently of the higher-level bus system in full duplex mode at up to 115.2 kbaud. The RS232 interface guarantees high immunity to interference through electrically isolated signals.
This module works with both 4-wire and 6-wire strain gauge load cells. The concept applied by the module requires compensation in the measurement system. This compensation eliminates the absolute uncertainty in the measurement circuit, such as component tolerances, effective bridge voltage or zero point offset.
The module is a digital output module that is equipped with 4 opto-triac outputs using phase-angle control. L and N are fed to the module for zero-crossing detection.
