This module can be used to determine paths and to calculate speeds at the same time. The ultrasonic transducer rods are connected directly to the RS422 interface.
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.
The CX9020 is a compact, DIN rail-mountable Ethernet control system with 1 GHz ARM Cortex™-A8 CPU. The connection for the Beckhoff I/O systems is directly integrated into the CPU module.
