The modules provide high precision and simple, high-resistance measurement from 300 mV to 300 V. Using the digital multimeter terminals with fieldbus interface for measuring current and voltage, measured values can be processed directly in the I/O system or by the master controller. Terminals are available for both the Beckhoff Bus Terminal system, which offers support for most major fieldbuses as well as for the high performance EtherCAT® Terminal system.
