The hardware features a 3-wire single-ended connection technology, which simplifies wiring for active current loops. A critical engineering advantage of this terminal is the integrated watchdog function; in the event of a fieldbus communication interruption, the output can be configured to a predefined safety value or follow a specific ramp, preventing unpredictable mechanical behavior. The internal process image utilizes a 1 x 16-bit AO output format, allowing for straightforward mapping within TwinCAT or other EtherCAT masters.
