Description

The EL5101-0090 EtherCAT Terminal allows direct connection of incremental encoders with differential inputs (RS422). A 32/16 bit counter with a quadrature decoder and a 32/16 bit latch for the zero pulse can be read, set or enabled. Interval or frequency measurement are possible. The gate input allows the counter to be halted. The counter state is taken over with a rising edge at the latch input.
