Compact and cost-effective analysis of incremental signals

Four new, powerful EtherCAT Terminals complement the product range

Incremental encoders have become indispensable in many applications – often they are small and inexpensive. Beckhoff have extended the EL51xx terminal series for analysis of 5 V incremental encoders with RS422 and TTL signals with the aim of implementing incremental signal analysis within the control system in a space-saving and cost-reducing manner.

Four new, highly compact products complement the existing portfolio, based on the latest technology. Each EtherCAT Terminal features an integrated sensor supply that can be parameterized for 5 V, 12 V or 24 V and offers compatibility with RS422, 5 V TTL and open collector encoders. Based on internal pull-up resistors, no external wiring is required for open collector analysis. Additional 24 V digital inputs can be used to save, lock and set the counter value. High-precision EtherCAT distributed clocks (DC) facilitate synchronous reading of the position value. In addition, a wide range of integrated functions enable the support of further applications directly in the terminal, e.g. rotary axis function, workpiece measurement and standstill monitoring.
