Product Description:
The IP5109-B310-0000 is a single-channel incremental encoder interface produced by Beckhoff in the IP Compact Box Units series. Intended for field-mounted EtherCAT stations, it receives differential A/B/Z signals from rotary or linear encoders and forwards precise position or speed information to the PLC. By combining counting, gating, and latching inside a compact enclosure, the unit streamlines feedback handling on conveyors, pick-and-place axes, and other distributed motion tasks in industrial automation.
It evaluates incoming pulses with a 16-bit binary counter dedicated to one channel, allowing precise tallying while conserving memory in the process image. The channel count is 1, so the module directs all resources to a single encoder path, improving determinism. Pulse edges are accepted up to 1 MHz, and the internal time-stamp resolution of 200 ns supports accurate velocity measurement at high shaft speeds. A gate line with the action High = stop can freeze the counter asynchronously; additional features include a rising-edge latch, a 16-bit zero-pulse register, and a 2 × 16-bit plus 1 × 8-bit control/status image for index referencing and diagnostics. Sensor power is derived from the control voltage rail and presented as 5 V logic for standard TTL encoders.
Field wiring is handled by industrial connectors: the encoder leads attach through an M23 screw-in 12-pin plug, while a dedicated gate or latch conductor is available on a rugged M12. Downstream EtherCAT continuation is provided via a single M8 socket with four pins, and module power is looped through another 4-pin M8 feeder. The board supplies 5 VDC to the sensor port and can deliver up to 0.5 A in total, removing the need for an external encoder supply. All power is sourced from the upstream control voltage, keeping logic isolated from motor circuits and maintaining stable levels during machine start-ups.
