Product Description:

The RZP01.1-G2 is an option module in the RZP Option Modules series manufactured by Bosch Rexroth Indramat. It installs on compatible drive controllers to condition incremental encoder and sensor signals for closed-loop motion tasks in industrial automation. By combining differential receivers, local supplies, and a dedicated data interface on a single card, the module streamlines feedback wiring between the motor, the drive, and higher-level control hardware, which helps preserve signal quality across the feedback path.

The A/B input stage presents an impedance of 120 Ω, letting long shielded encoder cables terminate correctly and helping avoid reflections. It withstands differential swings up to ±20 V, so transient overvoltage will not damage the circuitry. A separate auxiliary rail of +15 V powers internal comparators, while the data pair leaves the board through an RS-485 transceiver that mates with the X48 Sub-D 15-pin connector. The encoder output can supply up to 300 mA, which allows incremental sensors or line-driver encoders to operate without an external supply. Incoming position pulses are handled at high frequency to match the timing requirements of fast rotary axes.

The logic domain and the encoder reference rail share an operating level of +5 V, and an additional jumpered sensor output delivers +10 V when single-ended sensors must be energized. Both the input and the dedicated output driver comply with a ceiling of 300 kHz, and the outgoing differential lines are translated by an RS-422 driver connected to the X49 Sub-D 9-pin port. The board occupies only 100 x 89 mm inside the drive rack, so it fits beside other option cards even in compact enclosures. Its 3K3 classification indicates operation in control cabinets with controlled humidity and possible non-condensing dust.
