Bosch Rexroth R911170900 Product Description
The R911170900 is a Rexroth Indramat I/O module, also labeled as RMK12.2-IBS, used for INTERBUS fieldbus remote digital I/O expansion. It is a compact rack-mount slave module for Indramat legacy automation systems, handling digital input and output signals between field sensors/actuators and the main controller via INTERBUS. It is widely used as spare part for older production lines equipped with Indramat DIAX, EcoDrive and PPC motion controllers. This product is end-of-life, no longer in original production, only available as surplus or refurbished spare inventory.
Product Features

Frequently Asked Questions
A1: R911170900 is the Rexroth material number, the module type designation is RMK12.2-IBS, INTERBUS remote I/O module.
A2: Only compatible with same RMK12.2-IBS variant. Different RMK models have different channel count or bus interfaces, cannot be swapped without checking I/O definition and bus protocol.
A3: Check bus cable continuity, bus termination resistor, 24VDC module power supply, bus wiring sequence, and master side INTERBUS configuration.
A4: Hot swap is not recommended. Disconnect 24VDC power before removing module; otherwise it may trigger bus interruption and machine emergency stop.
A5: Use anti-static wrist strap during handling. Avoid overvoltage on I/O terminals. Store in dry environment, keep original packaging for spare stock.
