Bosch Rexroth AG R911170755-GA1 Terminal Module

The Bosch Rexroth R911170755-GA1 Terminal Module is a four-channel digital output terminal block for the Rexroth Inline I/O system, identified as R‑IB IL 24 DO 4‑PAC. It delivers four 24 V DC outputs, each capable of switching up to 0.5 A at 35 °C ambient (0.375 A at 45 °C; 0.25 A at 55 °C) when 100% simultaneity is assumed. The module uses a dual-supply scheme with a 7.5 V bus‑logic supply and a 24 V supply for peripherals, and its power architecture ties the 24 V main UM and 24 V segment US to the same potential while FE (functional earth) remains a separate potential area. In terms of power dissipation, the housing consumes ≤ 0.6 W. The device is designed for inline connection via Rexroth’s inline connector, and it supports an isolation test of 500 V AC at 50 Hz for 1 minute between relevant sections. This part is cataloged as R911170755‑GA1, described as R‑IB IL 24 DO 4‑PAC (NOB).
