R-IB Interface Modules

R-IB Interface Modules are Bosch Rexroth Inline terminal modules used to distribute station power, collect digital input signals, and measure analog process values in Rexroth Inline automation systems. The series includes a 24 V power terminal that supplies the main circuit and can also feed the segment circuit, with external fuse protection required and an 8 A limit across the combined potential jumpers. Digital input versions provide 16 channels for 24 VDC sensor signals, support 2-wire and 3-wire wiring methods, communicate over the 500 kbit/s Inline local bus, and process input data through a 16-bit channel. Analog input versions add two separately configurable single-ended measurement channels for voltage or current signals, including 0–10 V, ±10 V, 0–20 mA, ±20 mA, and 4–20 mA ranges, with both channels updating in less than 1.5 ms. Built for IP20 cabinet installation, the modules use Inline spring-cage terminals, local diagnostic indicators, defined isolation between logic and I/O supply areas, and industrial operating capability from -25 °C to +55 °C.
