The Bosch Rexroth Indramat R-IB IL AO 1/SF-PAC module from the R-IB Interface Modules series is a high-precision analog output terminal for industrial control systems, featuring a 2-wire connection actuator interface and a D/A converter with 16-bit resolution. It delivers voltage (0–10 V, min. load 2 kΩ) or current (0–20 mA, max. load 500 Ω) outputs with a basic error limit of ±0.003% and transient protection. Operating at a transmission speed of 500 kbaud, it updates process data in under 1 ms. The module withstands ambient temperatures from –25 to +55 °C, draws up to 45 mA from the local bus and 95 mA at 24 V DC peripheral supply, and mounts easily on DIN rails under IP20 protection.
