Symax 8030-RIM-123 Input Module

The 8030-RIM-123 is a SY/MAX Class 8030 high-speed input module for eight input channels in a SY/MAX rack, designed to feed rapid voltage or current signals into the controller for real-time logic and control tasks. It draws about 875 mA from the rack’s 5 V DC power supply and requires a 5 VDC supply; its power draw and supply requirements are specified for reliable operation within SY/MAX installations. The module’s input circuitry presents 250 ohms of impedance on current inputs, with exceptionally high differential and common‑mode impedance (on the order of 10^13 ohms), and it offers a CMRR of 84 dB from DC to 60 Hz at 1 kΩ source imbalance, supporting precise signal discrimination in noisy environments. Input ranges are selected via five DIP switches and include plus/minus 10 V, plus/minus 5 V, 0–10 V, 0–5 V, 1–5 V, and a 4–20 mA mode, enabling both voltage and current signals to be read depending on the field device and wiring. A running-light indicator on the module confirms the logic circuitry is active, and the unit is rated for ambient temperatures from 0 to 60 C. Note that contemporary catalogs and secondary sources indicate the 8030-RIM-123 is no longer produced new by Schneider Electric, with older references cataloging it as a legacy module; refurbished or used units remain available from third-party suppliers.
