Schneider Electric 8030-RIM-731 Rack Interface Module

Schneider Electric’s Square D 8030-RIM731 Rack Interface Module is a 64-point digital input module designed for SY/MAX Class 8030 racks, handling 64 discrete field signals from 22–33 VAC RMS or DC sources. Each input channel uses optical isolation from the backplane (up to 1,400 VDC) and includes a dedicated status indicator, giving clear, real‑time visibility of every input’s state. The module draws about 1.7 mA at 22 V and 2.5 mA at 32 V per channel, with a total load up to 600 mA from the SY/MAX power supply at 100% duty cycle, and exhibits a nominal ON/OFF switching time of 8.3 ms. Turn-on thresholds are around 21.5 VDC or 20 VAC RMS, while turn-off thresholds are about 10 VDC or 11 VAC RMS, with corresponding currents of 1.5 mA DC/0.5 mA AC (turn-on) and 0.5 mA DC/0.5 mA AC (turn-off). The per-channel input impedance is 12.4 kΩ, and the module is intended to plug into a Class 8030 I/O rack to relay input status to the SY/MAX controller. With 64 indicators, the RIM731 provides a compact, isolated interface for monitoring a large bank of sensors or switches in industrial automation environments, making it a suitable choice for legacy SY/MAX installations that require reliable digital input consolidation in a single rack module.
