Installation Guide

• Feed the NIM with a 24V DC SELV supply that can deliver 430 mA.
• Connect field devices to the two RJ45 ports and let auto MDIX handle cable type.
• Keep the logic bus load within 1.2 A nominal at normal cabinet temperature.
• Derate the logic bus output to 0.575 A when the ambient reaches 60–70 °C.
• Plan for 1 primary segment and up to 6 extension segments per island.
• Address no more than 32 I/O modules on a single island.
• Insert the removable memory card to store and reload the I/O configuration.
• Read the 7 LEDs (ACT, RUN, ERR, MS, NS, PWR, TEST) to confirm module status.
