Connection diagram
A connection diagram illustrates the wiring for the EMM 3-24DC/500AC-IFS module. It shows connections for power supply, digital inputs (IN1-IN4), digital outputs (O1-O4), thermistor input (Th1, Th2), and current measurement inputs (I/L1, I/L2, I/L3 and T1/L1, T2/L2, T3/L3). It also indicates connections for external switching modules and a motor (M).
