1492-IFM40D24 | Terminal block

LED Indicating Standard with 24V AC/DC LEDs1. Compatibility — To ensure proper operation with the I/O module, do not exceed the voltage and current ratings of the IFM. When this IFM is used with a hard contact (relay) output circuit that switches an inductive load, surge suppression must be used (e.g., a 1N4004 diode reverse-wired across a DC load).2. Wiring — The LEDs are powered off the two-position terminal block. Make only one connection to the power source for normal operation. Refer to the Label Section on page 181. For Field-Side Wiring Diagrams3. Isolation — The LEDs are connected to one common. All of the I/O devices used must reference the same power source.
