Schneider Electric NTSDDO0402K Modicon Edge I/O NTS Digital Output 4Ch 24VDC 500mA Source Remote I/O Module

The Schneider Electric NTSDDO0402K is a Modicon Edge I/O NTS discrete output module kit with 4 transistor outputs at 24 V DC, 500 mA per channel, pre-assembled on its NTSXBA0100H base. Channels wire in 1, 2 or 3 wires with read-back and over-current diagnostics, covering a -20...60 degC operating range. It mounts on a DIN rail and connects to Modicon M262 or M580 controllers.

Selection Notes

The 500 mA per-channel rating on the NTSDDO0402K fits small loads such as indicator lamps or interposing relay coils; for higher-current actuators the 2 A-per-channel NTSDDO0802K is the correct pick instead. Read-back diagnostics report the actual output state to the controller, catching a stuck or shorted output a simple command-echo would miss. For vibration- or condensation-prone panels, the hardened NTSDDO0402HK shares the same 4-channel, 500 mA rating with conformal coating and an extended -40...70 degC range.
