Key ratings and what they mean for your panel
The NX-TC3406 has 4 analog inputs for RTD/thermocouple and 4 voltage outputs for external SSR control. No power supply voltage is specified in the module datasheet. Mounts on standard DIN rail and uses spring terminals – no screwdriver needed for the wiring, just press and insert. The operating range is 0°C to 55°C, so keep it inside a ventilated enclosure if ambient temps climb. Approvals cover CSA, cUL, cULus, KC, NK, and UL – that covers most North American and Korean marine specs. No RoHS or REACH listed in the records, but the module is electrically clean for industrial environments.
