The NX-TC2406 is an active-production temperature control module in Omron's NX series, offering two analog inputs for temperature sensor signals and two voltage outputs rated for driving external SSRs.
How the ratings decide fit
The 2 analog inputs accept standard thermocouple or RTD signals (type not specified here, but typical for NX TC modules). The 2 voltage outputs are for external SSR gate drive, so you need an SSR bank per output channel. If your panel needs four independent temperature loops, the sibling NX-TC2407 has four voltage outputs while keeping the same 2-input architecture — same mechanical and electrical footprint, so a BOM change is wiring-only, no panel rework.
