I/O configuration — 16 inputs, 16 transistor outputs
The FX2NC-32MT carries 16 sink/source inputs rated at 24V DC, 7mA typical / 5mA per point — the lower 5mA figure is the nominal draw for the input circuit, meaning the PLC can read standard 3-wire sensors and dry contacts without loading the signal source. The 16 outputs are transistor type, rated 0.1A per point with a total of 1.6A per common — this suits high-speed switching of solenoid valves, indicator lamps, or small contactor coils in a cold-storage panel where relay chatter at low temperature is a concern. Total I/O count is 32 points, typical for a compact machine controller handling discrete signals without an expansion rack.
Power supply tolerance for cold-chain environments
The unit accepts 24V DC with a wide tolerance of +20% / -15% and ripple up to 5% — this range covers the voltage sag common when a large compressor or evaporator fan motor starts on the same DC bus, so the PLC stays running through the transient.
