18 digital inputs, power relays and 0–10 V analog I/O — the most versatile PEAK variant.
NEXTuino PEAK PLUS FLEX combines extended digital inputs, high-current power relay outputs and 0–10 V analog channels in a single DIN-rail module. Designed for 24 V automation systems that need to control heavy loads while reading analogue sensors and commanding variable-output actuators.

18 digital inputs detect dense sensor networks while 16 A relays switch motor contactors.
0–10 V outputs command proportional hydraulic or pneumatic valves with precision.
Power relays handle heating element loads; analog inputs read thermocouple transmitters.
Ethernet connects to SCADA HMI and remote monitoring systems over TCP/IP.
Dense digital I/O handles sensor-rich packaging machinery with analogue fill control.
Mixed I/O for damper control, VSD commands and temperature sensor reading.
No. Like the FLEX variant, the PLUS FLEX does not include an on-board RS-485 transceiver. Choose the standard PEAK or PLUS if RS-485 Modbus RTU is required without an external module.
Yes. The 5 power relay outputs are rated to 16 A / 240 V AC — suitable for motor starters, heating elements, large solenoid valves and similar industrial loads.
The PLUS FLEX replaces the FLEX's 10 standard relay outputs with 5 high-current power relays. The analog I/O and digital I/O counts remain the same.
