18 digital inputs, 0–10 V analog I/O and Ethernet for 24 V automation.
The NEXTuino PEAK FLEX extends the PEAK platform with 18 digital inputs and dedicated 0–10 V analog input and output channels. Purpose-built for 24 V DC automation systems that require mixed digital and analogue control — variable speed drives, proportional valves and precision sensors — all in a single DIN-rail module.

0–10 V analog outputs command variable speed drives and servo amplifiers directly.
Proportional valve control via 0–10 V outputs with position feedback on analog inputs.
18 digital inputs accommodate dense sensor networks on packaging and assembly lines.
Ethernet enables SCADA integration and remote HMI access over TCP/IP.
Analog inputs read 0–10 V temperature transmitters for PID control loops.
Mixed digital and analogue I/O suits automated test benches and data-logging rigs.
Analog inputs read voltage signals from sensors such as pressure transducers and temperature transmitters. Analog outputs drive variable speed drives, proportional valves or any actuator that accepts a 0–10 V command signal.
The FLEX does not include an on-board RS-485 transceiver. RS-485 Modbus RTU is available on the standard PEAK and PLUS variants. An external UART-to-RS485 module can be used via the FLEX's UART header if needed.
No. The FLEX is designed for 24 V DC supply. For 12 V / 24 V flexibility, choose the standard PEAK.
The FLEX CORE has the same I/O as the FLEX but omits Arduino pin headers — suited for volume OEM builds that don't need shield expansion.
