Sintrones SBOX-2625-SF-2S Intel Twin Lake N150 Compact Embedded Computer with Digital I/O and Dual 2.5GbE

Small automation jobs often come down to a handful of signals: a door switch, a stack light, a relay that starts a conveyor. The Sintrones SBOX-2625-SF-2S puts four digital inputs and four digital outputs on a compact embedded computer, next to two RS-232/422/485 ports, so those signals and the serial devices around them can share one box. It is the DIO build of the SBOX-2625-SF series, in a steel case of 182 x 106 x 40 mm.

An Intel Processor N150 handles the computing, with four Twin Lake cores up to 3.6 GHz and Intel Graphics. There is one DDR5-4800 SO-DIMM socket for up to 16 GB, a TPM 2.0 and a watchdog that resets an unresponsive system. Two HDMI 2.0b ports run at up to 3840 x 2160 and 60 Hz for an HMI screen or a line display. The operating systems Sintrones lists are Windows 11 IoT Enterprise LTSC and Ubuntu 24.04 LTS.

The digital inputs accept 5 to 36 V DC and the outputs switch 5 V at 100 mA. Networking is two Intel I226-LM 2.5GbE ports, and the SBOX-2625-SF-2S keeps two USB 3.2 Gen 1 and two USB 2.0 ports, plus line-out and mic-in. An M.2 Key B combo socket with SIM support takes an optional 5G or LTE module or an M.2 2242 SATA SSD, an M.2 2230 Key E socket takes optional Wi-Fi, and a 2.5″ SATA SSD holds the system. We supply it configured and tested, with memory, the SSD, the OS image and any wireless module fitted.

Power is 9 to 36 V DC on a two-pin terminal block with over-current, over-voltage, surge and reverse polarity protection, which suits 12 V and 24 V cabinet supplies. The computer is rated from -30 °C to 60 °C with 0.6 m/s airflow, tested on a heat spreader to simulate cabinet mounting, and lists CE, FCC Class A, UKCA and IEC/EN 62368-1. It wall-mounts and weighs 720.5 g. The SBOX-2625-SF swaps the DIO for two more USB 2.0 ports, and the SBOX-2625-SF-3S adds a third serial port.
