Numato Lab - 4-channel relay module 12V 7A/250VAC + 6GPIO - USB

The module is equipped with four relays JQC-3FC with a coil supplied with voltage of 12 V. The system is controlled directly from the USB connector. In addition, the module has 6 GPIO pins, 5 of them working as analog inputs. Works with voltage of 5 V.

All pins can be individually programmed as inputs or outputs. The module can be controlled from any application with a serial console, for example, RealTerm. The device supports user-friendly commands, e.g. "relay 1" turns on relay 1. The full list is given in the user guide. The manufacturer also provides source codes of programs in different programming languages.
