Product description: Numato Lab - 4-channel 2 A + 4 GPIO - USB relays
The Numato Lab module is equipped with four relays DPDT HFD27 / 005-S with a coil powered with a voltage of 5 V. The board can be controlled from a computer using a USB port or via a 5-pin GPIO connector, operating as analog inputs or digital inputs / outputs. Relay contacts can switch loads up to 2 A with voltage up to 60 V DC / 240 V AC . The module is controlled by simple commands using a serial terminal or programmed in VC ++ / VB / VBA / Perl, Python, etc. The module with relays is powered by 5V from the miniUSB port.
Module support
The outputs of the module can be individually programmed as inputs or outputs. GPIO pins and relays can be controlled by any serial console application, eg RealTerm . The device supports user-friendly commands, eg " relay on 1 " activates relay 1. For a complete list, please refer to the user manual . The manufacturer also provides source codes for programs in various programming languages.
