Module with 8 relays with a voltage of 12 V and a load of up to 7 A. The board communicates via the Bluetooth wireless interface. Numato Lab BTRL001

Module with 8 relays and 8 IO pins and 8 analog inputs. It communicates via the RS485 or USB interface and supports the Modbus RTU protocol. Numato Lab NLRE1001-A

This SPST solid-state relay module allows for safe switching of DC circuits up to 60 V and 7 A, offering galvanic isolation and low conduction resistance (approx. 30 mΩ) thanks to the use of back-to-back MOSFET transistors. It features fast switching time (up to 1 ms), low control current consumption (approx. 10 mA), and the ability to control a signal from 2.7 to 40 V. Its compact design, lack of mechanical components, and the ability to mount on 2.54 mm connectors or screw terminals make the module a durable and quiet solution for systems requiring reliable isolation and long service life.
