2 Channel Programmable Relay Module - programmable module with 2 relays

Module with 4 digital inputs, 4 outputs and 6 analog (current) inputs. It communicates via the RS485 interface and supports the Modbus RTU protocol. The board is enclosed in an industrial housing. Wellpro WP9038ADAM

The remotely controlled modulation module MOD-34 / AZ allows wireless load control with up to 10 A current consumption via a relay. It does not contain nRF24l01.

Iduino relay module with 2 channels and optoisolation, enabling control of loads up to 10 A at 250 V AC or 110 V DC. Powered by 5 V, it is ideally compatible with microcontrollers and development kits, providing safe and convenient circuit switching.

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.
