4-channel SSR relay module 240V/2A triggered by high state

Module with SSR relay with a load of up to 3 A. It communicates via the USB interface and does not require additional power supply. Numato Lab SSRP20001-DC

Module with a 12 V relay and a timer. It allows you to turn the device on and off cyclically at a specified time using potentiometers. It can also operate in single trigger mode, which allows the device to be turned on after a signal has been applied for a specified period of time. The operating time can be adjusted from 1 s to 100 s or from 1 s to 15 min

Module with 2 SSR relays with a load of up to 3 A. The board communicates via the USB interface. Numato Lab SSR20001-DC

Module with a relay and WiFi communication. Compatible with ESP-01 or ESP-01S
