Ttl Relay Module

Its flexible inputs will accept a wide variety of control signals.

Ttl relay module.

Selectable input allows activation of output relays on a direct acting or reverseacting signal. Ttl 5 v dc output. The module utilises a high quality 3v relay that can handle up to 10a c. Each one needs 15ma 20ma driver current and equipped with high current relay.

Then upload the code. With this relay board any logic level signal 5v or higher voltage signal up to 30v can be used to control a relay. 1 pcs serial ttl 4 channel relay control board for asr m08 a voice recognition module product information package dimensions 3 39 x 1 34 x 0 47 inches item weight 1 6 ounces manufacturer senmod asin b01fdd510c best sellers rank 697 299 in electronics see top 100 in electronics. The versatile relay urm series relay module can switch up to eight 15 a loads using low level input signals from plcs process controllers and indicators.

Connect the vcc and gnd pins of the relay module to the arduino s 5 volt pin and gnd pin. And check the relay is turning on and off in a 1 second intervals also the led of relay module will turn on and off. Short circuit proof 24 v dc max. The versatile relay urm series relay module can switch up to eight 15 a loads using low level input signals from plcs process controllers and indicators.

Its flexible inputs will accept a wide variety of control signals. Solid state relay module emg 17 ov ttl 24dc 2 2943259 power solid state relay with led and protective circuit in input and output circuits input. Selectable input allows activation of output relays on a direct acting or. Then connect the relays input pin the pin comes from the transistor s base pin to the arduino s digital pin 13.

A wide range of microcontrollers such as arduino avr pic arm and so on can control it. This is a 5v 4 channel relay interface board be able to control various appliances and other equipments with large current. Specially designed for low voltage devices the digital relay module is not only compatible with 5v arduino boards but with 3 3v devices such as the raspberry pi and beagleboard black. The relay contacts are electrically isolated from the rest of the board which allows the board to be used in a wide variety of applications including both ac and dc loads.

It can be controlled directly by microcontroller arduino 8051 avr pic dsp arm arm msp430 ttl logic.
