Description
This four channels Relay Module can be used to control the lighting, electrical and other equipments through the digital IO port. The digital input circuit is optically isolated from the relay, so your controller is protected from voltage spikes and surges. The module is controlled with 5V signal and they are pre-soldered. A logic “LOW” to the control pin will turn the relay ON. Specification – 4 independently controlled relays – 5V TTL Digital interface – On-board back EMF protection – Opto-isolated inputs – LED indicator for each channel – Contact Rating (Resistive Load):10A 250VAC Documents: – Schematic Dimensions: 75.2(L) x 55.0(W) x 20.0(H)mm Weight: 60gx
