8 CH 20A Relay Switch Module

Model No:RL.08.20A

The 8 CH 20A Relay Switch Module serves as a system switch execution unit, typically installed ina distribution box, rail-mounted, occupying 8P module units. It provides 8 channels of 20A relay switching, using magnetic latching relays. The module features a built-in mechanical forced cut-off switch, enabling relay operation even during system crashes or power outages.Each circuit can independently control the switching of 4400W lighting fixtures.Controls lighting on/off, DC/AC equipment power switching, dry contact opening/closing, and high/low-voltage curtain operation.Supports YC-BUS /RS485 control.
