The four way relay card provides four single pole double throw relays with connection terminals to the common (C), normally open (NO), and normally closed (NC) contacts.
The relay contacts are rated at 1 A @ 0 to 30 VDC; reducing to 300 mA @ 48 VDC. If fitted to a DGP, two relay modules can be connected together in daisy-chain fashion to provide up to eight relays on ATS120xE series. When fitted to the control panel or four to eight door/ lift expander, only one relay module is allowed.
An LED is provided for every relay to indicate activation.
