The eight way clocked relay card ATS1811 provides eight 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 or 300 mA @ 48 VDC. Relay cards can be connected together to provide up to sixteen relays when connected to an expander and up to sixty-four relays in a four to eight door/lift expander.
An LED is provided for every relay to indicate activation.
