DOUGLAS LIGHTING CONTROLS WR-8824 24-Output Douglas Lighting Controls Scanner

Relay scanners have wide application in low voltage lighting controls. Relay scanners permit a large group of relays to be switched together. Relay scanners also permit each relay in the group to be individually controlled. WR-8824 relay scanners have 24 outputs that switch Douglas relays. Standard Douglas relay switches can be used to actuate relay scanners. Automatic devices such as time clocks are also easily connected to relay scanners. Several scanners can be controlled by one switch or timer contact. Simply wire the inputs of the scanner's in parallel and connect to same switch and/or timer.
