4. V to 24 V A24 DC supply is needed to power the relays When driving the relays with high voltage drivers an SE1100 can be located up to 15 m 50 feet from the controller The opto isolation between the controller and the relays provides an extra level of assurance to guard against noise from high voltage transients The LEDs on the relay board indicate the status of the relays When an LED is on the relay associated with that LED is energized When an LED 18 off the relay is in a default state The default state is for the common terminal to be connected to the normally closed terminal The onboard linear regulator provides the regulated 5 V to all the logic elements The relays and the LEDs are driven with the unregulated DC input voltage Altogether the SE1100 draws approximately 80 mA from the DC power supply input when all the relays are turned on 6 Overview SE1100 Hi m o Q m
