The ENFORCER SA-027HQ Annual Timer can be programmed to operate two relays 24 hours a day, over the course of an entire year. These relays can be used to control devices in many applications such as security, access control, lighting, and environmental control. The two Form C relays can each be programmed to operate in shunt or momentary mode for up to 50 unique events. Each event can be programmed on a weekly or daily schedule. Block programming allows events to be repeated on consecutive days. 10 Programmable holidays disable the timer for a single day, or for the same day every year. Two N.O. or N.C. Form C relays 10A@14VDC Each relay can be programmed for 50 events, for a total of 100 individual programmable events The 100 programmable events can be set weekly, daily, or hourly, over the course of an entire year Password protection can be turned ON or OFF One egress input per relay (2 total) Block programming allows events to be repeated on consecutive days First-person-in function interrupts the normal operation of the annual timer Event outputs can be programmed disable, ON, OFF, shunt, or momentary (1~99 seconds) 10 Programmable holidays Can be programmed for password protection Tandem mode allows both relays to operate simultaneously EEPROM Memory for safe data protection in case of power failure Built-in clock backup battery Built-in backup battery charger for external backup battery use Compensates for leap years Can be set for Standard or Daylight Saving Time Alphanumeric backlit LCD display for easy programming Specifications Operating Voltage 12~24 VDC/VAC Number of Relays 2 Relay Rating 10A@14VDC Current Draw 100mA@12VDC Number of Programmable Events 50 for each relay, 100 total Blue LED On- Power is ON, OFF- Power is OFF Number of Programmable Holidays 10 Battery Charging Current 90mA Security Code 4-digits, numeric, ON/OFF Dimensions 4-3/16″ x 3-1/16″ x 1-1/4″ (107 x 78 x 31 mm) Weight 5.8-oz (164g)
