Equipped with a double pole relay, it can efficiently switch mains and features selectable trigger and reset input polarity for added flexibility. The crystal-controlled design ensures precise timing, while the wide operating voltage range accommodates various power sources. With input and output level specifications, this timer operates reliably in temperatures ranging from -10°C to +60°C. Packaged in a sturdy cardboard carton measuring 77.9 X 47mm and weighing 80 grams, the AT-372 Ultra Timer is a dependable solution for diverse timing needs.

Specification:

• Time settings: 1 second to 64 weeks
• Operating voltage range: Wide
• Relay: Double pole
• Input polarity: Selectable trigger and reset

Time period 1 second to 64 weeks – accurate DIL switch time settings – 4 modes of operation – wide operating voltage.

• Working voltage 9.5 – 30V DC – auto selected by timer (no need to set input)
• “Pulse” activation after time out – option on two of the modes
• Selectable trigger and reset input polarity

• 1 second to 64 week time period. Selectable by DIL switch – crystal controlled for accurate time
• Double pole relay will switch mains – contacts rated at 8 Amps
• Four modes of operation

Setting time period – seconds, minutes, hours, days and weeks – could not be simpler – just look up the time required in the “time table” and set the DIL switch accordingly
Operating Mode A – trigger applied – times out and activates the relay – if auto link is fitted relay drops out after 20 seconds and is then “waiting for next trigger”
Operating Mode B – trigger applied – relay activates for time period then drops out. It is then ready for the next trigger.
Operating Mode C – once applied the trigger must remain for the duration of the time setting to activate the relay. An example of this would be monitoring a fire door. If the door is opened the timer starts (say it has been set for 3 minutes) if the door closes before the three minutes nothing happens, however if the door is open after the 3 minutes the relay will activate – if auto link is fitted relay drops out after 20 seconds and is then “waiting for next trigger”

Activation – trigger and reset input polarity is set by jumper links.
