Beuler BU509TD 12 VDC Automotive 5-Pin SPST Time Delay Relay with adjustable timing

The Beuler BU509TD is an updated version to the very cool Beuler BU508TD time delay relay. Have you ever wanted to have something stay on for some time after a momentary button is pressed? The BU509TD relay is just the relay for you. This relay is a time delay relay with adjustable timings allowing you to control any device. This relay is perfect for a variety of things such as secret compartments, safes, extended remote turn. It utilizes popular Bosch style connections and is frequently used in automotive sound and security installations. It easily switches 30 amps of current and peaks of 30 amps with minimal draw on the coil of 120 milliamps @ 12Vdc. Single Pole, Dual throw for flexible installations and multiple uses.

    Features:
  • Standard automotive style relay
  • No mounting tab
  • Delay Off Version
  • Momentary pulse to trigger latching (Requires the removal of 12 volts on the trigger to initiate timer, with constant 12 volts relay is latched like an ordinary 5-pin relay, no timer)
  • Low 1volt (1k Ohm) trigger voltage
  • Adjustable time latching from 2 seconds to 3 minutes with internal potentiometer, the time delay extends or delays the termination of the relay
  • Built in diode to stop timer feedback issues
  • Internal green LED to indicate status
  • Non-removable cap
  • 20 amp / 30 amp rated contacts
  • SPDT - Single pole Dual throw
  • 12 Vdc rated coil with minimum 8 volt to trigger
  • Power consumption @ 12Vdc 120 mA
  • Idle current draw .002 mA
  • Conventional 87, 87a, 30, 86, and 85 pin locations
  • SPDT Change Over NC/NO (form C)
  • Compatible with most insulated and non insulated terminals and relay sockets
  • Dimensions 1-1/4" (W) x 1-1/4" (D) x 2" (H) with terminals
    Pin configuration:
  • Pin 30 - Must have constant or accessory 12 volts all-time, as this is what powers the circuit on the relay
  • Pin 85 - Ground
  • Pin 86 - Single pulse (+12 volts) to trigger time delay off (Constant 12 volts can be applied and once +12 volts is removed relay will stay latched for duration of timer.)
  • Pin 87a - +12 volt output (Normally closed contact - on except when time delay is active)
  • Pin 87 - +12 volt output (Normally open contact - on for duration of set time)
    Uses:
  • Low voltage trigger: input will trigger with as little as 1 volt (Constant or pulsed)
  • Momentary pulse to timed latch: use a momentary switch to trigger for a short duration (up to 3 minutes)
  • Voltage inverter: temporarily reverse the polarity to a drain (requires additional relays
    How the unit functions
  • Momentary pulse: 12 volt positive momentary pulse connected to Pin 86, once pulse goes to zero the relay will trigger for preset timing
  • Constant input: 12 volt positive constant connected to Pin 86, once constant goes goes to zero the relay will trigger for preset timing
