MRD8, Eight Channel Detector

• Senses model trains at eight places on the track.
• Solid state relay outputs for electrical isolation and maximum system compatibility.
  • Each relay can switch up to 200 milliamps (0.2 amps)
  • See the note about relay contact ratings
• Eight on-board LEDs for easy setup.
• Quick-connect terminal blocks.
• 10-pin ribbon cable connector compatible with RR-CirKits LocoNet Control Point (LNCP)™, Tower Controller (TC-64)™ and similar interface boards.
• Power required: 8 to 16 volts AC or DC, 40 milliamps.

• Standard MRD8 - each output relay stays closed as long as a train is on its sensor, and remains closed for one second after the train clears the sensor (1 second drop-out delay).
• Momentary MRD8 - each output relay closes for 1/2 second then opens, and will not close again until after the train clears the sensor and the next train arrives.
  Useful for actuating latching relays.                            

Standard MRD8 with eight pre-wired infrared sensor sets
Output relays stay closed as long as a train is on the sensor, plus one second drop-out delay.
