AC or DC DPDT Power Relay

with Screw Terminals and Indicator Light

Auxiliary power relay with DPDT double-pole, double-throw (2 form C) contacts, screw terminals, diode protection and an LED indicator light.

May be used with an IR train detector to control high current accessories or to switch track power to automatically stop and start trains. A safety feature for crossings and hidden storage tracks, or to automate staging yards. See the how to automatically stop or start trains page.

Application notes:

3 rail track block
3-rail block detector circuit
Can be used to replace a Lionel 153C pressure switch.
  • On-board LED indicator light simplifies set-up and troubleshooting.
  • Flyback suppression diodes for circuit protection.
  • Easy to use screw terminals, no soldering.
  • Size: 1.3 x 1.5 x 1.0 in. (3.3 x 3.8 x 2.5 cm) W x L x H
Choose the relay with a coil voltage that best matches your power supply voltage.
A higher coil resistance will draw less current from your power supply.
MRAPR-9v  $9.50
• 8-14 volts AC or DC coil voltage
• Coil resistance 200 ohms
• DPDT contacts, 8 amps, 30 volts
This relay replaces part no. MRAPR-5.
MRAPR-12v  $9.50
• 10-17 volts AC or DC coil voltage
• Coil resistance 360 ohms
• DPDT contacts, 8 amps, 30 volts
This relay is the same as old part no. MRAPR-8.
