Install Touch-Plate's PL-RLY low voltage latching relay as a direct replacement for discontinued 1550-BPL, 2500B-PL, 3000-PL or 4000-PL relays. These 4-wire relays plug into your panel to provide latching functionality for 2-wire momentary switches.


  • for use in Touchplate's 2-wire low voltage system
  • 16A Electrical Latching Step Relay
  • PL-RLY plug-in pilot lighted relay with a 4-pin plug end (see the TPL-3000 if your relay does not have a plug end)
  • 3.5" H x 2.38" W x 0.6875" D with 10" lead length
  • Override test button allows manual advancement of the step sequence
  • Individual mechanical flags provide visual indication of contact status
  • Relay can be directly mounted to a din-rail (sold separately) with the 7" wires extending from it
  • SPST (single pole, single throw): relay only switches directly ON or OFF
  • Replaces vintage 1550-BPL, 2500B-PL, 3000-PL or 4000-PL relays that had six wires: the four low voltage wires extending from the top of the old cylinders connected to the switches and the transverter; the two wires extending from the bottom connected to the line voltage
  • NOW: the line voltage wires now connect to the two screw terminals which are not polarized so it doesn't matter which of the two terminals you feed your line voltage into
  • To Use With Pilot Lighted Switches In Older Systems From The 1980'S Onward That Used A Pilot Lighted Relay such as those in a Touch-Plate CPS system


  • Contact Current Rating: 16A
  • Max Peak Current: 30A
  • Contact Form: 3 NC - 1 NO
  • Contact Voltage: Rating 300
  • Rated Voltage/Max Switching Volt: 250VAC/400VAC
  • Function: Electromechanical Latching
  • Mounting Type: DIN Rail Mount; Panel Mount
  • Primary Type: Power Relays 
  • Coil: Pulsed at 28VDC, .05 Sec.; Power Supply: TVR-1 or TPS-0120; Class 2 Only; 60/75°C, Copper Conductors Only; Torque to Minimum 25 in./lb.
  • Wiring: Red Wire A1, Brown wire A2, Yellow Wires 1 and 2; High Voltage Wires 3 and 4
  • Made in USA
  • white plug at end of wires makes it easy to connect to the circuit board in CPS and RCP systems
  • to replace the 1550-B or 2500-BPL relays, cut off the white plug and strip down a small portion of the wires to allow for individual connections
  • designed for use with incandescent pilot lights (non-LED)
  • Made in America

Common Applications

  • Typical applications would include the control of lighting where push ON/push OFF or sequential operation is required.
