Remcon Solid State Low Voltage Relay Switches with Built In Transformer

Standard 3-wire relay with built-in transformer and stripped leads for the low voltage lighting systems common in homes built in the 1950s, 1960s and 1970s. Replaces the R-115.

• Replacement Unit: The R-115S replaces the old R115 electromagnetic switches. Can be used in all present applications, plus many new applications. (The R115 was only rated to 5 amps, and used 750 mA of AC control current.)

Remcon Low Voltage Devices Specifications

These relays with built-in transformers are replacements for Remcon / Amprobe relays used in low voltage electrical systems typically found in the basement or attic of mid century homes.

• Remcon Relay Switches: 6.5 Amp, 120 Volt, 100% Solid State Relay. Made in China. AC Voltage from 105 to 125 VAC. AC Current Rating: Resistive, Tungsten or Ballast Load up to 6.5A (1/4 HP max. motor load at 120V) maximum. Control Switch Closure Time: 5 milliseconds minimum. Frequency: 60 Hz. Safe control switching: 10.0 VDC max. isolated from AC line. and 10 miliamps max. Ambient operating temperature: 40 degrees Celsius max. for full rated output current.
• Operation: Switches AC power ON and OFF using low voltage control circuit. Built in transformer, with no step down transformers necessary. Momentary contact closure of control wires turns AC power ON or OFF. If there is more than one relay on a circuit, the relays must be the same type, i.e. all R115 or all R115S. They cannot be intermixed because of the difference in control currents.
• Size: 2.5" wide by 1.125" deep by 1.83" high.
• Features: Multiple relays can be controlled by a single switch. A single relay also can be controlled by multiple switches. This quality megohmmeter has a solid range of features which were designed to meet most insulation test applications.
• Installation: In metal electrical box, just insert through the knock-out opening hole. For better heat dissipation, we recommend installing with included mounting nut. Must be securely installed in metal boxes only (not in plastic electrical boxes) because solid state switches generate heat.
• Wiring Instructions: Includes wiring diagram along with hook-up directions for replacing the older R-115 (electromagnetic switch relay). A significant time and cost savings can be achieved by using light #22 cable to control relay instead of Romex or armored cable.
• Ratings: Limited lifetime warranty. UL Listed.
• Original Remcon System Features: Remcon switchplates were typically installed horizontally (sideways) with the switches rocking up and down to turn lights on/off. The curved, flared switches were pinched in and narrower at the middle and wider and taller at the top with a small dot (red for pilot lights) at the center. (Original type of Remcon mounting frames, ivory curvy rocker switches and rounded or oval wall plate covers are no longer in production.)
• New Applications for the R115S:
  • Industrial Control Applications
  • Higher current applications. (Up to 6.5 Amps, 1/4 HP)
  • Where isolated low voltage is need for safety reasons.
  • Long-distance remote operation with twisted pair wire.
  • Computer control applications.
  • Alarms.
  • Plant process controls.
  • Applications where a U.L. Listed device is required.
  • Reduce control wiring costs and electrical interference.
  • Hostile or hazardous environments.
  • Economically meet building codes in new installations.
• Hard To Find: A large number of low voltage wiring system brands were produced for midcentury houses including Sierra, GE, Remcon, Touch-Plate, Sweepe, and Bryant. These companies have mostly limited components, discontinued their product lines, or have gone out of business. Kyle Design stocks the currently manufactured lines that will still work with these older electrical systems wired for low voltage switches and relays.

Can I use low voltage Bryant, GE and Remcon switches and relays interchangeably in the same wiring system?

Bryant, GE and Remcon are all 3-wire low voltage systems, however Remcon is slightly different from the GE and Bryant systems. (GE and Bryant switches and relays may be used interchangeably.) While we are aware that some customers have tried using them together, it is not recommended. The relays have different amp and volt ratings which may cause the switches to wear our faster over time. Furthermore, the switches aren't UL listed for safety when mixed with the other system. If needing new switches for a Remcon system, we recommend replacing with Touch-Plate switches. (Note that two Touchplate button switches are required to replace each Remcon switch.)
