  • Relays may be energized from a voltage source of 18 to 35VDC or VAC, 120VAC or 230VAC
  • Each relay position contains a red LED, which illuminates when the coil is energized
  • Single, dual or triple relay modules may be "snapped apart" from standard 4-position master
  • DC input is polarized
  • Continuous Duty Use
  • UL recognized relays rated at 10,000,000 mechanical operations
  • UL Listed as a Control Unit Accessory
  • UUKL Listed


The MR 100 Series Multi-Voltage Control Relays offer SPDT resistive contacts which may be operated by one of four input control voltages. A single relay may be energized from a voltage source of 24VDC, 24VAC, 120VAC or 230VAC by wiring to appropriate input terminals.

Each relay position contains a red LED which indicates the relay coil is energized. Relays may be "snapped apart" from a standard 4 module assembly and used independently. These devices are ideal for applications where local contacts are required for system status, remote contacts for control of electrical loads and general purpose switching. They are suitable for use with HVAC, temperature control, fire alarm, security, energy management and lighting control systems.
