MR380-1-3 Universal SM/MM E-Stop and Switch Controller

MR380-1 Fiber Optic E-Stop DIN Rail Mount Controller
MR380-1 Fiber Optic Emergency Stop Controller


MR38X Series Universal DIN Rail Mount Controller

MR380 Fiber Optic Signaling Sensors are used anywhere where conventional electromechanical controls cannot be used – both harsh and hazardous environments. The MR380-1-3 Universal Controller Module is the active optical and electrical interface for all MR380 series ZapFREE® Emergency Stop, Microswitch, and other Signaling Sensor products. This controller is compatible with both multimode (50/125 and 62.5/125) and single mode (9/125) based sensors in the MR380 series.


  • DIN rail mountable module
  • Ex rated Inherently Safe Optical Radiation
  • Controller is installed outside the hazardous area
  • Interference-free transmission up to 10km (6 miles) with single mode fiber
  • Universal controller supports both multimode (50/125 and 62.5/125) and single mode (9/125) fiber links
  • Depending on sensor type, multiple sensors can be optically wired in series


  • DPDT relay contacts
  • Digital status outputs, 5V and 24V
  • Depending on sensor type, digital outputs and relay implement know default failure state
