The Micronor MR387/MR388 Series Fiber Optic Emergency Stop (E-STOP) System is an innovative emergency signaling scheme that can be deployed in hazardous environments and operate over very long distances. The FO E-STOP MR380 system meets the ESTOP functional requirements per ISO 13850 and NFPA 79, and classified as a Category 2 Functional Safety device per ISO 13849-1. The optical signal levels are rated inherently safe, simple mechanical device, allowing the sensor to be safely deployed in all categories of explosive atmospheres – mines, gaseous and dust.
The FO E-Stop system can be arranged in a wide number of topologies according to the customer’s safety system requirements. Need multiple E-Stops located around the site? Check! Need multiple Controllers (Dry Contacts) dispersed around the site? Check! Need to extend long distances (up to 18km (11 miles)? Check!
Here are the MR38X series E-Stop components include:
- MR387 Duplex-LC Pigtailed E-Stop can be mounted on the user’s enclosure.
- MR387 IP-LC E-Stop can be panel or wall mounted and offers ruggedized and secure IP-LC PLUS connections with Locking Ring
- MR388 Weatherproof E-Stop that can be deployed both indoors and outdoors, even supported by same conduit used to route the optical fiber link.
- MR380-1-3 is a turn-key DIN Rail Mount Standard E-Stop Controller with built-in DPDT dry contacts, emulating the electrical connectivity of the a conventional Electro-mechanical E-Stop.
- TD5410 is a turn-key DIN Rail Mount E-Stop Loop Controller used for multi-node, dispersed and long distance E-Stop networks.
- MR380-0 is an OEM Controller for embedding in customer’s equipment.
- Above are compatible with standard telecom/datacom fiber, both single mode (OS1/IOS2) and multimode (OM1/OM2/OM3).
- For POF-based applications, the TD5412 POF E-Stop is available, and uses the customer’s POF transmitter/receciver.
- A fiber optic E-Stop link can also include the MR386 Microswitch daisy-chained with a MR387 E-Stop and TD5451 BiLoc Key Switch when secure, interlocking protocols are required.
