MR310, 320 Low-Voltage, Low-Current TTL+ Relays		All Engineering Data Pages
MR 300 Series Relays provide virtually endless options for low-voltage application interconnectability. This robust relay is available in SPDT or DPDT configurations. Available in enclosure, snap-track, or spacer mounted versions and single or multi-unit assemblies. Enclosure configurations available with red or gray covers and provide ‘energized on’ LED viewing port(s). No special tools are required for installation. Industrial/commercial sized PCB. Code required approvals in place.
A sampling of mounting, enclosures, and configurations shown above. User-Selectable Operation Modes: • Super-low current dedicated 24VDC trip mode allows for a variety of fire alarm driver type applications. • TTL level trip is "real world" useable for building control/ relay/annunciator driver board applications. • Trip / host "bridged" mode provides a 12-27.3VDC standard package for security and general purpose solutions. Options/Configurations: • Available in SPDT or DPDT configurations • Available in enclosure, snap-track, or spacer mounted versions • Available in single or multi-unit assemblies • Track mount version allows for either adhesive, DIN rail or single/dual screw mounting • Spacer configuration provides for screw or optional DIN/"A" rail mounting • Enclosure configurations available with red or gray covers
The MR3 utilizes all pre-qualified, reliable hi-grade U.L. recognized components. Trip circuitry is 100% opto-isolated for complete non-interference and protection. Easy reversible selectability for trip/host voltages, low and ultra-low current trip operation which allows proper matching of trip to type of load switched (no tools necessary). Both trip and host inputs are diode protected against accidental reversed polarity DC hook-up. These relays are polarized so that either or both may be supervised and/or utilize input voltage logic for complex multi-criteria operations. Both trip and host are universal for use with standard TTL, fire, security and building control voltages. All field wiring terminations are done with positive clamping-action captive screw commercial/industrial terminals (#12 to #22 AWG).The design provides for positive or negative trigger inputs, and an integral energized (on) red LED indicator.There is also zener diode protection across relay coil. Environmental temperature ratings are between 32°F to 120°F @ 93% RH non-condensing / freezing.The unit provides for use of two differently referenced power sources on trip and host inputs.The MR3 will not false trip on less than four volts and allows regulated and un-regulated power sources.
