The MR-311/T (SPDT) Series Relays provide for the use of two differently referenced power supplies on the trip and host inputs. Both inputs are polarity sensitive and diode protected. Both the trip and host inputs are jumper selectable for dual ranges to optimize power consumption. Single module come complete with track mounting hardware which facilitates installation in standard cabinets.
Brand Information
The MR-310 Low-Voltage, Low-Current, Opto-Isolated Relays protect sensitive devices. Provides virtually endless options for low-voltage Application interconnectability.
Brand Features
SPDT
Each relay position contains a red LED, which indicates when the relay coil is energized.
Multi-position relays may be “snapped apart” and used independently.
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.
Both inputs are polarity sensitive and diode protected.
Both the trip and host inputs are jumper selectable for dual ranges to optimize power consumption.
Application configuration is easy, with reversible selectability for “LO” range (≤18.4VDC) and “HI” range (≥18.5VDC) trip and host inputs.
The trip and host inputs are opto-isolated to guarantee non-interference between inputs or integrated systems.
Application
Both trip and host inputs are polarized, so that either or both may be supervised, and/or utilize voltage polarity reversal logic for complex, multi-criteria operations. These relay modules are suitable for use with standard TTL, Fire, Security, and many other Building Control Systems.
