MR-311/T

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. Application - Configuration is Easy, with Reversible Selectability for "LO" Range (?18.4 VDC) and "HI" Range (?18.5 VDC) Trip and Host Inputs. The Trip and Host Inputs are Opto-Isolated to Guarantee Non-Interference Between Inputs or Integrated Systems. 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.
