Macurco MRS 485
The Macurco MRS-485 output is connected via a four terminal screw type connector.
The MRS-485 is wired in the standard 2W-Modbus circuits definition with selectable built-in terminating resistors at the ends of the RS-485 bus.
The power for the MRS-485 adapter is connected via a two terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity. The MRS-485 accepts the 4-20mA output and is powered from the same connection as the detector.
The MRS-485 has the ability to interface with Building Automation Systems, Control Panels or other Control Devices that accept Modbus communications. MRS-485 operates in the RTU Modbus Transmission Mode.
The Macurco 6-series is a family of fully programmable, low voltage, dual relay gas detectors, controllers and transducers for BAS, HVAC and Fire and Security applications.
