Macurco releases the MRS-485 adapter, an accessory used to convert the 4-20mA analog signal from the firm’s 6-Series detectors to a digital signal for use with multipoint addressable systems, according to the manufacturer.
The device 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 adapter is connected via a two-terminal screw type connector, 12 to 24 VAC or 12 to 24 VDC and no polarity.
Powered from the same connection as the detector, the device accepts the 4-20mA output and has the ability to interface with building automation systems, control panels or other control devices that accept Modbus communications.
