M2 Wireless Monitoring System

murphy.M2wirelessThe M2 Wireless Monitoring System is a simple and unique system. The M2 Wireless system is well suited for many control applications. Configured via Modbus RS485 network, users can utilize Murphy’s MConfig software, 3rd party Modbus software, and/or configured using programmable logic controllers. When used in a control system designed by Murphy, the Gateway, remotes and controller are defined and functioning to meet exact specifications for a variety of applications.

The Gateway (HUB) of the system continuously monitors input signals from remotes via an RF network. Digital Remotes are monitored via a switch to determine fault. Set points for Thermocouple Remotes are monitored in the remote. When an out-of-limits event occurs, the remotes will provide signals back to the Gateway. The system controller will read this data from the Gateway, the controller will then stop, shutdown or control equipment to change conditions.

The M2 Wireless system provides NEAR real-time data via a communication port to a connected control system. This advanced system offers multiple options for remote placement of en-devices deemed too costly to run conduit or prohibited by laws. (Example: crossing under a roadway with conduit).

A separate power supply is provided with the model LCDT instrument. Power may be supplied by CD ignition, a 120 VAC line, or by 12 or 24 VDC battery. Intended for use with all Swichgage® instruments without “OS” option.

LCDT System
The basic LCDT system consists of (1) the LCDT module, (2) the terminal strip and cable assembly, and (3) the power supply.

Terminal Strip and Cable Assembly
The plug-in type Terminal Strip has 50 screw-type connections for normally open sensors and 100 connections for normally closed sensors. The terminal strip can be connected to the LCDT module with the 36 in. (914 mm) long flat ribbon cable.

Power Supply
You have a choice of input power supplies: LCDT-PS-CD (R)-P and LCDT-PS-CD-N for CD ignition or LCDT-PS-120/24/12 for 120 VAC or 12 or 24 VDC.
