MT52 remote meter for RS485 controllers Overview The MT52 remote meter connects to controllers with RS485 communication to provide realtime monitoring, local parameter programming, and onsite alarm reporting. It installs easily, draws power from the controller, and gives clear visual and audible feedback on controller status and system performance. Key benefits Simplifies monitoring and setup by identifying the connected controller automatically and displaying type, model, and relevant parameter data. Reduces downtime with realtime fault display and acoustic alarms that alert operators immediately to failures. Eliminates the need for a separate power supply because power and data share the same connection to the controller. Improves operational visibility through a large multifunction LCD that shows digital, graphical, and text information at a glance. Extends reach and reliability over longer distances using RS485 communication and an RJ45 port. Main features Model: MT52 Automatic controller detection and display of controller type, model, and parameter values Largescreen multifunction LCD presenting operational data and system status in digital, graphic, and text formats Six navigation keys for direct, convenient, and fast operation Realtime energy statistics recording for ongoing performance tracking Power and data share the same lead, so no external power supply is required Realtime monitoring and acoustic alarm for controller fault information RS485based communication with longer transmission distance and RJ45 communication port Standard communication cable length: 2 m; maximum cable length: 50 m Technical specifications Selfconsumption: Backlight ON < 23 mA; Backlight OFF < 15 mA Faceplate dimension: 98 mm x 98 mm Frame dimension: 114 mm x 114 mm Communication port: RJ45 Communication cable: standard 2 m, maximum 50 m Net weight: simple package 0.23 kg; standard package 0.32 kg Operating temperature range: 20 C to +70 C Compatible with controllers featuring RS485 communication Powered directly by the controller to improve conversion rates Typical applications Building automation and HVAC: Local monitoring of controllers for pumps, fans, and building energy systems to view parameters and receive immediate fault alerts. Industrial control panels: Onsite display and navigation for controllers in production lines, enabling quick parameter checks and troubleshooting. Energy systems and generation: Monitoring inverters, charge controllers, or generator control systems where RS485 communication is used and remote display is needed. Why choose the MT52 The MT52 provides a practical, durable, and easytooperate interface for RS485 controllers. Its direct power arrangement, clear display, audible alarms, and extended communication capability help operators monitor systems more efficiently and respond faster to faults without adding separate power wiring or complex setup.
