Description
The DIRIS MCM is a revenue grade networked Energy & Power sub-meter promoting a simplified approach to retrofit applications, while ensuring safety and code compliance.
- It has been designed using industrial best practices providing industry leading durability and ease of installation
- The DIRIS MCM supports 333mV output or Rogowski style current sensors
- It has been designed with mechanical, electrical and software features that will appeal to those seeking a simplified approach to installation and setup of energy management applications
- Advantages
- Increased Safety
- The DIRIS MCM is designed to improve installation safety and meets electrical code requirements
- Built-in optional disconnect provides path to quickly and easily service the meter independently of other circuits
- mV CT connections, can be connected and disconnected under load
- No user-direct access to dangerous high voltages, keeping instrumentation engineers safe
- Retained fasteners, ensuring screws stay securely in place and don‘t fall inside electrical panels
- Easy installation
- Wall or top cabinet mounting
- Built-in 1” conduit holes - (3) at the bottom and (3) at the top of the meter
- Push-in terminals for current sensors, no tools required!
- Clear visible numbering of CT inputs, with color coded terminals that match CT output lead wires
- Easy commissioning
- Configuration with a simple and intuitive PC application via a direct USB connection
- One IP address and Modbus slave address supports the entire meter, simplifying network integration pain points
- Patented CT configuration correction algorithm helps eliminate user wiring and setup errors while reducing owntime
- Industrial design
- Aluminum bonded enclosure
- Internal fuse protection of each hot leg
- Fuses can be replaced safely for maintenance
- Compact
- The most compact high density multi-circuit meter on the market, in an enclosed format
- Ideal for retrofitting electrical distribution centers with limited wall space
- General Characteristics
- Accepts 333 mV and Rogowski sensors
- Modbus RTU, TCP and BACnet IP communication
- Wireless 915 MHz option
- Class 0.2 accuracy per ANSI C12.1
- Need Wireless ?
- For isolated metering points where it may be impractical or costly to bring a wired communication bus, the DIRIS MCM has been designed to be plug and play compatible with the RF system for wireless communication (915 MHz) of measurements
- The RF END-Node is connected via RS485 to the power meter (DIRIS MCM) and sends measurement via wireless link to the RF HUB-Node
- No external power supply is required, as the END-Node is self-powered by the DIRIS MCM
- Each HUB-Node can communicate wirelessly with up to (8) END-Nodes
- The HUB-Node offers RS485 (Modbus RTU) and Ethernet (Modbus TCP) communication capabilities to any third-party EMS/BMS system
- WEBVIEW software
- The DATALOG H80 provides data logging of measurements and the embedded web based application WEBVIEW-L allows to visualize real time and historical measurement data
