Veris H704-42 Modbus Solid-Core Branch Circuit Monitor, 42 circuits (3/4")
CAD (change) 
The H704 uses banks of solid-core mini-CTs to monitor the individual circuits in a panelboard. Accumulated information can be transmitted across an RS-485 network to a Modbus host and/or viewed on an optional local display (H8936). Data updates occur about once per second to provide timely maintenance information. As a circuit approaches capacity, warning and alarm levels trigger to warn of the need for intervention to prevent unexpected breaker trips and costly downtime.
APPLICATIONS
- Load based cost allocation
- Overload protection
- Load management
- Load balancing
- Lighting circuits
The Bad:
The Bottom Line:
Full Review
- Up to 63 H704s can be networked on one Modbus RS-485 drop… simplifi ed wiring
- A H704-42 reports current consumed on each circuit in the panel board...one product covers multiple points
- 3/4 or 1 inch on center current sensors accomodate standard breakers...easy installation
- Provides Modbus registers for current limit warnings and alarms...prevents breaker trips
- Integrates with available network display for local indication
