Senva CM02SV : Enhanced Core Module, 90-300 VAC L-N, 50/60 Hz (Combined Sensing And Power Supply Input); Supports 277V L-N / 480V 4W With Neutral Sources And 240 VAC / 415V 4W Sources; Use Alternate Models For 3W Sources That Do Not Have A Neutral
The Core Module Multi-Circuit Monitoring System is designed to measure the current, voltage, and energy consumption and other critical power parameters on up to 96 circuits. Current transformers are connected via a variety of Interface Boards optimized for different applications that connect to the Core Module via network cables. Each Interface Card monitors up to 24 circuits and the Core Module hosts up to four interface cards. The Core Module can communicate via Modbus TCP/IP, Modbus RTU as well as provides access to real time and logged data via an on board web server. Data is also transmitied wirelessly via an option cellular modem. Logged data can reside directly on the Core Module or on SD storage card with up to 32 GB capacity. The Core Module also monitors two digital inputs and provides two digital outputs.
