Specifications

• VMS is a modular concept: VMS modules can be placed in series as long as the total DC voltage of a stack is below 500 Volt DC, 1 VMS module contains 40 analog input channels
• Common mode voltage range per VMS module +150 Volt DC
• Common mode voltage range total VMS system is 500 Volt DC
• Sample rate for all cells: 2 samples per second
• Input channel voltage range 0 to 5.0 Volt
• Cell voltage resolution: ca 0.005 Volt
• Absolute accuracy: < 0.015 Volt (measured at a common mode voltage of 40 Volt), if reference (signal ground) connected in the middle of the stack, < 0.010 Volt can be guaranteed
• Galvanic isolated CAN transceiver (>500 Volt DC)
• Galvanic isolated RS232 serial port (>500 Volt DC)
• Power supply: 24 Volt DC (isolation between input/output > 1500 Volt)
• 2 optocoupler output contacts: programmable for “warning” alarm and “fatal” alarm
• Cell voltage connector is a 44 pole high density 'D' connector
• The boards are programmable and can be adapted to fulfil different functionality
• Operational temperature range: 0- 50 degrees Celsius (-20 to +70 on request)
• Dimensions: Eurocard format each module (100 * 160 * 20 mm).
