Cell voltage monitor kit for H2 fuel-cell stack research and applications can be used to prevent damage to individual cells, to monitor lifetime conditions, and to ensure optimal working conditions in applications.

Cell voltage monitor kits are complete sets ready to use in your special application. They can be connected directly to a PC with USB interface or to a PLC using RS485 bus.

Kits are based on CVM32A module, which is designed as a costeffective solution mainly for hydrogen fuel cell applications. For research, testing, automotive and precision applications see Tevomet TV16.

Cell Voltage Monitor CVM-Ext32A Includes:


• 1x CVM32A
• 2x XC2 bus plug
• 2x IDC plug for channels
• 4x spacers
• 1x enclosure extension

Features:


• 32 channels per one CVM32A module
• Basic channel voltage range ±1.5 V
• Maximum voltage span of channels on one module is 34 V
• Multiple modules can be chained to get more channels
• Resolution 1 mV (12-bit)
• Input impedance > 100 MΩ

• Cell connection via 34-pin IDC connectors
• Compatible with all other Kolibrik.net modules (KMS, DIN-rail I/O modules, Tevomet, ...), communication bus XC2/RS485
• IO (1x digital output, 1x digital input)

Applications:


• H2 fuel-cell tests stands
• H2 fuel-cell application monitoring
• Control systems

System Modularity:


• Cell voltage monitoring system consists of:

• One power and communication module KMS-PWR
• Number of 32-channel modules CVM32A, depending on number of channels needed

• There are kits available with 64, or 160 channels, which can be extended by an extension kit with 32 channels. Maximum length after extension for those kits is 10 modules with total of 320 channels.
