The Isolated Multi-channel DAQ for Multi-cell Stack Systems is a compact retro fit unit designed and developed for installation in the fuel-cell and for similar systems. The system facilitates monitoring of voltage across all proton exchange membranes with programmable alarms, temperature profile of stack, power monitoring, control of hydrogen flow through the stack etc. The system also offers touch screen based local GUI along with PC based control interface. The system can also be extended over Modbus RTU to most of the mainstream SCADA software. The equipment shall be an import substitute to a high density programmable modular DAQ system.

Potential application areas of the system are:

1. Monitoring and control of fuel cell.
2. Lithium ion battery cell voltage monitoring during charging/discharging.
3. Educational institutions, R&D organizations.

1. Compact standalone system specifically designed for Fuel-Cell stack monitoring and control.
2. Retrofit assembly.
3. Standard high density DB connectors for ease of use.
4. Facilitates monitoring and control of auxiliary parameters.
5. System also facilitates programmable trip alarms.

This standalone system provides 30 isolated analog input channels for monitoring of proton membrane voltages and power monitoring and control by controlling hydrogen flow rate. The system also provides acquisition channels for 8 thermocouple points for fuel cell stack temperature monitoring at various points. The system has inbuilt discreet input/output control for external hydrogen LEL trip sensors and alarms. The data is monitored on a touchscreen enabled GUI locally as well as a PC interface software. This entire system is packed in a retrofit unit of dimensions 8 X 8 X 2 (L x W x H in inches).
