IsoBlock C Specification Sheet for Verivolt Galvanic-Isolated Module for Sensor Isolation, Fuel-Cell and Battery Monitoring The IsoBlock module has been designed to provide low-cost and high-quality isolated differential voltage measurements along a chain of fuel-cells or batteries. Our innovative modular architecture and isolation techniques allow users to connect multiple IsoBlock modules together serially, facilitating the monitoring of long fuel-cell or battery chains. Each IsoBlock unit hosts eight separate isolated channels, each of which can be connected to separate measurement sources while providing a range of functional coverage up to 1500V. The input of each specific IsoBlock channel has its own isolated reference, and can be configured to suit user needs. All processed signals output from the IsoBlock unit are referenced in respect to the ground channel of the user’s data acquisition system. Verivolt designs its IsoBlock modules with consideration for user flexibility, exceptionally high channel-density and low power consumption. SPECIFICATION Eletrical Accuracy Integrated channel noise (Referenced to output) Input-Output non-linearity Differential input dynamic range per channel HARDWARE DESCRIPTION The IsoBlock module is designed to isolate a bank of differential unipolar input signals, while selectively removing their high-voltage common mode. With eight discrete channels per IsoBlock module, the device features channel-to-channel isolation as well as a channel-to-ground isolation, rated at 1200V. Each input’s dynamic range is set to match one of seven standard values, or may be customized to specification, upon request. Channel to channel isolation ± 1200V Working Voltage ± 3000V Surge Voltage Isolation voltage from primary side to secondary side ± 1200V Working Voltage ± 3000V Surge Voltage Gain temperature drift Max total phase shift at 60Hz The figure above indicates the input, output and power polarity of the IsoBlock module. The IsoBlock module is designed to mount on standard NS-35 or NS-32 DIN rails with minimal preparation, providing users an indispensible monitoring utility with unparalleled flexibility.

MERCHANICAL DIMENSIONS HARDWARE CONFIGURATION A. Securely connect external power source to primary power unit, with respect to line polarity. For proper functioning the power supply should provide between 8V and 28V with at least .5A of current. B. Securely connect wire in the 20-26 AWG range between the source of measurement and an available IsoBlock’s input spring cage terminal. a cable of up to 3”diameter. C. 1) Securely connect wire to the output terminals which correspond to the inputs used in Step 2. 2) Connect the leads from the out- put terminals to the inputs of your data...
