ISOBLOCK C-4C (10V)

IsoBlock C Specification Sheet for Verivolt Galvanic-Isolated Module for Sensor Isolation, Fuel-Cell and Battery Monitoring OVERVIEW 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 four separate isolated channels, each of which can be connected to separate measurement sources while providing a range of functional coverage up to 30V. 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 (of reading) ±0.2% Bandwidth (-3dB point) DC – 100kHz (custom up to 1MHz) Integrated channel noise (Referenced to output) < 1 mV Input-Output non-linearity < 80 ppm Differential input dynamic range per channel ±2V, ±5V, ±10V, ±15V ±30V Channel to channel isolation ± 1800V Working Voltage ± 5000V Surge Voltage Isolation voltage from primary side to secondary side ± 1800V Working Voltage ± 5000V Surge Voltage Gain temperature drift ±50 ppm/°C Max total phase shift at 60Hz < 0.05° Max Input delay < 2.8 μs Common mode rejection 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. 8V to 28V Output type Differential pair Output Offset Voltage < ±750μV Differential Input impedance Output impedance > 2 GΩ 50 Ω MERCHANICAL Mounting Type DIN Rail Connectivity (Connector for power and signals) Weight The IsoBlock module is designed to isolate a bank of differential unipolar input signals, while selectively removing their highvoltage common mode. With four discrete channels per IsoBlock module, the device features channel-to-channel isolation as well as a channel-to-ground isolation, rated at 1800V. Each input’s dynamic range is set to match one of seven standard values, or may be customized to specification, upon request. 108 dB at DC 95 dB at 50kHz Power Supply Voltage Outer Dimensions HARDWARE DESCRIPTION Spring Cage DIN Rail Mounting the Sensor Verivolt’s IsoBlock variable voltage monitoring module comes pre-assembled with a housing allowing for users to quickly and securely mount the device to industry-standard DIN rail guides. The flexible clip on the reverse of the unit’s housing latches to the parallel rails of the DIN, affording the IsoBlock exceptional modularity and ease of deployment within integrated Systems. 4.3” x 3.4” x 2.4” 218 g (7.7 oz) ENVIORNMENT Operating temperature – 25 to 70 °C Storage temperature – 40 to 80 °C 650 Washington St, San Francisco, CA 94111 (708) 374-8658 1 MERCHANICAL DIMENSIONS HARDWARE CONFIGURATION A.
