MHV/24 High-Voltage Scanning Card
MHV/24 Specifications
Note:
These specifications are subject to change without notice.
Number of Inputs:
24 differential; programmable by channel for any input range
Input Connectors:
Screw Terminal.
Voltage Range, Accuracy and Resolution:
Range is based on maximum peak-to-peak signal for AC
volts. Accuracy is based on AC voltages where the frequency of the input signal is an integer
multiple of the AC line cycle
±
1.0%, and with line-cycle integration enabled.

Maximum Common Mode Voltage:
500 VDC or AC peak. Specified for coupling impedance > 30
MOhm, and common mode frequency < 60 Hz. Maximum 700 VDC or AC peak before
equipment damage occurs. Maximum 325 VDC or AC peak if used in the same system with the
MTC/24 scanning module.
Maximum Normal Mode Voltage:
500 VDC or AC peak.
Common Mode Rejection:
100 dB typical.
Maximum Allowable Input:
400 VDC.
Channel to Power Ground Isolation:
500 V peak.
Channel to Channel Isolation:
500 V peak. Maximum 325 VDC or AC peak if used in the same
system with the MTC/24 scanning module.
MHV/24 Description
The MHV/24 high-voltage scanning card contains 24 differential input channels and can measure
analog input signals on any one of the following three programmable voltage ranges: ±2.5V, ±25V,
and ±250V.
