Compatibility: VMEbus specification compatible. Double height form factor.
Input Connector Type: Dual 64-pin connectors – DIN 41612 I/O Organization: Eight input ports; eight bits wide. Addressable to any address within short supervisory and/or short nonprivileged I/O map. Control and Status Register (CSR) address is independently selectable.
Addressing Scheme: Eight ports individually addressable on 8-, 16-, or 32-bit boundaries. One CSR addressable on an 8-bit boundary. Thirteen jumpers provide unlimited short data I/O address map selection.
Differential Signal Input Characteristics: Common-Mode Input Voltage Range: -30 to +66V. Input sensitivity of ± 100mV over common-mode range of -7 to +12V. High input impedance (33kΩ ).
Single-Ended Signal Input Characteristics: High input impedance (33kΩ ). Threshold accuracy of 1 percent over entire 66V range (typical). Refer to Figure 3 for typical single-ended signal conditioning electronics.
Signal Conditioning Input Filter Terminator Option: The board may be ordered with an input signal filter circuit. For differential inputs, this circuit consists of a series resistor and capacitor
