The V230 provides high channel-count data acquisition for dense monitoring applications. The 64 channels are individually programmable for both input range and filtering. The three input ranges slightly exceed ±10 V, ±1 V, and ±100 mV, allowing confident measurements all the way to the end of common signaling ranges. For low frequency applications, the programmable sinc² lowpass filters provide excellent rejection of 50 Hz and 60 Hz harmonics without generating transient overshoots.
From the moment of power-on, with no configuration, the V230 begins scanning all 64 differential input channels and posting the results to VME memory space. Data is presented in real-time as a simple array of 64 values with no handshakes, interrupts, or driver calls required.
Optional built-in self-test provides an on-board voltage source that can be switched into any of the channels for verification, as well as the D9 OpenCal bus to allow verification against external equipment without disconnecting field-wiring connectors.
