Model V250

64-channel VME digital input/output module

Overview

Features:
  • 64 independent channels, each programmable as a digital input or output
  • Open-drain outputs can sink loads up to 200 mA and 40 volts
  • Inductive-load flyback clamping is included
  • Logic-level inputs have programmable thresholds from 0 to +10 volts
  • In/Out resistor pull-ups are programmable from 0 to +10 volts
  • Programmable input debounce allows direct interface to switches and relay contacts
  • Can directly drive LEDs, SSRs, and FET gates
  • Clearly labeled dipswitches set VME address; no jumpers, headers, or trimpots
Description:

The V250 is a single-wide, 6U VME module that provides 64 non-isolated channels of digital input/output. Each 16-channel bank shares programmable pull-ups and input thresholds with a range of 0 to +10 volts. Open-drain drivers can sink up to 200 milliamps and withstand up to +40 volts. Drivers include flyback clamps, which conduct at +45 volts nominally, to allow low-side drive of relay coils from up to 36 volts. Each channel has a programmable digital debounce with delays of 1 millisecond, 10 milliseconds, and 100 milliseconds.
