VXIBus - V387 128-channel Discrete Input/Output View Datasheet Request Ordering Information     ABOUT V387 The V387 is a single-width, C-size, register-based, VXIbus module that contains up to 128 channels of digital input and/or output (TTL option). The module is configurable on a 32-channel basis through four interchangeable mezzanine cards, which are available in an assortment of I/O options. Two non-isolated versions are available for bidirectional transfers: 32-channels, single-ended TTL; and 16-channel, differential (RS-422 signal levels). Seven isolated input voltage options (TTL, 12 V dc, 16 V dc, 24 V dc, 28 V dc, 48 V dc and 120 V ac) are also available. Input isolation is achieved by using LED/photo-transistor optical isolators. Each option has 16 circuits with identical input voltage ratings. Each circuit draws more than 5 mA, but less than 15 mA. The logic convention is such that a contact closure (voltage present) is interpreted as a logical "1". Each input is conditioned by filtering after the optical isolator. The filter time constant is programmable from 5 µs to over 1 s in 64 steps.
