P300-380A DynamicSignals 32-Channel Single-Ended TTL Input/Output Mezzanine Card

The Kinetic Systems 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 and the switching threshold is approximately one half of the rated input voltage. 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.
