HP E1459A 64-Channel Isolated Digital Input/Interrupt

[ Summary ][ Features ][ Specifications ][ Key Literature ][ Ordering ][ Assistance ][ Related ]
The HP E1459A 64-Channel Isolated Digital Input/Interrupt is a C - size, 1-slot, register-based VXI module. It is used to sense dc levels and edge transitions up to 48 Vdc. All inputs are optically isolated to withstand up to 125 V rms or Vdc. Plus, using the module's built-in 5 V supply with 9.4 kOmega effective pull-up resistance, you can detect whether external switches are open or closed.

The debounce feature is programmable for periods of 16 µs to 1074 s in binary increments. Channel groups 1 to 32 and 33 to 64 can each have a unique programmed debounce period.

Each word (16-bit/channel) has strobe in, ready for data, and interrupt out. Strobe-in lines can be connected in parallel for 32- or 64-bit transfers.
