0° C to 50° C, 90% relative humidity. Will
withstand shock and vibration of normal
shipping and handling of laboratory equipment.
Digital
Input Card 730011
Back
to 730
The Model 730011
Digital Input card provides 26 isolated digital inputs to the System
730. Handshake signals provide synchronization with the user device.
Optic coupling is used to isolate all inputs and outputs from system
ground.
STROBE input
and HOLD output signals are provided to handshake with the user
device.
HOLD is an output signal used to indicate that a read-cycle is in
progress.
Multiple digital
input cards may be installed to input data words wider than 26 bits.
Cards are synchronized by means of a single wire ORed signal.
