N2264A Multifunction Module
The Agilent N2264A multifunction module combines a GP relay
function, a high-current GP relay function, and a digital input/output
function on a single module. It consists of:
•
12-Channel GP relays (non-latching Form-A)
•
3-Channel High-current GP relays (non-latching Form-A), capable of
switching up to 5 amps.
•
16-bit Digital I/O
The parallel switching feature makes the module well suited for high
speed switching applications. Any 10 of the 15 GP relays on the N2264A
can be closed all at once (parallel switching). Additional information
about parallel switching is given on page 84.
Five handshaking modes are available for the digital I/O function. The
handshaking modes are described beginning on page 98. Handshaking
uses up to three control lines:
•
Peripheral Control (PCTL)
•
I/O direction (I/O)
•
Peripheral Flag (PFLG)
Port and bit numbering is show in the table below. Note that the ports
are numbered differently if you are using the 3488 System mode.
Specifications for the N2264A are given on page 310.
