Three I/O control modes: static, strobe and handshake
The Keysight N2263A is a 32-bit digital I/O module. It provides 32-bit bi-directional lines and three handshake and control lines. The 32-bit I/O lines are TTL compatible input/output, or TTL compatible input and open collector output up to 42V. A Zener diode is used in each channel for input voltage over-protection (>42VDc), including ESD protection. Each I/O line can sink up to 0.6 A to control external devices including:
High voltage/high current relays;
Microwave relays and attenuators ( 8710xx , 876xx and 849xx);
The polarities of the I/O and handshake lines can be operated in positive or negative logic mode. With the three control lines (PCTL, I/O and PFLG), you can define five handshake modes for communication with peripherals.
