Agilent / HP / Keysight 34952A

This module for the 34980A Multifunction Switch/Measure Unit allows great flexibility for a variety of sense and control applications.

It combines four 8bit channels of digital input and output, a 100KHz gated totalizer, and two ±12V analog outputs all on a single earth referenced module.

The digital inputs and totalizer input may be included in a scan.

Alarm limits for the digital and event counter inputs are evaluated continuously, capturing and logging alarm conditions even between scans.

The digital I/Os support TTL levels.

These channels can be used with an external power supply to control external devices or to sense limit switch and digital bus status.

There are no complex handshake modes.
