features, specifications, and applications.

Chapter 2 Installation

Describes how to install a switch module into a PXI chassis. For

software library and utilities installation, please refer to the

Software Users’ Guide.

Chapter 3 Signal Connection

operation instructions.

Introduction • 1

Introduction

JYTEK PXI-67921 is a relay multiplexer module which consists of 24 2-wire

relays (DPDT, 2 Form C). PXI-67921 provides 48x1 1-wire and 24x1 2-wire

and 12x1 4-wire configurations and typically connects one instrument, such

as a DMM, a digitizer or a signal source, with many points which need

measurement or excitation.

Relays of PXI-67921 can be updated by either direct-update mode or auto-

scan mode. The latter mode supports scanlist of 1k-sample for

deterministic scanning.

PXI trigger functions are fully supported and software programmable. The

multiple switch modules can be synchronized and triggered without additional

field wiring.

For safety critical applications, PXI-67921 module can switch to the preset

state by either asserting emergency shutdown manually, or watchdog timer

overflow event.
