PXI Analog Output / Current Loop Simulators

These modules are aimed at simulating industrial control transceivers, utilizing 4–20mA current loops. The modules include built-in relays for shorts and opens functionality enabling fault insertion testing on every channel and also enable slew rates to be programmed so that different sensors can be effectively mimicked. Delivering from 4 up to 16 channels in one PXI slot, the modules are the highest density simulators of their type, freeing up PXI or LXI/USB chassis slots for other instrumentation.

Designed to Test Industrial Current Loop Transceivers in applications such as: 

• Process Instrumentation 
• PID (Proportional–Integral–Derivative) Controllers 
• SCADA (Supervisory Control and Data Acquisition) systems 
• PLCs (Programmable Logic Controllers)
