PXI simulator modules mimic current loop- based sensors

These modules are aimed at simulating industrial control transceivers, utilising 4–20mA current loops.

Part of an expanding range of PXI simulation modules from Pickering, the 41-765 also enables slew rates to be programmed so that different sensors can be effectively mimicked.

The 41-765 Analog Output/Current Loop Simulators feature multiple output modes, 4–20mA, 0–24mA, +/-24mA, 0-5V, +/-5V, and +/-12mV, which also improve simulation accuracy and versatility. The modules include built-in relays for shorts and opens functionality enabling fault insertion testing on every channel.

Devices can also work in Full Isolation mode to avoid ground loops.

Delivering from 4 up to 16 channels in one PXI slot, the 41-765 modules are the highest density simulators of their type, freeing up PXI or LXI/USB chassis slots for other instrumentation.

The new modules feature an easy-to-use soft front panel. Kernel and VISA drivers are included, and all major programming environments, including C/C++, .NET, Python, LabVIEW and MATLAB, are supported.

Comments Paul Bovingdon, Simulation Product Manager, Pickering Interfaces: “Most simulators are manual hand-held devices. By automating the process, the 41-765 Analog Output/Current Loop Simulator Modules save time and improve accuracy in simulation applications such as Hardware-In-The Loop.

Designed to simulate industrial current loop transceivers in applications such as process instrumentation, PID (Proportional–Integral–Derivative) controllers, SCADA (Supervisory Control and Data Acquisition) systems, and PLCs (Programmable Logic Controllers), the 41-765 modules carry a three-year warranty.

The 41-765 follows the releases earlier this month of thermocouple simulator modules and LVDT/RVDT/Resolver Simulator Modules.

The modules can self-power using the PXI chassis supply or can be powered externally in full isolation mode.

A channel can source or sink, emulating a transmitter or receiver. A PXIe version is available upon customer request. Pickering also provides a full range of compatible cables and breakouts.
