The PXI program-controlled simulation module can effectively simulate sensor-based current loops in industrial control applications

 41-765 Analog Output/Current Loop Simulation Module

4–20mA current loop for testing industrial transmitters

On October 31, 2020, in the town of Clarkton-on-Sea, England. Pickering Interfaces, Inc., a leader in the production of signal switching and simulation solutions for Electronic test and verification, today introduced a new product, the 41-765 series of analog output/current loop simulation modules for simulating a 4-20mA current loop. Industrial transmitters. A new addition to Pickering’s family of PXI simulation modules, the 41-765 series can be programmed to set slew rates to efficiently simulate different sensors.

The 41-765 series modules have several different output modes, including 4–20mA, 0–24mA, +/-24mA, 0-5V, +/-5V, and +/-12mV, which are versatile and help improve simulation performance. Accuracy. In addition, this series of modules also includes built-in relays for simulating short and open circuits, with fault injection testing on each channel. Additionally, this series of modules can operate in fully isolated mode to avoid ground loops.

The 41-765 series modules are the highest density of the emulation modules of their kind, occupying only one PXI slot and can provide 4 to 16 channels, saving slot space for PXI or LXI/USB chassis for other instruments. In terms of software, this series of modules all have easy-to-use software panels, including Kernel and VISA drivers, and support all mainstream programming environments, including C/C++, . NET, Python, LabVIEW and MATLAB.

Paul Bovingdon, Simulation Product Manager at Pickering Interfaces, explained the new product: “Most simulation modules are handheld and manually operated devices. The 41-765 Series Analog Output/Current Loop Simulation Modules automate the operation, saving the user time and improve accuracy in simulation applications such as hardware-in-the-loop.”

The 41-765 series modules are suitable for simulating industrial current loop transmitters in a variety of applications, such as processing instruments, PID (proportional-integral-derivative) controllers, SCADA (supervisory control and data acquisition) systems, and PLCs (optional). Programmable logic controller) and other applications. In addition, this series of modules comes with a three-year warranty. In addition, this series of modules can be powered from the PXI chassis power supply or externally in fully isolated mode. Each channel can be set as either out or in, simulating a transmitter or receiver. A PXIe version of this series of modules is also available upon customer request. In addition, Pickering also offers a comprehensive range of matching cables and terminal blocks. For details, see:
