White Paper: Understanding Two-Wire Transmitters and 4-20mA Loops
As the leading analog transmission standard for industrial I/O, the future continues to look bright for the 4-20mA current loop. The current loop's lossless nature, lower-sensitivity to induced noise, live-zero offset, fail-safe operation, easy scalability and abundance of inexpensive compatible devices make it very popular. Loop-powered two-wire transmitters and isolators/splitters which considerably simplify installation and conversion of real world signals (flow, level, temperature, pressure, etc.) into 4-20mA, continue to evolve with modern technologies.
But despite their popularity, two-wire transmitters and 4-20mA loops are often misapplied and many misconceptions exist. This white paper explains the proper way to use and install transmitters in a current loop. You'll also learn how to determine required supply voltages, filter out noise, add fault protection, and compensate for wire resistance.

Managed Product Life-Cycles
Great lengths are taken to accommodate OEM and military customers that demand stable designs with long product life cycles. We design for an expected life cycle of ten years or more through careful selection of parts and the availability of second-source suppliers. When necessary, Acromag has made "lifetime" buys of discontinued parts to ensure we can supply our existing customer base for years into the future. In other cases, Acromag has redesigned boards to maintain form, fit, and functional equivalency.
Extended Temperature Ranges
Most products are available with -40 to 85°C operating ranges. Some carrier cards and FPGA modules are designed for use in conduction-cooled systems.
Extensive Hardware and Software Support
To speed development and deployment of your embedded system, Acromag provides a full line of support products. Termination panels, adapters and cables simplify field I/O connections. C libraries with source code provide example function routines quickly get you interfacing with your I/O boards.
White Paper: FPGAs for Speed and Flexibility
Learn about FPGA-based system design for embedded computing I/O signal processing applications. This white paper discusses how Advanced Xilinx Virtex and Altera Stratix FPGAs make use of multiple digital clock managers and simultaneous parallel execution to rapidly compute a set of integrated processes including FFT, SERDES, FIFO management, logic sequencing, DDR control, and more. With integrated I/O and enablers such as a soft CPU and IP cores, plus tools such as Xilinx ISE, Altera Quartus, SimuLink, and MathLab; the FPGA can process logic much faster than any real-time system with less effort than ever before.
