931N-A221

The 931N-A221 analog signal converter is a Nano signal conditioning device from Allen-Bradley/Rockwell Automation. It comes with a space-saving 6-millimeter housing, easy DIP switch configuration, and angled terminals for easy wiring. Some of the functions of this device are the isolation, signal conversion, and signal amplification functions. This analog signal converter is UL/CSA, CE, and ATEX certified to meet industrial standards. The common measurement instruments that interface with this signal conditioner are a temperature sensor, thermocouples, speed sensors, and load cells. The 931N-A221 analog signal converter is a standard signal converter with isolation powered by 24 Volts DC voltage and it is compatible with the power bus DIN system. The 931N-A221 signal conditioning device converts analog current and voltage signals while providing 3-way galvanic isolation between the input, output, and power supply.

The 931N-A221 converter's isolation facilities eliminate ground loop and noise-related errors to provide reliable and accurate signals. The input and output signals are electrically separated from each other and decoupled. Its Pollution Degree rating is Pollution Degree 2, its surge voltage category is Category II, and its environmental protection degree is IP 20. The 931N-A221 signal conditioner improves the signal quality of the process measurements between the control system and the field device. It galvanically isolates the signal via transformer coupling. It attempts to pick up the signal accurately and convert it into a higher level of electrical signals for transmission purposes. This analog signal converter can be used in a wide variety of industrial applications such as food and beverage production and steel production. It can be used to take critical process measurements such as pressure, speed, frequency, and voltage measurements on devices that are exposed to harsh environmental conditions in continuous production systems. It also provides a cost-effective design to convert current signals to a control system or PLC.
