Product Description

The X20AP3121 is one of the modules in the X20 series by B&R Automation and is well-built to provide solutions to energy measurement and monitoring applications in the industrial environment. This module is designed for a three-phase power system and comes with several enhancements for better and consistent performance.

The X20AP3121 contains status indicators that give information on the I/O function per channel, the status of the unit, and the status of the module. This makes it easy to monitor the system and in case of any fault, it can be easily identified and corrected. The run/error of a module is signalled by both an LED and software making it a more effective diagnostic tool. Another important feature of this module is the low power consumption with the bus power of 0. 45 W for revisions greater than D0 and an I/O power consumption of 40 mW internally. This makes the module efficient in energy consumption thereby making it suitable for use in a continuous manner. The unit is safe to use, thanks to isolation voltages tested at 5500 VDC for 1 minute between inputs to the bus/I/O power supply, making it immune to high voltage transient conditions. Voltage inputs of the module have been provided with a high input impedance of 1. 68 Mohm and are rated for a nominal voltage of 480 VAC between phases and 277 VAC between phase and neutral.

The present input types of this module have four AC inputs with a nominal current of 1 A and the possibility to sustain an overload current of 8 times the nominal for 0. 5 seconds. This strong design makes it possible to protect the module from damage due to transient currents. The measurement resolution of this model is very high, with an Urms precision of ~0. 65% and an active energy measurement precision per phase and a total of ~0. 45%. This is very useful in applications that demand a certain level of power usage and efficiency parameters to be measured. The product is available at Wake Industrial with a one-year warranty period.
