Product Description

In automation systems, B & R Automation output modules such as the ECPA81-21 offer accurate signal transmission for reliable performance. This module is part of the ECP series. It is equipped with 8 channels that boast an output capacity of 0 to 20 mA. This allows the unit to be connected to a variety of automation components and devices since the module can handle varying current demands. It can also accommodate fluctuations in current up to a maximum of 20 mA ensuring consistent performance even in challenging setups prone to surges or current spikes.

This unit is versatile and performs optimally in demanding applications. It features a ~0.1% precision offset at 20 degrees C. This helps to maintain data integrity by ensuring minimal deviations from actual data. The high level of precision makes this module suitable for sensitive applications that require precise control. The unit is also optimized for efficient energy use which improves overall system performance. It has a power consumption of 0.5 W at +8 V, providing an efficient solution with low power demands for automation applications.

The ECPA81-21 features a 12-bit resolution, making it reliable in precision applications that require high accuracy in output levels. It is designed to support a load capacity of 560 degrees C" per channel. This ensures that the module can handle output signals with relatively high resistance loads efficiently. This module ensures precise and reliable analog signal output, making it ideal for controlling automation devices such as actuators and sensors in automation setups. It features a lightweight design that offers a simple installation experience with minimal space requirements. This unit is available from Wake Industrial and comes with a one year warranty.
