FOXBORO FBM242 P0916TA Discrete Output Module

Overview

The FBM242 Discrete Output Module is designed to interface electrical output signals from a control processor to field devices in industrial automation systems. It features 16 discrete output channels, which can handle up to 2.25 A per channel at voltages ranging from 15 V dc to 240 V ac. The module provides full isolation for each channel, ensuring reliable operation in harsh environments. Additionally, it includes features like ladder logic support and a Fail-Safe Configuration option for the outputs.
