Bedrock Secure OSA Remote Overview
Introduction
This document provides reference information for the Bedrock Secure OSA
Remote. This includes descriptions of OSA Remote hardware and software
components, configuration information, communications, and installation.
The OSA Remote is designed to provide remote applications with power,
control, and I/O in a single transportable unit that can be configured and
programmed on a desktop and then mounted at a remote location.
Each OSA Remote provides either ten or twenty universal, secure input/output
channels. Each channel has channel-to-channel and channel-to-ground galvanic
isolation. Each channel on the OSA Remote can be independently configured to
operate in one of several modes. Depending upon the mode selected, OSA
Remote channels can interface to analog inputs and outputs with or without
HART, discrete inputs and outputs, or NAMUR sensors. The available
operating modes are listed in the next section. Additional detail is provided in
“Analog and Discrete Input/Output”.
OSA Remote Offerings
Both ten and twenty channel OSA Remote models are available with a standard
8 GB of flash memory or an optional 32 GB of flash memory. Table 1-1 lists the
available OSA Remote models. Customer-specific OPC UA security keys are
available for all models via a firmware upgrade. See “Customer-specific OPC UA
Security Keys” in “OSA Remote Operation”.
See Appendix A for part numbers for all OSA Remote models.
