Bedrock Automation provides the options listed below for connecting OSA

to the Bedrock Secure OSA Remote via a user-provided cable or the Bedrock
Universal Cable. See Appendix B for pin out information and wiring diagrams.
See Appendix C for field wiring requirements.

The Bedrock Universal Cable is available as an accessory for connecting the OSA
Remote to field devices. The cable is available in three fixed lengths as well as a
custom length as follows:
•
1 meter

3 meters

5 meters
•
the custom length cable is available in increments of one meter up to
a maximum length of 30 meters.
See Appendix A, “Part Numbers” for information on ordering the Bedrock
Universal Cable.
Bedrock UTAs
Bedrock Universal Termination Assemblies (UTAs) are DIN rail mounted screw
terminals that simplify connections between OSA Remotes and field devices.
The Bedrock Dual-head Universal Cable is used to make the connection
between an OSA Remote and a UTA. The dual-head cable, like the universal
cable, is available in lengths of 1, 3, and, 5 meters. It is also available in a custom
length.
See the
Bedrock UTA User Manual
for information on the Bedrock UTAs and
the dual-head universal cable.

other devices that are capable of serial communication using the RS-232,
RS-485, or RS-422 protocols. The Bedrock Universal Serial Communication
Cable is available as an option for connecting the OSA Remote to other devices
via the serial port.
