Remote I/O Analog - do you use "blue hose" for analog I/O?

Many Allen-Bradley PLC-5 processors are now being upgraded to use newer ControlLogix processors while still keeping in place (at least temporarily) the plant's reliable old "1771" style I/O hardware - and all of its installed wiring.

At the ControlLogix end of the line, a 1756-DHRIO "bridge" module provides a means of connecting the existing cables (known as "blue hose") to the new controller system.

This common situation presents some serious challenges to the maintenance crew especially where the older "1771" style analog input and output modules are involved.

This is such a common arrangement, that each student in our Boot Camp classes will set up a DHRIO module through a series of hands-on exercises on Monday afternoon.
