Chapter 2 Installing the 1756-HYD02 Module
Choosing the
Extended-Depth Housing There are two housing options you must consider when wiring your
ControlLogix Hydraulic Servo module. When you order an RTB for your I/O
module, you receive a standard-depth housing with the RTB. If your
application uses heavy gauge wiring, you can order an extended-depth housing.
This housing does not come with an RTB.
You can use one of the housings listed below:
The figure below shows the difference, in terms of capacity, between the
housing options.
This housing: should be used with this RTB: and allows up to this
capacity of wires:
1756-TBCH Cage clamp 336 sq. mm
1756-TBS6H Spring clamp
1756-TBE Any RTB using heavy gauge wiring 628 sq. mm
IMPORTANT
The housings shown are used with a spring clamp RTB, but the
capacity for each remains the same regardless of RTB type.
