TUC/RTU Controller Boards - RTU-17
RTU-17 CONTROLLER - ( OE310)
The RTU-17 Controller is typically used to control a Constant
Volume Air Handler Unit. This RTU-17 has seven onboard relays,
eight analog inputs, and two analog outputs. The total I/O on this
board sums to seventeen, hence the -17. The RTU-17 Controller
has application-specifi c software that was written for the WCC II
system, but this software also works with the new WCC III system.
There are currently no expansion boards for the RTU-17 that will
work with the application software for the WCC III system.
Examples of older custom software for the RTU-17 Controllers are
listed below:
