Product details
The Pentair 520818 is the serial COM port expansion board for IntelliTouch and EasyTouch automation systems, supplied with a 1 ft cable. It is the genuine Pentair part.
What it gives you
The board installs inside the automation enclosure and adds three four-pin COM ports plus four two-pin terminals. The COM ports take accessories such as an iS10 remote, additional wireless controllers, indoor control panels and ScreenLogic2 protocol adapters. The two-pin terminals are non-powered and are used for communication to IntelliFlo pumps.
Why people fit one
A pool automation system tends to grow. A remote here, a variable speed pump there, then someone wants control from indoors or from a phone, and the connections on the main board run out. Rather than choosing between accessories, the expansion board makes room for the ones you want to run at the same time.
Before you start
Work inside an automation panel means live line voltage nearby. Kill power at the breaker before opening the enclosure, and if you are not comfortable working in there, have a pool technician or electrician fit it.
