The new PB4 for the ReefKeeper controllers has been reworked to allow the non-relay channels the ability to control low-wattage items. In the past with the older solid-state channels controlling low power consuming products can be un-reliable. Digital Aquatics has implemented a snubber circuit into channels 2 and 3 to make them reliable.
Channels 1 and 4 are relay controlled and can control up to 8 amps per outlet, where channels 2 & 3 are controller by a solid state snubber circuit allowing up to 3 amps per outlet. With any electrical item safety is number one, and Digital Aquatics includes a 15 amp circuit breaker that can be reset to prevent any trouble.

Necessary Interface By Ken on 6/22/2016Ken would recommend this product to a friendA bit pricy for only four outlets but otherwise works well.
Works as described By Jeremy on 5/23/2016Jeremy would recommend this product to a friendEasy to hook up and program. I wish they had a bigger power bar though. $100 a pop adds up
Not so sure about this one.... By CKF on 2/3/2016CKF would recommend this product to a friendI just got a reply back from Digital Aquatics support that said "All pb4's have the snubber circuitry in them." This product's description is implying that this is a recent development. Apparently it is not.
Ask a question
The PB4 second will count as an additional module. Feel free to let us know if you have any further questions.
The ReefKeeper Lite can handle up to 4 modules of any type. If 3 of those modules are PB4 Powerbars and one module is the SL1 then that is totally fine and will work. The only limit is 4 modules total, the iTemp probe, and head unit do not count against the module limit but any others like PB4’s, SL1, SLX, MLC, etc are all modules that will count against the limit.
The ReefKeeper Powerbars will need to be attached to either a ReefKeeper Lite, or ReefKeeper Elite to function properly.
