3.7 Hardware accessories
The Power Focus concept features a number of accessories that simplify the guidance and follow-up of
performed tightenings. The accessory functions can be set up using ToolsTalk PF or a PF Graph unit.
The benefit of using serial bus-based accessories (I/O bus) is that they can be connected in series, from
accessory to accessory rather than hard wiring each accessory to the Power Focus. This arrangement
increases flexibility and quick installation.
Power Focus uses 24 V DC, 1 A to power the bus, which is also used to power external I/O's. If more
current is needed, the bus must be powered externally. Every device has a 24 V DC input for this
purpose.
I/O Expander enables the connection of several inputs and relays when more
than those built-in are required. There are 8 inputs and 8 relays with the same
functionality as the four built-in I/O's. Each input and relay can be configured
individually.
I/O Expander, sealed
The sealed I/O Expander is designed for more demanding environments than
I/O Expander. It will add eight digital inputs as well as four digital and four
relay outputs to your system.
Indicator Box is a flexible display indicator used together with our Start
handle for indication of status signals from the controller. The box can easily
be connected to the Power Focus with premade cablings.
