Pluto safety PLC‘s
to supervise safety devices
to save on inputs!
Most safety devices on the market can be connected directly
to Pluto units. By using dynamic signals with sensors from ABB
Jokab Safety only one input is needed to achieve the highest
level of safety, compared to two inputs for other manufacturers'
PLCs. It is also possible to connect up to 10 sensors in series to
a single input on Pluto and still achieve the highest level of safety.
For example non-contact Eden sensors, Spot light beams and
Tina emergency stop buttons can all be connected in series to a
single Pluto input. Even mechanical switches can be connected
to the 'dynamic' safety circuit using ABB Jokab Safety's various
Tina adapters. Pluto also has IO connections that can be used as
both inputs and outputs.

IO connections
Pluto has IO connections that can be used in three ways:
• input
• output
• both input and output at the same time
(e.g. for a reset button with lamp indication)
