More I/O's on the new Pluto B46-6 Safety PLC

Benefits include

• Lower cost per I/O
• It is possible to build larger systems
  32 B46 Pluto's on the same bus = 32 x 46 I/O
• Complete machine control now made easier

The Pluto B46-6, is the most powerful safety PLC yet, but with a width of just 90mm. It has been developed by the need for a compact safety PLC with more built-in I/O’s. The B46-6 has a total of 46 I/O’s, 6 of which are individual safe outputs. Also, 16 I/O’s can be used as either inputs or outputs and there are 24 inputs designated for safety and other devices. Programming is via the intuitive Pluto Manager software and is based on ladder logic, making Pluto suitable for both safety monitoring and control of smaller machines. An operating panel (HMI) can be connected directly to the serial interface or to the safety Can-Bus.

Gateways for Pluto PLC to major bus-systems

Jokab Safety AB has released 3 new Gateways for bi-directional communication between the Pluto safety PLC system and other field bus systems. The supported protocols are Profibus-DP, DeviceNet and CANopen. This enables the customer to choose their machine safety solution from Jokab Safety independent from what higher level bus-system they use for the standard machine control. Gateways for Ethernet are also under development and are expected to be released during 2007.
