The Pluto ASi Safety PLC from Jokab Safety is available with Sensorplex . The Pluto ASi Safety PLC has features that include four failsafe inputs, four configurable digital I/O for failsafe analogue inputs, failsafe dynamic failsafe input and four failsafe outputs.
The Pluto ASi Safety PLC is a new safety programmable control unit which can work on the ASi bus network and has a combination of three functions. Pluto ASi can be configured to be master/monitor, monitor/slave or monitor only. In master/monitor mode, the Pluto controls the ASi bus and reads the I/O in the slave units. All the I/O can be used in the Pluto manager programme.
In monitor mode, the Pluto listens to the bus and an external master controls the safety inputs and outputs in an external PLC. When set for monitor/slave the unit is the same as a monitor with the Pluto acting as a slave to the ASi master. At the same time Pluto Asi can connect to other Pluto PLC units through the Safebus, and other AS-i networks can be incorporated into the programme. This also allows safety devices that are not on the ASi bus to be included into the safety system.
Pluto Asi includes three dynamic pulses that provide a range of opportunities when selecting safety devices in the field. Jokab Safety products can work with the dynamic pulse and allow the user to meet Category 4/SIL 3 when connecting devices in series. Gateways, HMIs and encoders can be connected to the Pluto on the Safebus. The Pluto manager software can be downloaded from Jokab's website. The software includes all manuals and 27 safety function blocks which cover all applications when using devices for emergency stop, two-hand control, foot switches, light curtains, safety switches, mats and bumpers.
