TURCK’s piconet PROFIBUS stations are compact rugged stations designed for machine mounting. These stations allow easy connection of standard I/O devices such as sensors, limit switches, valves and pilot lights to a PROFIBUS network, typically without a protective enclosure. This is made possible by epoxy-filled station housings, all-metal connectors and visible rotary address switches, among other things.

piconet‘s small size sets them apart from other stations. piconet stations are the smallest rugged I/O modules available, with a standard housing footprint of 30 x 175 mm. They are also available with picofast ® (M8) connectors for I/O, making them ideally suited for small-space applications.

Mechanical Specifications

TURCK DeviceNet piconet stations are designed to be mounted directly on machines and work cells with no separate enclosure or housing necessary. Epoxy-filled housing creates a durable station that allows it to be mounted in most industrial environments. Detailed environmental specifications include:

• Housing material: Glass filled nylon
• Connector material: Nickel-plated brass
• Protection level: NEMA 1,3,4,12,13; IEC IP 67
• Operating temperature: 0 to 55°C

piconet combines the rugged connectorized concept of TURCK’s AIM™ stations with the modular I/O concept of the BL20 and BL67 systems. piconet stations are IP 67 rated and designed to be mounted directly on the machine with no need for a separate enclosure. Like the BL (BL20, BL67) systems, piconet consists of a gateway with connected I/O modules, but instead of connecting the I/O to a fixed backplane, piconet uses a distributed fiber-optic ring to communicate between the gateway and I/O.

piconet stations are available as stand alone units for DeviceNet™, PROFIBUS ®-DP and CANopen systems; this section focuses on piconet subnetwork systems. Subnetwork systems offer a very flexible approach to connectorized I/O, while allowing individual stations to be mounted as close as possible to I/O devices.

Up to 255 extension modules may be connected to one gateway, with no more than 15 m of fiber-optic cable between each module.
