Turck instrumentation enclosures

Turck’s BL20 motor starter economy module utilises SWIRE technology to provide daisy-chain connection from a single I/O slice to each motor starter via a ribbon cable.

SWIRE technology provides the benefit of plug-and-play connection, eliminating the labour required to hardwire motor starters to digital output points and auxiliary contacts back to digital inputs. By using this connection technology, it is now possible to control up to 48 motor starters on a single fieldbus node.

The BL20 motor starter module allows three-phase motor control to be connected to the same rack as standard I/O. In addition, with the SWIRE connection, motor starters can be mounted on separate DIN rails within the same panel — pairing the flexibility of standard motor starters with the advantages of fieldbus control.

The BL20 motor starter module is available in sizes ranging from 0.08 to 20 hp, both direct and reversing, for use on DeviceNet, Profibus, CANopen, ethernet/IP and Modbus TCP/IP networks with both standard and programmable gateways. Trip indication may also be added to any motor starter. The BL20 motor starter module complies with industrial switchgears standards IEC/EN 60947-4-1 and carries an IP20 environmental protection rating.

The BL20 motor starter module with SWIRE technology consists of a gateway, base modules and electronic modules. I/O modules are configured independently from the fieldbus protocol and up to 72 I/O modules may be connected to a gateway, facilitating systems that may include up to 1152 digital I/O points or 288 analog channels.
