Smart Han® – Smart Ideas in Smart Connectivity

Intelligence at the connection point – that is the idea behind Smart Han®. HARTING combines expertise in reliable connectivity with future-forward technology – in the footprint of the well-established Han-Modular® insert.

HARTING’s Smart Han® approach is to develop solutions in conjunction with leading IIoT thought-leaders, as needs arise, with the goal of making them globally available. Below are case studies of successes developed by HARTING.

The Han-Modular® Mini Switch (US4)

Han-Modular® Mini Switch Module

The Han-Modular® Mini Switch (US4) moves Ethernet switching capability into the connector. An advanced Ethernet and network switch in one, the Mini Switch facilitates the integration of additional Ethernet nodes to make expansion or retrofitting easier than ever. For example, high-resolution cameras used for quality assurance can be incorporated into the network at a point closer to the field – wherever there is a Han® connector installed. Up to four devices can be connected via RJ45 ports.

The Mini Switch module supports Ethernet (10 Mbit/s), Fast Ethernet (100 Mbit/s) and Gigabit Ethernet (1000 Mbit/s). It’s Plug&Play compatible, with surge protection, and its integrated LEDs also provide quick and easy power and network diagnostics.

HARTING’s new Han-Modular® Surge Protection Module

Han-Modular® Surge Protection Module

Proper industrial surge protection often requires separate, external solutions that take up space and are add labour cost to install. HARTING’s new Han-Modular® Surge Protection Module moves that surge protection into the connector, simplifying wiring arrangements. Installation is fast and simple. It will generally be part of the initial connector setup.

The Surge Protection Module protects up to two pairs of balanced signals interfaces with electrical isolation against normative 8/20μs current pulses. The preferred field of application for this module is for protecting analogue signal interfaces for 0/2-10V or 0/4-20mA. The surge energy (5kv Surge per line) is discharged via the earthed hinged frame of the Han-Modular® system.

ID Module and CAN ID Module

ID Modules

Two Smart Han® modules for insertion in Han-Modular® connectors – the ID Module and CAN ID Module – have memory capability for self-identification inside Han®and storing the revision status of drives and their parameters and other technical information. This helps ensure reliable operations, minimized downtime during setup or maintenance, and can even form part of a predictive maintenance program.

In the case of modular machinery with pluggable drives, the ID Module communicates with the control system and can help it recognize reconnection errors before they damage the machinery. The CAN ID Module on a CAN Bus system enables the current configuration of the isochronous drives to be tested and the parameters transmitted to all other drives and the controller.

The machine may only start if the drive is correctly configured. During servicing, drive configuration stored in the CAN ID module is available at the connector periphery, so individual machine elements can be swapped out or repaired faster, since work on a subsystem does not entail starting the entire machine.
