RSL 400 series safety laser scanner

May 2015 IS & Ex

Leuze Electronic’s latest RSL 400 series safety laser scanner is available in 16 device versions, with operating ranges of up to 8,25 metres, which can be configured via Bluetooth and Ethernet TCP/IP.

The devices’ large scanning angle of 270° is especially advantageous for example in the case of mounting on corners or edges for front and side guarding, and can, depending on the application, replace a second laser scanner.

With two completely autonomous protective functions, two pairs of safety switching outputs and nine other configurable contacts, the RSL 430 variant is a device that solves two protection tasks simultaneously.

All devices demonstrate high resolution (rod test) in addition to a high insensitivity to dust due to the fast scanning rate. A large plain-text display, with integrated electronic spirit level, ensures simple alignment when mounting the connector unit. The connector unit contains the entire cable management, and forms the mechanical and electrical basis of the devices.

The scanner itself can be removed at any time using standard tools and retrofitted with other RSL 400 devices without the need for realignment, readjustment or lengthy configuration. “This is an important advantage in terms of ease of maintenance and repair,” says Countapulse Controls managing director, Gerry Bryant.

The scanners feature simple integration in machine control applications thanks to an eight-pin M12 connection. Any type of protective/warning field contours (1 field pair/quad) can be accommodated.

Basic functions such as automatic start/restart, start/restart interlock (RES), contactor monitoring (EDM) can be selected. Optimum handling is ensured by means of separate intelligent connection unit and a large, plain-text display with integrated electronic spirit level. An Ethernet TCP/IP and Bluetooth interface is available for simple and convenient configuration and diagnosis.

The RSL 420 safety laser scanners expand the monitoring function to include flexible safety requirements adapted to the automation process. Two independent protective functions and OSSD pairs with individual response time make the RSL 430 safety laser scanner interesting for many area safeguarding and access guarding applications with separate machine parts.

Advantages include two independent protective functions and OSSD pairs with a monitored changeover of ten field pairs/quads each, nine configurable signal outputs, a safe internal switch-off delay and configurable data output with UDP.
