Plug-in relay module for safety controllers

10 August 2014

With the new MSI-EM-4RO relay extension module for the MSI 200 safety controller, users can control multiple devices via potential-free output contacts.

Most modern safety sensors and active opto-electronic protective devices (AOPDs) are equipped with semiconductor outputs today. With such electronic safety-related switching outputs (OSSDs), high voltages in excess of 24 volts cannot be connected, however, and they are not suitable for controlling devices with high power consumption, e.g., contactors, locking devices, pumps and motors.

In such cases, the new MSI-EM-4RO extension module with its four, one-channel or two, two-channel relay outputs helps out. At a maximum switching voltage of 250Vac/dc, it delivers high switching power in a rugged and compact design with housing width of 22mm. Four, freely configurable message outputs indicate operating states of the total system.

The extension modules are simply connected to the base module (MSI 200 safety controller) on the DIN rail by means of mounting rail connectors. The system satisfies the requirements for Performance Level PL e in accordance with EN ISO 13849-1 and SILCL 3 in accordance with EN IEC 62061.

Also new from Leuze is the CR 50 miniaturized CCD scanner, specially designed for integration into medical instruments for automating bar code readings in analysis technology.

The CR 50 is simply connected via a 12-pin connector located on the circuit board. The bar code readers with a scanning rate of 330 scans per second are suitable for all common codes with modulus sizes from 127 to 500um – for example, for readings on samples, reagents, racks or carousels.

With the Sensor Studio PC software from Leuze electronic, the devices can be easily configured via a USB or RS232 interface.
