Belden extends the LioN-Link system from Lumberg Automation™

8/8/2011

New I/O module for safety applications

Belden has brought out a new I/O module in its Lumberg Automation™ range specifically for the decentralized Fieldbus system LioN-Link. The module (0942 UEM 612) fulfills protection class requirements IP67 and has four digital M12 slots with a higher limit on the output voltage permitting 2A per line and 6A in total. These outputs are designed for safety-related applications up to performance level D (as defined in the new Machinery Directive) making this I/O module particularly suitable for failsafe control of actuators or - following a complete switch-off of the 24V output power supply - reliable emergency OFF functions. Your terminal equipment can be connected directly to the I/O module, so there is no need for terminal boxes, which are comparatively expensive and complicated to install. This makes it possible to implement cost-effective safety solutions that can be used, for example, in mechanical engineering applications or in the assembly and handling sector.

Depending on the selected LioN-Link bus coupler, this I/O module can be used in Profinet, Profibus, DeviceNet or CANopen networks. Setting up the modules is practically foolproof, because LioN-Link systems do not use slave address assignments and also do not require terminating resistors. The sturdy housing is made of polybutylenterephthalat (PBT), measures 182.4 x 30 x 28.4 mm (L x W x H) and weighs only 200 g. The module's other features include a temperature range of 10o to +60oC, high vibration and shock resistance plus a power supply configured for a voltage range of 19 to 30V DC.

By introducing this new I/O module Belden has further extended the application range of the decentralized field bus system LioN-Link from Lumberg Automation™. As product manager Robert Strehmann says: "Safety-related outputs can now be switched off directly in the field without the need for an additional terminal box. Moreover, installing these modules saves users even more time and money, because - unlike comparable I/O systems - they are wired up using only standard products."
