Modules for safety-related applications

摘要

Belden has brought out a new I/O module in its Lumberg Automation range for the decentralised 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 2 A per line and 6A in total. These outputs are designed for safety-related applications up to performance level D making this I/O module suitable for failsafe control of actuators or - following a complete switch-off of the 24V output power supply - reliable emergency shut down functions. Terminal equipment can be connected directly to the I/O module so there is no need for terminal boxes. Depending on the selected LioN-Link bus coupler, the I/O module can be used in Profmet, Profibus, DeviceNet or CANopen networks.
