Belden (www.belden.com) has announced that it adds a new I/O module to its Lumberg Automation range specifically designed for the decentralized Fieldbus system LioN-Link. Employing protection class requirements IP67, the new 0942 UEM 612 I/O module comprises four digital M12 slots with a higher output voltage limit that allows 2A per line and 6A in total.
Designed for safety-related applications up to level D, this I/O module is suitable for actuators’ failsafe control, or “following a complete switch-off of the 24V output power supply” reliable emergency OFF functions.
The terminal equipment can be linked directly to the I/O module. Thus, terminal boxes, which are expensive and complex to install, are no longer required, making it possible to employ cost-effective safety solutions for mechanical engineering applications and in the assembly and handling sector.
The I/O module can be utilized in Profibus, Profinet, CANopen or DeviceNet networks, depending on the chosen LioN-Link bus coupler. Furthermore, LioN-Link systems do not require terminating resistors and do not use slave address assignments.
Weighing only 200 g and measuring 182.4 x 30 x 28.4 mm, this module also features a high vibration, a shock resistance with 19V to 30V DC power supply, and a temperature range between 10 degree Celsius and +60 degree Celsius.
“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,” said Robert Strehmann, product manager.
