Product Description

Performance characteristics
 

SLC-AD safety light grid is designed with the most advanced international functional safety concepts and technologies to provide customers with a safe workplace, with the following advantages:
 

• TYPE4 security level

SLC-AD complies with ISO13849-1, Cat.4 category, and reaches PLe safety level; Complies with IEC/EN62061 and IEC/EN61508SIL3 safety levels;
Complies with Type4 safety based on EN/IEC61496-1/-2 and GB/T19436-1/-2.
 

• No blind zone design

Suitable for structurally constrained applications,it's easy to build comprehensive blind zone protection area when applying multiple L or U-shaped combinations.
 

• Multiple sets of cascades

Three sets of light curtains cascade combinations can be realized. The cascade combination effectively prevents mutual optical interference between multiple sets of light curtains
 

• Optical/line synchronization optional design

SLC-AD can realize optical or line synchronization optionally, and different synchronization methods can be selected according to the field situation.
 

• Redundant OSSD output with self-diagnostics

Dual independent redundant outputs are used,drive safety relays or safety PLC to improve the safety performance of the system
 

• Multiple optional setting functions

SLC-AD safety light curtain can be easily configured with functions such as interlock reset, external EDM, bypass and override, and fixed shielding and floating shielding through PC software, and qualified user operators can easily configure functions according to site usage.
 

External relay contact monitoring (EDM) function

The "External Relay Contact Status" is monitored to prevent the loss of safety protection functions due to external relay adhesion failures.
 

Interlock and reset function

The light curtains has optional interlock and reset functions, which can be easily implemented for manual reset and automatic reset.
 

Bypass and override functions

It is convenient to shield light grids for short periods of time under specific conditions without affecting machine operation.
 

Fixed and floating shielding

Fixed shielding facilitates special areas with shielding. Floating shielding is convenient for small and large workpieces and can also be used in scenarios where workpieces continue to pass.
