DIN-rail Controller and Light Curtain


Big on Safety - Small in Size
Diverse Redundancy Design Concept
The DIN-Rail safety light curtain utilizes the diverse redundancy design concept. This gives the safety light system a higher level of redundancy and control reliability. The two microprocessors are of different design, and the microprocessor or parallel programs are run and made up from different instruction sets written by different programmers.

Self-Checking Circuitry
The DIN-Rail safety light curtain self-checks every 20 milliseconds. Self-checking is the ability to electronically verify that all of the systems' critical internal circuit components and their redundant counterparts or back-ups are operating properly.

Extra Safe Design

Provides tow methods of cross monitoring design. One utilizes two microprocessors and two captive contact relays and the other uses four watchdog timers monitoring the system and the captive contact relays.

External Diagnostic Message Display
Standard on all DIN-Rail safety light curtains is the "External Diagnostic Message Display"

Extensive Testing
The DIN-Rail safety light curtain incorporates extensive testing and burn-in to establish a high degree of product reliability and safety.

Redundant Captive Contact Safety Relays
Redundant relays assure safety if an output relay should fail. The DIN-Rail utilizes safety relays which have force-guided contacts. This is a configuration where the contacts are mechanically locked together so that if one set of contacts weld, the other contacts cannot change state. If one should fail, code "Relay Fault" will be displayed on the diagnostic message display. The complete guarding system consists of two miniature pylons with a controller for system diagnostics and wiring interface.

Alphanumeric Plain English Messages
Scrolling message display shows status and fault codes of the unit. This is an excellent safety and maintenance feature which is unparalleled in the machine guarding industry for enhancing machine utilization.

Control Reliable System
Critical components of the DIN-Rail are duplicated so that a single component failure will not cause an unsafe condition. If a component does fail, the units' self-checking circuitry recognizes the situation and initiates a safe stop of the machine. The fault is then displayed on the message display.

Powerful Infrared Light Source
The DIN-Rail safety light curtain utilizes powerful, safe, and predictable infrared light as its sensing source. This gives the system greater reliability and enhances machine utilization by minimizing nuisance trips and shutdowns caused by dirt, coolants, lubrication mists and machine oils. The DIN-Rail is highly immune to EMI, RFI, and ambient light conditions and are unaffected by strobe lights and weld flash generated light sources.


Standard System Features for
DIN-rail Controllers
