ABB Light Beam/Curtain, Safety Switch/Interlock Safety Relay, 24V dc, 2 Safety Contacts

The Vital safety device from ABB is the heart of a new solution which makes it possible to install/connect many different types of safety device in the same safety circuit and still achieve safety category 4 in accordance with EN 954-1/EN ISO 13849-1. The Vital module is based upon a dynamic single-channel concept as opposed to conventional dual-channel safety relays. ABB have designed this unit to accommodate up to 30 dynamic sensors within the safety circuit which can be supervised by one Vital module. The Vital unit can therefore replace several safety relays. Safety components with output contacts can be connected to the Vital via low cost Tina adaptors. The Vital also has automatically or manually supervised reset selection, dual safety outputs, and an information output for reset indication and status information for PLC's.

Accurately monitor potential errors in machinery or plants with this safety relay from ABB. The module generates signals to maintain a Category 4 safety level, preventing injuries and reducing risks. You can install or connect up to 30 dynamic sensors within a safety circuit through this innovative unit. The use of a single safety signal helps with the quick and simple installation of an entire system. A light curtain provides added protection by disconnecting equipment when triggered.

• LED indicator shows the power and relay status outputs of programmable logic controllers (PLCs)
• IP40 (ingress protection) rating indicates the internal components are shielded from tools and wires over 1mm to prevent damage
• Detachable connector blocks for easy module assembly and maintenance
• Can accommodate long cable lengths for easy reach without moving equipment

• Movable guards for enclosures
• Magnetic switches
• Non-contact safety switches
• Emergency stop buttons

A safety relay is normally used for a combination of switches and is specifically installed to detect faults in an electrical circuit. Standard relays link contacts for the transfer of power signals.
