Vital Safety Controller, Base Unit 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. Cost-effective cable routing/connections Information output with two functions LED indication of: power supply, dynamic signal and outputs Detachable connector blocks Two NO safety outputs Manually supervised or automatic reset Can accommodate long cable lengths Standard width: 22.5 mm IP40 protection class rating A mechanical life of >107 operations Safety category 4, according to EN 954-1/EN ISO 13849-1 dynamic safety circuit Note Unused ports on the Tina 4A and 8A must be blanked by using a Tina 1A blanking plug.
