Overview
The ABB 2TLA010030R5000 is a safety-rated expansion relay from the E1T series, engineered to expand the output capacity of ABB safety control relays. This unit provides a 3-second off-delay function and four normally open (4NO) relay outputs with dual-channel redundancy for safe operation. Rated for 24VDC supply voltage, the relay is designed to meet safety category 4 standards and is suitable for industrial automation applications requiring monitored or delayed shutdown sequences.
