Overview
The ABB 2TLA010030R0000 is a safety expansion relay in the E1T series, engineered to expand the output capacity of safety relay systems. This compact module operates on 24VDC and delivers 4 normally open (4NO) enabling path outputs with a 0-second time delay, making it ideal for industrial machinery control and emergency stop circuits. The relay meets EN62061 and ISO13849-1 safety standards, ensuring compliance with Category 4 safety requirements.
Key Features
- Four 4-output enabling paths with dual series NO contacts per path; rated 2A (240VAC, AC-15) / 1A (24VDC, DC-13)
- Single test output (X1–X2) with dual series NC contacts for monitored circuit verification
- Twin stop function with mechanically operated contacts for reliable fault detection
- LED indicators for visual output status confirmation
- Quick-release connector blocks for fast field installation and removal
- DIN rail mounting; compact 22.5 mm width for tight panel layouts
- Ag+Au flash contact material for long operating life and low contact resistance
