Safety relay for guarding circuits
The ABB 2TLA010028R2400 is an RT7A safety relay with a 115 VAC coil, designed for use in safety circuits that monitor emergency stops, light curtains, or interlock switches on industrial machinery.
No lifecycle events like discontinuation or last-time-buy have been announced for this order code.
Deployment context
As a safety relay, the 2TLA010028R2400 is typically mounted inside a control panel on DIN rail, wired between safety input devices (E-stops, guard switches) and the contactors or drives that must be de-energized in a fault condition. The 115 VAC coil voltage means it is suited for panels with a 120 VAC control transformer, common in North American and some European installations.
