ABB rt6 115ac abb safety relay

Why Choose the ABB RT6 115AC 2TLA010026R0400 Safety Relay?

The ABB RT6 115AC 2TLA010026R0400 is a versatile universal machine safety relay designed for monitoring a wide range of safety devices in industrial machinery and automation systems. Part of the proven ABB Jokab Safety RT Series, the RT6 supports both single-channel and dual-channel safety circuits and can be used with emergency stops, interlocking switches, light curtains, light beams, safety mats, contact strips and other machine safeguarding devices.

This version operates from a 115 V AC, 50–60 Hz supply and provides 3 NO safety relay outputs plus 1 NC relay output. Two additional short-circuit-protected transistor information outputs provide status signals for the input conditions and output relay state, making it easier to integrate safety status information into machine control and diagnostic systems.

The RT6 incorporates monitored safety inputs, selectable reset arrangements and external-device monitoring capability for supervising downstream contactors and relays. With safety performance suitable for applications up to Category 4, PL e and SIL 3, fast response times and a compact 45 mm wide DIN rail housing, it provides a flexible solution for demanding machine-safety installations.

Universal Safety Monitoring for Industrial Machinery

The ABB RT6 is designed to supervise safety-related input circuits and control its redundant relay outputs according to the condition of the connected protective devices. Its flexible input arrangements allow the same relay platform to be applied to emergency-stop buttons, safety switches, light curtains, light beams, pressure-sensitive safety devices and other machine safeguards, simplifying safety control across different machinery designs.

The RT6 also provides reset and external-device monitoring functions that can be used to supervise downstream contactors and other switching devices. Its two transistor information outputs separately indicate fulfilled input conditions and activation of the output relays, providing useful diagnostic signals for associated machine control systems without relying on the safety contacts for status information.

Typical Applications

• Emergency-stop safety circuits.
• Safety gate, hatch and interlocking switch monitoring.
• Light curtain and light beam safety systems.
• Safety mats and pressure-sensitive contact strips.
• Hold-to-run and enabling devices.
• Foot-operated safety control devices.
• Machine area supervision.
• Safety output expansion applications.
• Industrial machinery and automated production equipment.
• Control panels requiring single-channel or dual-channel safety monitoring.
