ABB rt9 24dc abb safety relay
ABB RT9 2TLA010029R0000 is a compact 24 V DC universal machine safety relay with five selectable input configurations, 2 NO safety outputs and manual supervised or automatic reset for industrial safeguarding applications.
Why Choose the ABB RT9 24DC 2TLA010029R0000 Safety Relay?
The ABB RT9 24DC 2TLA010029R0000 is a compact and 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 RT9 provides multiple selectable input configurations for emergency stops, interlocking switches, light curtains, light beams, safety mats, contact strips and other machinery safeguarding devices.
Operating from a 24 V DC supply, the RT9 provides 2 NO safety relay outputs together with a changeover information output for signalling relay status to a PLC, indicator or other control equipment. Five selectable input configurations support single-channel, dual-channel and pressure-sensitive safety-device applications, allowing one compact relay to address a broad range of machine-safety requirements.
The RT9 incorporates internal dual and supervised safety functions, selectable manual supervised or automatic reset and rapid input-to-output response. Depending on the selected input arrangement and overall safety-system design, the relay can support applications up to Category 4 and Performance Level e (PL e). Its slim 22.5 mm wide DIN rail housing also helps minimise control-panel space requirements.

Flexible Safety Monitoring for Industrial Machinery
The ABB RT9 can be configured for five different safety input arrangements, including a single-channel NO input, dual-channel NO inputs, dual-channel NO/NC inputs, dual-channel inputs referenced to different supply potentials and safety mat or contact-strip monitoring. This flexibility allows the same relay to be adapted to different protective devices while achieving the safety performance appropriate to the selected configuration.
For applications requiring deliberate restart, the RT9 provides a manual supervised reset that monitors the reset operation before enabling the safety outputs. Automatic reset can also be selected where permitted by the machinery risk assessment. Internal supervision, fast response and status indication make the RT9 a practical safety interface for both straightforward and more demanding industrial machinery circuits.
Typical Applications
- Emergency-stop safety circuits.
- Safety gate, hatch and interlocking switch monitoring.
- Light curtain and safety light-beam 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 production machinery and automated equipment.
- Control panels requiring compact universal safety monitoring.
