Every guarded machine needs at least one clearly reachable emergency stop. ABB's Smile range is a family of compact, easy-to-install emergency-stop stations built around a small yellow enclosure and a red mushroom button. The Smile 12 EA Tina (order number 2TLA030050R0200) goes further: it is a complete emergency-stop button with an integrated Tina DYNlink adaptation unit and a status LED, ready to drop straight into a dynamic safety loop. This guide covers its verified specifications, how it performs the stop function, how it connects, and how it differs from the separate Tina adapter blocks.
What Is the Smile 12 EA Tina?
The Smile 12 EA Tina is an emergency-stop button in a compact Smile enclosure. The "12" identifies the dual-connector version, "EA" denotes the emergency-stop actuation with turn-release reset, and "Tina" means a DYNlink adaptation unit is built in rather than added externally. Pressing the red mushroom head opens the safety contacts; it is reset by turning the head. A status LED inside the button shows the circuit state at a glance, simplifying fault finding on the guard.

The Emergency-Stop Function
Pressing the red mushroom head mechanically opens the two normally closed safety contacts, which removes the signal that keeps the machine's safety outputs energized. Because the contacts are positively opened according to the international emergency-stop convention, the machine stops reliably regardless of where the button is pressed. Reset is not automatic: the operator must twist the head to release it, preventing an unintended restart. This deliberate reset is a core part of any safe stop design and is required before the safety controller can re-enable the outputs.
How It Connects to a DYNlink Loop
Unlike a conventional E-stop that runs two hardwired contacts back to a safety relay, the Smile 12 EA Tina carries its own Tina adaptation electronics inside the enclosure. A 24 V DC supply and the DYNlink communication are handled over the M12 connectors. With one M12-5 male connector on one end and one M12-5 female connector on the other, multiple Smile stations can be daisy-chained along a guard: cable in from the controller, pass-through to the next station, and out to the end of the run. The status LED on each button shows whether that device is healthy, so a technician can walk the loop and identify the pressed or failed unit without a meter.
ABB publishes that, with the Tina/DYNlink approach, long strings of safety devices can be run back to a single controller input — up to roughly 30 devices in series to a Vital safety controller, or up to about 10 devices in series to one Pluto safety PLC input — while still reaching Category 4 / Performance Level e / SIL3 with the appropriate controller and loop configuration. The exact device count and category must be confirmed during the machine's safety validation.
How It Differs From the Tina 12A Adapter
It is easy to confuse the two because both carry the "Tina" name, but they are different products in different roles:
| Smile 12 EA Tina (2TLA030050R0200) | Tina 12A (2TLA020054R1800) | |
|---|---|---|
| What it is | A complete emergency-stop button station | A passive connection/junction block |
| Provides a stop function | Yes, with 2 safety contacts | No |
| Connectors | M12-5, one male and one female | M12-8, two female and one male |
| Connects | Sits in the loop as the E-stop device itself | Branches two existing M12-8 DYNlink devices |
| IP rating | IP65 | IP67 |
In short, the Smile 12 EA Tina is the safety device, while the Tina 12A is a wiring accessory that joins two other devices. Our ABB range lists both families for comparison.
Mounting and Applications
The compact enclosure and centered mounting holes make the Smile 12 EA Tina especially quick to fix onto aluminum extrusions such as machine guarding and fence systems, and its small footprint lets it fit into reduced spaces. Typical uses include:
- Guarded manual workstations and robotic cells
- Conveyors, packaging machines, and press tending stations
- Aluminum-extrusion guards and fence systems with multiple E-stops chained in one loop
- Retrofits where replacing a hardwired E-stop with a DYNlink station reduces panel wiring
Lifecycle and Spare Parts
Emergency-stop stations are wear items on high-use machines because the mushroom head is pressed and reset frequently, and the LED and contacts are exposed to daily handling. When replacing a Smile 12 EA Tina, match order number 2TLA030050R0200 to preserve the M12-5 DYNlink pinout, turn-release action, and status-LED behavior. Older or unavailable safety stations can often be sourced through our Discontinued Products range; send the part number and we will confirm availability and compatible alternatives.
Frequently Asked Questions
Does the Smile 12 EA Tina need a separate Tina adapter?
No. A Tina DYNlink adaptation unit is built into the enclosure, so the button connects directly to a DYNlink loop over its M12-5 connectors without an external adapter.
How is the button reset after an emergency stop?
The mushroom head is reset by turning it (turn-release). It does not reset automatically, which is required to prevent an unexpected restart.
What safety level can it reach?
With a suitable ABB Vital or Pluto safety controller and a correctly configured loop, the system can reach up to Performance Level e / Category 4 / SIL3. The final level depends on the full circuit, not the button alone.
How is it mounted on machine guards?
It is surface-mounted using the centered mounting holes, which align with standard aluminum extrusion guard profiles, and carries an IP65 enclosure rating for shop-floor use.
