ABB 2TLA020070R8500 Safety Output Module Pluto O2

ABB Pluto O2 Safety Output Module, part number 2TLA020070R8500, is a 24 VDC safety I/O module designed for the Pluto safety bus on ABB safety PLC systems. This 45 mm wide DIN‑rail device provides six I/O channels for safety control: two fail‑safe inputs (I0, I1), two configurable channels (IQ10, IQ11) that can operate as either fail‑safe inputs or non‑safety outputs, and two fail‑safe relay outputs (Q0, Q1) with three contacts each. The unit is grey and intended for installation on a standard DIN rail, with a supply/operating voltage of 24 VDC ±15% and a current consumption of about 100 mA; ABB recommends a 6 A external fuse and lists six indicator LEDs for quick status checks. Dimensions are 45 x 84 x 118 mm, and the enclosure protection is specified as IP40 (with IP20 at the terminal level in some configurations). Operating temperature ranges from -10 to +50 °C with storage from -25 to +55 °C. The Pluto O2 module is designed to act as a compact safety output stage within ABB’s Pluto safety ecosystem, delivering rapid input-to-output responses suitable for safety‑critical actuation on the Pluto bus.
