Selection & installation notes
- Respect both limits simultaneously: 3 A per output and 10 A total at the common terminal. Derate from 40°C upward and provide ventilation.
- Use semiconductor fast-fuse protection and suitable surge suppression; allow current margin for inductive or capacitive loads. Isolate the main supply before servicing.
- The source mixes a barrier-terminal specification (M3, 8 mm pitch, ≤1.25 mm², 1.2 N·m) with cage/spring/pluggable model tables. Do not apply that torque or wire size to these variants without confirmation.
- The 16-channel selection row specifies COM− output, while the general description offers either polarity. Confirm the exact output version.
- The source outline table gives the dimensions above, while separate annotations give approximately 39/87 mm. Obtain the exact terminal-variant drawing before layout.
- Ordering codes are not freely interchangeable. Confirm the full part number, input range, output polarity and terminal style.
