Installation Guide

1. Install the BMXSDO0802 into a standard X80 backplane slot (M580 Safety or Quantum rack).
2. Secure the module with the captive screw.
3. Install the 20-way removable terminal block (BMXFTB2010/2000/2020) into the front connector.
4. Connect 24 VDC PELV process power supply to pins 18 and 20.
5. Connect field actuators (solenoids, contactors, motor starters) to output pins 2, 4, 6, 8, 10, 12, 14, 16.
6. Connect common 0V to pins 1, 3, 5, 7, 9, 11, 13, 15, 17, 19.
7. Install a fast-blow external fuse (max 6 A) in the process power supply line.

FAQ

Q: What safety integrity level does BMXSDO0802 achieve?
A: SIL3, Category 4, Performance Level e (PLe) per IEC 61508 and ISO 13849-1.

Q: Can I use SELV or PELV power supply?
A: Both are acceptable. Both SELV and PELV are Extra-Low-Voltage systems (≤ 50 VAC). SELV has higher requirements than PELV and can be used instead of PELV.

Q: What is the difference between BMXSDO0802 and BMXDDO1602?
A: BMXSDO0802 is a safety output module (8 channels, SIL3/Cat4/PLe). BMXDDO1602 is a standard discrete output module (16 channels, non-safety).

Q: Does BMXSDO0802 require an external fuse?
A: Yes. A fast-blow fuse (max 6 A) is required to protect the external power supply against short-circuit and overvoltage conditions.

Q: What happens when a safety fault is detected?
A: The module sets its outputs to the safe state (de-energized) and maintains this state until the fault is cleared and the module is restarted. Fallback state (energized, de-energized, or hold last value) is configurable via Control Expert Safety.

Q: Is BMXSDO0802 compatible with M340?
A: No. BMXSDO0802 is designed for M580 Safety and Quantum systems. M340 does not support safety I/O modules.

Selection Tips

• M580 Safety, 8-channel safety output, SIL3/Cat4/PLe: BMXSDO0802
• M580 Safety, 16-channel safety input: BMXSDI1602
• M580 Safety, 4-channel safety relay output: BMXSRA0405
• Standard X80, 16-channel discrete output: BMXDDO1602
• Always verify: Safety integrity level requirement, process power supply type (PELV/SELV), and external fuse rating
• Order compatible terminal block: BMXFTB2010 (screw), BMXFTB2000 (cage), or BMXFTB2020 (spring)
