Q1: What is the role of FC‑IO‑0002 in the system?
A1: It extends control functions—communication, power, watchdog—to I/O modules.
Q2: How is redundancy achieved?
A2: Installed in primary and standby slots; standby module takes over if primary fails.
Q3: What voltage does it distribute?
A3: Supplies 5 V to two distinct groups of I/O positions, each capable of >1.25 A.
Q4: What does the status LED indicate?
A4: Off means no power, green means healthy operation, red indicates fault.
Q5: Can it isolate faulty modules?
A5: Yes, through watchdog signal control it can disable failing I/O slots.
Q6: What are the module’s power input specs?
A6: Dual 5 V DC inputs via OR-ing circuits, supporting up to about 100 mA.
Q7: What are its physical dimensions?
A7: Occupies 4 TE (HP) width and 3 HE height in a rack enclosure.
Q8: How much does one weigh?
A8: Approximately 300 g.
Q9: What temperature range can it operate in?
A9: Typically –40 °C to +70 °C.
Q10: Is it safety-certified?
A10: Yes, holds CE, TÜV, UL, and CSA approvals.
