❓ FAQ – Questions & Answers

Q1: What is the main purpose of FS‑SDOL‑0424?
A1: It is used to provide four safe digital output channels with loop monitoring in safety systems, controlling field devices while detecting wiring faults.

Q2: What is the maximum current per channel?
A2: Each channel can drive up to 1.0 A at 24 V DC.

Q3: What type of outputs does it use?
A3: It uses solid-state source outputs that are protected against short circuits.

Q4: How does the loop monitoring work?
A4: It continuously checks each wiring path (lead) for open circuits or short circuits and raises a fault if a wire break or short is detected.

Q5: What happens under a fault or power loss?
A5: The module forces outputs into a safe (off) state to prevent unintended actuation.

Q6: What is the ambient operating temperature range?
A6: It is specified from –40 °C up to +85 °C.

Q7: What is the voltage drop when an output is loaded fully?
A7: The voltage drop is typically less than 1.3 V at 1 A.

Q8: What is its weight and size?
A8: Dimensions ~95 mm × 95 mm × 30 mm, weight ~0.18 kg.

Q9: Is it suitable for inductive loads?
A9: Yes, within its specifications—max inductive load 0.5 H and capacitive 1 µF.

Q10: What certifications does this module comply with?
A10: It’s designed to meet industrial safety standards (CE, UL, loop-monitoring safety specs).
