FAQ – Expert Selection Guide
- Q1: What is the maximum cable length for reliable output?
- A1: With module isolation, we recommend up to 500 meters. For over 300m, use shielded twisted-pair cables to reduce noise.
- Q2: Can this module drive both AC and DC loads?
- A2: No, SDV531-L33 is 24 V DC only. For AC loads, consider YOKOGAWA relay output modules.
- Q3: How do I verify output health without a multimeter?
- A3: Use the built-in diagnostic LEDs. A steady ON indicates normal output. Flashing means overload or short circuit.
- Q4: Is this module compatible with my existing ProSafe-RS rack?
- A4: Yes, it fits standard ProSafe-RS and CENTUM VP I/O slots. Verify firmware version for full diagnostic support.
- Q5: What spare parts should I keep for long-term operation?
- A5: We suggest keeping one spare module per 10 installed, plus a set of terminal blocks and fuses (1A slow-blow).
