Frequently Asked Questions (FAQ)

Q1: What is the primary function of the 3500/32M 125720‑01?
A1: It provides four configurable relay outputs for machinery alarm and trip logic within the 3500 protection system.

Q2: Can each relay be independently configured?
A2: Yes. Each of the four channels supports independent logic configuration using AND/OR logic.

Q3: What is the relay contact rating?
A3: Each relay can carry 5 A at 24 V DC or 120 V AC, with arc suppression up to 250 Vrms.

Q4: Is this module suitable for harsh environments?
A4: Yes. It is epoxy-sealed, isolated, and rated for –30 °C to +65 °C operation under high humidity.

Q5: What diagnostic indicators are provided?
A5: LEDs indicate module health (OK), communication (TX/RX), and per-channel alarm status.

Q6: How much power does it consume?
A6: It typically consumes around 5.8 W during operation.

Q7: What are its dimensions and weight?
A7: Measures 241 × 24.4 × 99.1 mm and weighs approximately 0.4 kg.

Q8: Where is it installed within the rack system?
A8: Installed in full-height slots to the right of the transient data interface (TDI) module.

Q9: How long do the relay contacts last?
A9: They’re rated for approximately 100,000 operational cycles at rated load.

Q10: Can I add multiple modules for logic expansion?
A10: Absolutely—multiple 4‑channel modules can be added as needed for expanded logic.
