Product Overview

The 3500/53-02-00 is a two-channel electronic overspeed detection system for turbines and compressors. It accepts proximity probe or magnetic pickup signals. Modules combine for 2-out-of-2 or 2-out-of-3 (recommended) voting, ensuring fail-safe operation in the 3500 rack.

Technical Configuration

Channel Option: 02 – Two Channel System

The 02 suffix designates a two-channel module. Each channel accepts one transducer input. Multiple modules combine for voting architectures.

Agency Approval: 00 – None

Standard version without hazardous area certifications. Complies with FCC, EMC, LV, and RoHS. For Class I, Div 2, order CSA/NRTL/C option (01).

Installation & Maintenance

Wiring

Connect probes or pickups to I/O inputs. Use shielded twisted-pair cables. Front panel provides buffered output (coaxial, 550Ω) for diagnostics – short-circuit and ESD protected.

Configuration

Set overspeed setpoints and voting logic via 3500 Configuration Software. Use three modules for 2-out-of-3 voting. Relays selectable for Normally Energized or De-energized.

Hazardous Area

For Class I, Div 2 (Groups A-D), order CSA/NRTL/C option (01) – T4 at Ta = -20°C to +65°C. Standard (00) for general industrial use.

Engineering Advantages

Redundant Voting Architecture

2-out-of-3 voting provides exceptional reliability. System trips only when two modules detect overspeed – remains functional with one module failure.

Robust Relays

Epoxy-sealed SPDT relays with arc suppressers. 100,000 operations at 5A, 24Vdc or 120Vac ensures long-term durability.

Wide Compatibility

Operates -30°C to +65°C, 95% humidity. -24Vdc supply and 20kΩ input support both proximity probes and magnetic pickups.

Technical FAQs

Q1: Recommended voting configuration?

A1: 2-out-of-3 using three 3500/53 modules. System trips only when at least two detect overspeed.

Q2: Is recorder output short-circuit protected?

A2: Yes. +4 to +20 mA output is protected. Operation unaffected by shorts. Load: 0 to 600Ω.

Q3: Difference between 02 and other channel options?

A3: 02 = two-channel module. Multiple modules required for voting – channel option does not affect voting capability.
