Designed for integration within the 3500 Machinery Protection System, the 3500/50-04-CN delivers high-reliability tachometer measurements and speed monitoring capabilities. This module processes input signals from various speed sensors to provide rotational speed, acceleration, zero speed, and reverse rotation parameters, serving as a critical component in rotating machinery protection.
The 3500/50-04-CN configuration features an I/O module equipped with internal barriers and internal terminations (Option 04). This integration allows direct interfaces to transducers installed in hazardous environments without requiring auxiliary external barrier hardware. The country-specific agency approval (CN) ensures adherence to regional safety standards for industrial operations.

Prior to installing or servicing the 3500/50-04-CN module, ensure that local field wiring protocols for hazardous areas are fully met. The internal safety barriers rely on direct, low-impedance grounding paths to ensure intrinsic safety protection. Maintain routing separation between intrinsically safe transducer wiring and non-intrinsically safe cabling within the enclosure.
