Honeywell/51304335-225MU/MC- TAOX52|Analog Output Module

The 51304335-225 (MU/MC-TAOX52) is a high-precision Field Termination Assembly (FTA) designed for the Honeywell TDC 3000 and Experion PKS control systems. This module serves as a robust interface between the system's control processors and field-mounted actuators, translating digital commands into accurate 4-20 mA analog signals.

Engineered for reliability in volatile industrial settings, the 51304335-225 is certified for use in Division 2 hazardous locations. Its non-incendive output circuitry ensures that electrical energy levels remain below the point of ignition, allowing for safe operation without the need for traditional explosion-proof enclosures or intrinsic safety barriers in specific zones.
