Honeywell FC-TSAOH-0220M Safety Manager Safe Analog Output Field Termination Assembly

Description

The Honeywell FC-TSAOH-0220M is a conformal-coated, two-channel Safe Analog Output Field Termination Assembly (FTA) engineered for the Honeywell Safety Manager and Fail-Safe Control (FSC) process safety architectures. Serving as the field-wiring interface for the SAO-0220m analog output module, the assembly distributes 0 to 20 mA and 4 to 20 mA current loops to critical field actuators while enabling point-to-point HART frequency-shift keying (FSK) digital communication across both channels.

The FC-TSAOH-0220M links to the active or redundant SAO-0220m safety module pair using a pre-assembled system interconnection cable (SICC-0001/Lx). By decoupling high-density system rack electronics from cabinet field wiring, the terminal assembly ensures clean signal distribution, provides dedicated test and loop disconnect points, and incorporates pass-through connectors for external HART multiplexing networks.

The module features a factory conformal coating (CC designation) that protects sensitive circuit traces from moisture, chemical contaminants, and airborne pollutants typically found in process cabinets. Compact packaging allows high-density DIN rail mounting in local or remote Safety Manager input/output cabinets.

Features

• Two independent safe analog output channels operating at 0 to 20 mA or 4 to 20 mA with a common 0V return reference.
• Integrated bidirectional HART communication interface across both output channels for field device parameter configuration and continuous device health diagnostics.
• Standard system interface supporting direct connection to non-redundant or redundant Honeywell SAO-0220m output cards via SICC-0001/Lx cabling.
• Heavy-duty screw terminal blocks accommodating field conductor gauges up to 2.5 mm2 (AWG 14).
• Universal mounting foot designed for direct snap-on installation to symmetrical TS35 and asymmetrical TS32 DIN EN rails.
• Conformal coating (CC V1.0) applied to electronic assemblies to withstand harsh industrial environmental classifications.

Applications

• Safety Instrumented System (SIS) final control element modulation in oil, gas, petrochemical, and refining facilities.
• Emergency shutdown (ESD) valve positioning loops requiring SIL-rated analog actuation with concurrent HART digital valve position feedback.
• Turbomachinery, compressor, and pump speed control loops driven through variable frequency drive analog setpoints.
• Burner Management Systems (BMS) modulating fuel-to-air ratio valves in utility and industrial boilers.
