Honeywell FC-TSAO-0220M Safe Analog Output FTA Module

The Honeywell FC-TSAO-0220M, also cataloged as the FC-TSAO-0220M Safe Analog Output Module, operates as a dedicated hardware component for safe analog current signal transmission within Honeywell Safety Manager platforms.

Hardware Specifications

4-20 mA HART Loop Protocol & Channel-to-Channel Isolation

The unit utilizes galvanic isolation between channels and internal system buses to execute field analog control commands. Compatible with standard 4-20 mA HART loop protocol instruments, the module delivers analog output driving current with +/-0.5% full-scale precision. Channel-to-channel isolation prevents electrical ground loops and high-voltage line transients from propagating between individual control loops, maintaining signal accuracy across hazardous location installations.

Frequently Asked Questions

Q: How many analog output loops can be driven by a single FC-TSAO-0220M module?

A: The FC-TSAO-0220M provides 2 isolated output channels supporting 0-20 mA or 4-20 mA loop current configurations.

Q: What hazardous area protection classification applies to the FC-TSAO-0220M?

A: The module is rated Ex ia IIIC T6 for intrinsically safe operation in industrial environments.

Field Installation Guidelines

• Isolate loop power supplies before connecting or disconnecting field wiring terminals on the module chassis.
• Route current loop conductors in shielded, twisted-pair cables separated from high-voltage AC lines to mitigate electromagnetic noise.
• Connect signal cable shields to the main earth ground bar at a single point to prevent ground loop currents across isolated channels.
• Verify ambient panel temperature remains within the specified range of -20 to +70 deg C to maintain accurate current loop regulation.
