Honeywell 8C-TAOXB1 51307137-175 Analog Output Module
Product Introduction
The Honeywell 8C-TAOXB1 (51307137-175) is a redundant analog output module designed for Series C I/O systems (e.g., Experion PKS C300). It delivers precise constant-current signals to actuators, recorders, and control valves, supporting both standard 4–20 mA and HART communication for advanced diagnostics and configuration. Its duplexed architecture ensures seamless switchover to a backup channel in case of a primary module fault, maximizing uptime in critical process environments.
Key Applications
Control of final elements such as control valves, dampers, and variable-frequency drives in oil & gas, petrochemical, and power generation plants.
Signal transmission to chart recorders, data historians, and operator interfaces in water/wastewater and chemical processing.
Integration with HART-enabled field instruments for parameter tuning, diagnostics, and secondary variable monitoring.
Redundant I/O installations in pharmaceutical and food & beverage plants requiring high reliability and audit-ready data.
Remote skid and offshore platform instrumentation where maintenance windows are limited.
Brand Overview
Honeywell has been a global leader in process automation since the 1980s, offering robust DCS platforms and Series C I/O modules. Renowned for reliability, long product lifecycles, and extensive support, Honeywell’s I/O hardware is widely deployed in mission-critical industries.
Product Advantages
-
High Reliability: Duplexed output channels with automatic failover prevent signal loss during module or channel faults.
-
HART-Enabled: Supports bi-directional HART communication on each channel for in-line diagnostics and remote configuration.
-
Precision & Stability: 16-bit resolution with ±0.1 % FS accuracy and <0.005 % FS/°C drift ensure tight control loops.
-
Robust Design: Coated PCB and industrial-grade components tolerate harsh environments (–20 °C to +60 °C, 5 – 95 % RH).
-
Easy Maintenance: Front-panel LEDs and dry-contact alarms provide immediate status; hot-swap capable for minimal downtime.

Frequently Asked Questions (FAQ)
Q: What redundancy features does the 8C-TAOXB1 support?
A: It provides dual redundant output channels with automatic failover and safe-state configuration per channel.
Q: Can the module communicate over HART?
A: Yes; each 4–20 mA channel supports bi-directional HART for parameter reading and diagnostics.
Q: How precise are the analog outputs?
A: Outputs are 16-bit with ±0.1 % FS accuracy and <0.005 % FS/°C drift.
Q: What environmental ratings does it meet?
A: Rated for –20 °C to +60 °C and 5 – 95 % non-condensing humidity.
Q: Is the PCB coated for harsh conditions?
A: Yes; conformal coating protects against moisture, dust, and corrosive atmospheres.
Q: How is module status indicated?
A: Front-panel LEDs show channel status, HART comms, and fault conditions; dry-contact alarms provide remote signaling.
Q: What power supply is required?
A: A single 24 V DC supply (±20 %) powers the module; typical consumption is 3.5 W.
Q: Can I hot-swap the module in the rack?
A: Yes; the Series C rack supports hot-swap replacement without shutting down adjacent modules.
Q: What isolation rating does each channel have?
A: Each channel is isolated to 1 500 VAC from other channels and the backplane.
Q: What rack or rail mounting options are available?
A: It fits standard Series C racks and can be mounted on DIN-rail adapters when space is limited.
