Description

The Honeywell CC-TDOB11 (Part Number: 51308373-175) is a 16-channel digital output module designed for use in Honeywell Experion® PKS, TPS (Total Plant Solution), and legacy Plant Web distributed control systems (DCS). It provides isolated, high-voltage switching capability using electromechanical relays to directly control field devices such as motor starters, solenoid valves, alarm panels, and indicator lights.

Engineered for industrial reliability, the CC-TDOB11 features front-panel LED status indicators, conformal-coated circuitry, and robust relay contacts rated for both AC and DC loads—making it ideal for demanding applications in oil & gas, power generation, water treatment, and manufacturing.

Application Scenarios

At a Midwest municipal wastewater treatment plant, operators struggled with frequent failures in auxiliary blower control due to outdated solid-state output cards that overheated under continuous cycling. After upgrading to Honeywell CC-TDOB11 51308373-175 modules, the plant achieved stable operation for over 18 months. The electromechanical relays handled the inductive load of contactor coils without degradation, while the green/red LEDs enabled instant visual verification during maintenance rounds. “We went from weekly troubleshooting to zero output-related work orders,” noted the lead controls technician—highlighting how the CC-TDOB11 delivers simplicity, durability, and long-term cost savings in real-world operations.

Technical Principles and Innovative Values

Innovation Point 1: True Electromechanical Relays for Universal Load Compatibility

Unlike solid-state outputs limited to resistive or low-inductance loads, the CC-TDOB11 uses gold-alloy electromechanical relays capable of switching both AC and DC—including motor contactors and solenoid valves—without external interposing relays.

Innovation Point 2: Direct Integration with Honeywell RIO Architecture

The CC-TDOB11 plugs directly into Honeywell Remote I/O (RIO) stations connected via redundant FTE (Fault Tolerant Ethernet) or legacy LCN networks. No configuration jumpers or software binding are needed—ensuring rapid deployment and replacement.

Innovation Point 3: Visual Diagnostics for Rapid Troubleshooting

Each of the 16 channels features a bright green LED that illuminates when the output is energized. This allows technicians to verify command execution at a glance—critical during emergency response or night shifts.

Innovation Point 4: Legacy System Longevity Through Proven Reliability

While newer systems use Ethernet-based I/O, thousands of plants still rely on TPS and early Experion PKS. The CC-TDOB11 ensures these installations remain operational with factory-fresh, tested replacements—delaying costly full-system migrations.

Application Cases and Industry Value

In a Canadian pulp & paper mill running a 1990s-era TPS system, the CC-TDOB11 was used to control steam header isolation valves. During a winter freeze event, older output cards failed due to condensation-induced leakage. After replacing them with conformal-coated CC-TDOB11 51308373-175 units, the plant maintained valve operability even at -30°C ambient. The relays’ mechanical action also prevented “sticking” common in SSRs under low-load conditions.

Similarly, a U.S. ethanol plant integrated CC-TDOB11 modules into its grain dryer control panel. The ability to switch 240 VAC heater circuits directly—without intermediate contactors—reduced panel footprint by 30% and improved mean time between failures (MTBF) by over 4×.

Installation, Maintenance, and Full-Cycle Support

Installation of the CC-TDOB11 involves inserting it into a compatible Honeywell RIO or FTEB chassis until it clicks into place. Field wiring connects via screw terminals on an optional terminal base (e.g., CC-TB11), supporting 14–22 AWG wire. The module is automatically recognized by the controller—no DIP switches or software downloads required.

Maintenance is minimal: periodically inspect LEDs for expected state, ensure terminal screws are tight, and verify no signs of arcing on relay contacts (typically unnecessary unless switching highly inductive loads frequently). The CC-TDOB11 contains no batteries, fans, or consumables, ensuring decades of service in stable environments.

Every CC-TDOB11 51308373-175 we supply undergoes full functional testing, including contact resistance (<50 mΩ), isolation integrity, and LED verification. Units are burned-in at elevated temperature to screen for early-life failures.

We provide terminal diagrams, compatibility matrices, and cross-reference support for obsolete variants (e.g., 51308373-100 vs. -175). All modules include a test certificate and 12-month warranty.
