Product Overview

The TC-FOD161 is a Honeywell 24 Vdc source digital output module designed for protected industrial control applications. This module delivers reliable on/off control with 16 non-isolated channels in a single group, making it ideal for driving solenoids, relays, and indicator lamps in demanding environments. Its DIN-rail mounting simplifies installation in control panels.

Technical Specifications Analysis

The TC-FOD161 operates on an external dc power supply voltage range of 19.2-31.2V dc with 5% ac ripple. It provides an ON-state voltage from 10V dc minimum to 31.2V dc maximum, with a nominal 24V dc. Each channel supports an ON-state current from 1mA minimum to 500mA maximum, and a surge current of 1.5A for 50ms repeatable every 2s. The OFF-state voltage drop is 0.5V dc maximum, and OFF-state leakage is 0.5mA maximum. Maximum input delay times are 0.5ms OFF to ON and 1.0ms ON to OFF. The module dissipates 5W power and 17 BTU/hr thermal dissipation at 31.2V dc. It includes 16 yellow channel status indicators and measures 69mm x 94mm x 80mm.

Application Scenarios & Usage Methods

In oil and gas facilities, the TC-FOD161 controls valve actuators and alarm systems. For example, connect the module's 24V dc source outputs to solenoid valves in a pipeline skid. The 500mA per channel capacity easily drives most industrial solenoids. In petrochemical plants, use it to switch indicator lights on a control panel, leveraging the 16-channel density to reduce wiring complexity. The 1.5A surge current capability handles inrush loads from incandescent lamps or contactor coils.

Installation Guide & Packing List

Mount the TC-FOD161 on a standard DIN rail inside an enclosure. Use 12 gauge stranded wire with 3/64 inch maximum insulation and 90C minimum temperature rating. Tighten terminal screws to 4-7 inch-pounds. Ensure the module receives 19.2-31.2V dc external power with less than 5% ac ripple. The package includes the TC-FOD161 module and a product documentation sheet.

Purchasing Advice

When selecting a digital output module, verify that your load current per channel does not exceed 500mA and your supply voltage stays within 19.2-31.2V dc. The TC-FOD161 is certified for Class I Division 2 and Zone 2 hazardous locations, making it suitable for oil and gas environments.

Repair & Maintenance Tips

Periodically inspect the TC-FOD161 for loose connections or debris on the DIN rail. Clean the module with a dry cloth; do not use solvents. Store the module in a clean, dry environment between -40 to 85 C. Check the 16 yellow status indicators during operation to confirm channel activity. Replace the module if any channel fails to switch or shows continuous overcurrent.
