Module de sortie AC Honeywell C200 TK-ODK161

Description

The TK-ODK161 is a high-density, isolated AC Output Module designed for integration into Honeywell process automation systems. This module features 16 individually isolated output channels engineered to switch alternating current loads across a wide voltage spectrum ranging from 74 to 265 VAC at line frequencies of 47 to 63 Hz. Each output is constructed with dedicated galvanic isolation barriers to prevent cross-channel interference and shield supervisory backplane electronics from field-side electrical transients. Designed for reliable signal delivery to final control elements such as solenoids, motor starters, and indicators, the module incorporates zero-crossing synchronization to suppress electromagnetic interference and thermal stress during load transitions.

Features

• 16 individually isolated output circuits providing channel-to-channel and user-to-system galvanic separation.
• Low on-state voltage drop and optimized power dissipation parameters for dense cabinet enclosures.
• High peak surge current capability to accommodate inductive and capacitive inrush loads.
• Integrated zero-crossing inhibition mechanisms to prolong field device operational life.
• Direct compatibility with high-density 36-position connection terminal blocks.

Applications

• Control of industrial solenoid valves and actuators.
• Interfacing with fixed-speed AC motor starters and contactors.
• Execution of pilot light arrays and visual signaling systems.
• Segregated load switching in chemical, petrochemical, and power generation environments.

Installation Guidelines

Grounding and Shielding

Ensure that the chassis rack and mounting backplane are securely bonded to the plant instrumentation grounding network. Field wiring shields, if deployed for noise mitigation, must be terminated at designated shield grounding bars outside the module assembly to prevent stray currents from entering the control logic plane.

Handling and ESD Protection

Electrostatic discharge can degrade or destroy internal solid-state components. Prior to inserting, removing, or wiring the module, personnel must wear a properly grounded static-dissipative wrist strap. Store and transport the unit exclusively in approved anti-static protective packaging.

Thermal Management and Airflow

Review thermal derating parameters when planning module layouts. Note that the total module current limits scale from 5.0 A at 30 Celsius down to 4.0 A at 60 Celsius. Maintain proper clearance margins between high-power equipment and the chassis to promote unhindered natural convection or forced-air circulation.

Wiring and Terminal Block Assignment

All field connections must be wired through the compatible TC-TBCH 36-position terminal block. Verify that the load requirements meet the minimum on-state threshold of 10 mA per output to guarantee proper switching operations and prevent leakage current false-activation states.

FAQ

What is the electrical isolation rating between channels for this module?

Every channel is fully isolated from adjacent circuits, withstanding testing procedures at 2546 VDC for a duration of 1 second.

What happens if the ambient operational temperature increases from 30 to 60 Celsius?

While individual points remain rated up to 2.0 A, the collective maximum module current capacity decreases from 5.0 A to 4.0 A.

Can this unit switch low-power instrumentation signals below 10 mA?

No, a minimum on-state current threshold of 10 mA per output channel is necessary for the solid-state switching circuitry to operate correctly.

What specific terminal block is required to interface with field wiring?

This module requires the TC-TBCH 36-position terminal block for managing field-side connections.

Does this device feature zero-crossing switching attributes?

Yes, it limits switching based on a maximum zero-crossing inhibit voltage threshold of 60 V peak to minimize inductive surges.

What is the typical output signal delay when operating on a standard 50 Hz line?

The propagation and signal processing delay for both turning on and turning off is approximately 11 ms at 50 Hz.

How much power does the module draw from the 24 VDC backplane supply?

The nominal continuous current consumption from the 24 VDC rail is extremely low, specified at 0.002 A.

What is the maximum transient surge current individual channels can tolerate?

Each output point can endure an inrush surge current of up to 20 A lasting for 43 ms, repeatable every 2 seconds at 60 Celsius.

What level of leakage current should be expected when an output is turned off?

The off-state leakage current can reach a maximum value of 3 mA per individual output point.

What is the net weight of the module excluding shipping materials?

The unboxed module weight is exactly 1 kg.
