Product Overview
The Honeywell CP-DYNA-2AIO is a 16-channel analog input/output backplane in the CP-DYN interface assembly family. It is used to connect compatible MTL4500-series intrinsic safety interfaces with a distributed control system or other industrial control equipment.
Unlike the larger Size B backplane configurations, the CP-DYNA-2AIO uses a Size A arrangement. Its 16-channel analog interface supports both input and output signal connections, making it suitable for process installations that require analog measurement acquisition and control signal distribution.
The backplane is associated with the MTL4544 and MTL4549Y interface modules. These modules form part of the signal conditioning arrangement between field instrumentation and the control system. Typical field devices include pressure transmitters, temperature transmitters, flow instruments, and other analog process instruments.
The CP-DYNA-2AIO belongs to a cable-connected Field Termination Assembly (FTA) arrangement. It uses a Tyco Dynamic 20-pin connector system to establish connections between the FTA and the control system interface card. This arrangement allows the field interface assembly to be installed remotely from the main control system.
For replacement and system expansion projects, the correct Size A configuration and compatible MTL interface modules must be verified. The CP-DYNA-2AIO should not be treated as a direct substitute for the larger CP-DYNB-AIO because their module arrangements and supported interface types differ.

Product Working Principle
The CP-DYNA-2AIO operates as a field termination and connection platform within an analog signal interface system.
For analog input applications, field transmitters generate electrical signals representing process variables such as pressure, temperature, flow, and liquid level. These signals are connected to the corresponding MTL interface modules installed in the FTA arrangement.
The MTL4544 and MTL4549Y modules provide the designated interface between field circuits and the control system. The CP-DYNA-2AIO provides the physical and electrical connection arrangement for these modules and the associated system wiring.
For analog output applications, control signals from the automation system pass through the corresponding interface modules toward compatible field equipment.
A simplified signal arrangement is:
Field Instruments → MTL4544 / MTL4549Y Interface Modules → CP-DYNA-2AIO → Tyco Dynamic Cable → Control System Interface Card
The backplane itself does not execute PLC logic or independently perform analog signal conversion. Its primary function is to organize and connect the installed interface modules and their associated electrical connections.
The cable-connected arrangement also allows the field termination assembly to be positioned separately from the control system. This is useful in installations where field wiring and control equipment are located in different cabinet sections or equipment areas.
Correct module selection and connector pin assignments are essential for maintaining the intended input and output signal paths.
Role in Honeywell / MTL Control Architecture
Within the CP-DYN architecture, the CP-DYNA-2AIO serves as the Size A analog field termination assembly. It connects compatible MTL4500 interface modules with the control system through a dedicated multiway cable connection.
Its 16-channel analog configuration allows multiple process signals to be grouped within one interface assembly rather than requiring separate individual connections for every field signal.
A typical connection arrangement is:
Field Instrumentation → MTL4500 Interface Modules → CP-DYNA-2AIO → CABDYN20 Cable → DCS / PLC System Card

Installation and Maintenance
- Verify Backplane Compatibility: Confirm that the CP-DYNA-2AIO is the required Size A configuration for the existing CP-DYN system.
- Inspect the Assembly: Check the backplane, connector contacts, mounting points, and interface connections for visible damage.
- Confirm Module Selection: Verify that the installed MTL interface modules are compatible with the CP-DYNA-2AIO, particularly MTL4544 and MTL4549Y.
- Isolate the Equipment: Follow the site’s electrical isolation procedures before removing or installing the FTA assembly.
- Prepare the Mounting Position: Select a suitable cabinet or panel position that allows access to the interface modules and cable connections.
- Check Mounting Hardware: Verify that the designated mounting pillars or DIN rail mounting arrangement are correctly prepared.
- Install the Backplane: Secure the assembly using the appropriate mounting hardware and avoid applying excessive mechanical force.
- Install Interface Modules: Position the compatible MTL modules according to the designated channel arrangement and installation instructions.
- Connect the Dynamic Cable: Verify the Tyco Dynamic connector orientation and connect the cable to the designated system interface card.
- Verify Channel Wiring: Check the analog input and output signal assignments against the control system wiring diagrams.
- Perform Functional Testing: Test the connected analog channels and confirm that measurement and control signals are correctly transferred.
- Complete Routine Inspection: Inspect connector contacts, cable condition, mounting security, and signal performance during scheduled maintenance.
If multiple analog channels become unavailable simultaneously, inspect the common connector and cable connections before replacing individual interface modules. Also verify that the installed modules match the intended CP-DYN configuration.

Technical FAQs
1. How many analog channels does the CP-DYNA-2AIO support?
The CP-DYNA-2AIO is specified as a 16-channel analog input/output FTA. Its channel arrangement supports analog input and output connections using compatible MTL interface modules.
2. Which MTL modules are compatible with the CP-DYNA-2AIO?
The MTL4500 documentation identifies MTL4544 and MTL4549Y as the compatible interface modules for this backplane. Other MTL4500 modules should not be assumed compatible without checking their designated FTA configuration.
3. What is the difference between CP-DYNA-2AIO and CP-DYNB-AIO?
Both are 16-channel analog input/output backplanes, but they use different physical configurations. The CP-DYNA-2AIO is Size A and supports MTL4544 and MTL4549Y, whereas the CP-DYNB-AIO is Size B and supports a different set of MTL interface modules.
4. What cable is used to connect the CP-DYNA-2AIO to the control system?
The CP-DYN FTA family uses Tyco Dynamic 20-pin connectors. The CABDYN20 cable series provides the connection between the field termination assembly and the system interface card. The required cable length depends on the installation layout.
