6DI-1AO
6 Analog/Digital Inputs to 1 Analog Output Board for Binary Signal Conversion
- Monitors multiple contacts with one output: The ACI/6DI-1AO is designed to monitor two to six door, window, or dry-contact inputs and send a single resistance output to the control system.
- Ideal for open/closed status applications: Use it to track door and window position, access points, equipment contacts, or other status signals in building automation systems.
- Weighted resistor network output: Each contact produces a unique resistance value, allowing the controller to identify contact status through a resistance input.
- Efficient controller integration: Combines up to six digital contact points into one analog resistance signal, helping reduce the number of controller inputs required.
- Clear diagnostic values: All contacts closed read 0 Ω, while all six contacts open read approximately 31,779 Ω, supporting fast troubleshooting and verification.
- Simple installation: Ships with snap-track mounting and includes four board mounting holes for flexible panel or enclosure installation.
- Service-friendly wiring: Separate terminal blocks for each contact input and the controller resistance output make wiring and maintenance straightforward.
- Reliable retrofit solution: Useful when existing control systems need contact monitoring through a resistance-based input instead of multiple discrete inputs.

Supported Applications
The ACI 6DI-1AO is a specialty signal conditioner designed to monitor two to six digital inputs representing normally-open (N/O) dry contacts. The unit converts the state of these binary inputs—such as door or window open/closed positions—into a single resistance output for transmission to a control system that accepts resistance input.
Operating Conditions & Performance
The board operates within an ambient temperature range of 32 to 140°F (0 to 60°C) and supports relative humidity from 5 to 95% RH Non-Condensing. The output signal provides a resistance range of 0 to 31,779 Ohms with an accuracy of +/-2%. Each unique combination of the six inputs results in a distinct total resistance value, enabling up to 64 discrete output values.
Configuration Options
The series is configured as a single model: ACI/6DI-1AO. Key technical specifications include:
- Inputs: Two to six sets of N/O dry contacts (normally-open).
- Output Signal: Resistance output ranging from 0 to 31,779 Ohms.
- Contact Resistance Values: TB1=499Ω, TB2=1KΩ, TB3=2KΩ, TB4=4.02KΩ, TB5=8.06KΩ, TB6=16.2KΩ.
- Electrical Connection: Terminal block (TB1-TB6 for contacts, TB Output for controller input).
- Mounting Options: Includes a snap track; the circuit board also features four .156” diameter mounting holes for alternative installation methods.
Key Product Differences
The 6DI-1AO is offered as a single configuration with fixed input and output parameters. The model number structure reflects this singular option set (e.g., 6DI - 1AO). No additional segments, optional accessories, or alternative housing configurations are documented for this series.
