X67AO1323 4-Channel Analog Output Module 0-20 mA

Product Overview

The X67AO1323 (X67AO1323) is a ruggedized, field-mounted analog output module designed for decentralized automation environments. Featuring four high-precision outputs with a 0 to 20 mA signal range, this module is engineered to control actuators, variable frequency drives, and proportional valves directly at the machine level. With a 12-bit converter resolution and integrated reverse polarity protection, the X67AO1323 ensures reliable and stable signal transmission. Its IP67-rated construction (typical of the X67 series) makes it an ideal solution for harsh industrial conditions where cabinet space is limited and decentralized I/O is required to reduce wiring complexity and signal interference.

Technical Configuration

The hardware architecture of the X67AO1323 is optimized for 24 VDC power systems, operating efficiently within a broad voltage range of 18 to 30 VDC. The module utilizes a 12-bit digital-to-analog converter (DAC), providing a granular resolution of 4096 steps across the 0 to 20 mA range for smooth control loops. To ensure equipment safety, the module includes comprehensive protection against reverse polarity. Its thermal design is rated for extreme industrial temperatures, from -25 to 60 deg C, allowing it to be mounted directly on machinery in diverse climates. The high actuator power supply capacity of up to 12 W ensures that even demanding field devices receive consistent power without the need for additional auxiliary supply lines.

Technical Specifications

Technical FAQs

Does the X67AO1323 require a separate power supply for the actuators?

The module is designed to provide power to the connected actuators directly through the X67 bus connection, up to a maximum of 12 W. However, you must verify that the total power consumption of all 4 connected devices does not exceed this 12 W limit to ensure stable operation.

How is the 12-bit resolution calculated for the 0-20 mA range?

The 12-bit resolution provides 4096 discrete steps. This means each step represents approximately 0.00488 mA (4.88 microamps). This level of precision is typically sufficient for most industrial flow control, speed regulation, and positioning tasks.

Is this module suitable for outdoor or washdown environments?

As an X67 series component, this module is built for field installation. While its operation temperature is broad (-25 to 60 deg C), ensure that all M12 connectors and unused ports are properly sealed with caps to maintain its environmental integrity against moisture and dust ingress.

Engineering & Installation Guide

• Signal Shielding and M12 Connections: To maintain the 12-bit signal accuracy and prevent EMI interference, use shielded M12 cables for all analog outputs. The cable shield must be properly grounded through the M12 connector housing to the machine frame to ensure a low-impedance path for high-frequency noise.

• Thermal and Mounting Considerations: Although the module is rated for up to 60 deg C, ensure it is not mounted directly against high-heat sources like large motors or industrial ovens. Natural convection should be allowed around the module housing to prevent localized overheating, especially when utilizing the full 12 W actuator power capacity.

• Reverse Polarity and Wiring Safety: While the module features integrated reverse polarity protection for the 24 VDC supply, always verify the pinout of your M12 cables before applying power. Incorrect wiring of the current loop (0-20 mA) can lead to erratic actuator behavior or potential damage to the connected third-party devices.
