Therefore, this module suits applications requiring precise timing control and proportional output signals.

Technical Specifications

Output Channels

The module provides 32 output channels for controlling external devices. Each channel delivers reliable switching performance. The output format is current sink , meaning the module switches the negative side of the load to ground.

Voltage Ratings

The rated input voltage is 24 V DC . Similarly, the load voltage is 24 V DC at 50 mA . The external power supply voltage range spans 20.4 to 26.4 V DC , accommodating typical industrial power variations. The output ON voltage maximum value is 2 V DC . When the output is OFF, the leakage current maximum value stays at 0.1 mA . Furthermore, the maximum load current reaches 100 mA per channel at 26.4 V .

Output Functions

The module supports three key output functions. Status output provides ON/OFF status output for basic discrete control. Pulse width output delivers one-shot pulse width outputs for timed operations. Time-proportioning output generates time-proportioning ON/OFF signals for analog-like control. Consequently, the ADV551-P50/D5A00 handles both simple and complex control tasks.

Output Response Time

The output response time depends on the selected operating mode. For status output operations, the response time measures 3 ms or less . When mixing status and pulse outputs, the response time extends to 10 ms or less . Consequently, these fast response times suit applications requiring quick output updates.

Pulse Width Specifications

The pulse width ranges from 8 ms to 7200 seconds , offering tremendous flexibility. Resolution for pulse width settings is 8 ms . However, an ON/OFF delay of up to 1 ms adds to each transition. This wide range accommodates both high-speed pulsing and long-duration timed outputs.

Withstanding Voltage

Between output signal and system, the withstanding voltage reaches 2 kV AC for 1 minute . Between commons (common minus side every 16 channels), the rating is 500 V AC for 1 minute . These high isolation ratings protect the system from field wiring faults.

Current Consumption

The internal 5V DC rail draws a maximum of 700 mA from the system backplane. Meanwhile, the external power supply draws only 60 mA from the 24V DC field power source. This low power draw minimizes load on both the system power supply and the field power supply.

Suffix Codes

The ADV551-P50/D5A00 carries three meaningful suffix codes. Suffix Code P indicates the module includes pulse width output and time-proportional output functions. With Suffix Code 5 , the module comes without status display and with no explosion protection. Finally, Suffix Code 0 designates the basic type configuration. Therefore, this digital output module suits standard industrial environments without hazardous area requirements.

Option Code

The /D5A00 option includes a KS Cable Interface Adapter (Model ATD5A-00) for 32-channel digital connections. This adapter simplifies cabling between the module and field devices.

External Connection Options

The module supports three distinct external connection methods. Pressure clamp terminals provide tool-less wire connections for quick field terminations. A dedicated cable (AKB331) offers a pre-assembled wiring solution that reduces installation errors. MIL connector cable , on the other hand, allows quick disconnect capability for high-density applications requiring frequent maintenance. Each method suits different installation requirements and field conditions.

Installation Guide

Follow these steps to install your ADV551-P50/D5A00 correctly.

1. Power Down the System: Disconnect power from the chassis. This prevents electrical damage during installation.

2. Select a Slot: Choose an available I/O slot in your Yokogawa system. Ensure adequate clearance for wiring.

3. Insert the Module: Align the ADV551-P50/D5A00 with the slot guides. Push firmly until the module seats into the backplane connector.

4. Secure the Module: Tighten the retaining screws at the top and bottom. This secures the digital output module in place.

5. Install the KS Cable Adapter: If using the /D5A00 option, mount the ATD5A-00 adapter first. Then, connect the adapter to the module using the KS cable.

6. Connect Field Wiring: Wire your field devices to the appropriate output terminals. Choose from pressure clamp terminals, AKB331 cable, or MIL connector based on your needs.

7. Apply External Power: Connect an external 24 V DC supply (20.4 to 26.4V) to the module. This powers the output circuits.

8. Apply System Power: Restore power to the chassis. Verify the module powers up without errors.

9. Configure Outputs: Set up your output functions (status, pulse width, or time-proportioning) using your system configuration software.

10. Test Operation: Activate each output channel individually. Confirm that each field device responds correctly.

Frequently Asked Questions (FAQ)

1. What is the difference between status output and pulse width output?
Status output provides simple ON/OFF control for loads like relays and indicator lights. In contrast, pulse width output generates timed pulses ranging from 8ms to 7200 seconds. Therefore, the ADV551-P50/D5A00 supports both basic and timing-critical applications.

2. What does the /D5A00 option include?
The /D5A00 option includes a KS Cable Interface Adapter (Model ATD5A-00) for 32-channel digital connections. This adapter significantly simplifies cabling between the module and field devices.

3. Can I use this module without external power?
No, the ADV551-P50/D5A00 requires an external 24 V DC power supply (20.4 to 26.4V) to drive output loads. The module draws 60 mA from this external supply, plus 700 mA from the internal 5V rail.

4. What is the maximum load current per channel?
Each channel can handle up to 100 mA at 26.4 V . For reliable operation, stay within this limit for all 32 channels simultaneously. Consider derating if ambient temperatures exceed standard conditions.

5. What is the purpose of the time-proportioning output function?
Time-proportioning output generates ON/OFF signals where the duty cycle varies proportionally to a control value. This function simulates analog output control using a digital output. Consequently, it proves ideal for temperature control and similar closed-loop applications.
