The Delta AS08AN01R-A is a digital output module providing eight individual relay outputs for controlling external devices. It allows a PLC to switch higher power loads than would be possible with transistor outputs.

This module acts as an interface, translating low-voltage PLC signals into high-voltage or high-current signals required by machinery, such as motors or solenoid valves. Its relay contacts offer electrical isolation, protecting the PLC from voltage spikes and surges from the controlled equipment.

The eight relay outputs are rated for 2A per point and 8A common, making them suitable for a wide range of industrial applications including lighting, heating elements, and small motor control.

Q2: What is the voltage and current rating for the Delta AS08AN01R-A?

The module supports a wide input power supply range, accepting either 10 to 240 VAC or 5 to 24 VDC. This flexibility accommodates various power sources in industrial environments.

Each individual relay output can handle up to 2A. The common terminal for all eight outputs is rated for a maximum of 8A. It is crucial not to exceed these limits to prevent damage or premature failure.

The relay contacts are designed for switching both AC and DC loads within their specified current and voltage limits, typically up to 250 VAC or 30 VDC.

Q3: Can the Delta AS08AN01R-A be used with AC and DC loads?

Yes, the relay output type of the AS08AN01R-A allows it to switch both AC and DC loads. This versatility is a key advantage over solid-state output modules.

When controlling DC loads, ensure the voltage does not exceed 30VDC and the current does not exceed the 2A per point rating. Proper polarity must be observed when wiring DC loads.

For AC loads, the module can handle up to 250VAC, provided the current remains within the 2A per point limit. The common terminal must be correctly wired according to the specific load configuration.

Q4: How do I wire the Delta AS08AN01R-A module?

Wiring involves connecting the common (COM) terminal and the individual output terminals (Y0 to Y7) to your external devices. The power supply for the module itself connects to the designated power terminals.

Use single-core or multi-core cables within the 24-22 AWG range for connections. Ensure all connections are secure, especially with the spring-clamp terminal blocks, to prevent intermittent contact.

Always consult the AS Series Hardware Manual for precise wiring diagrams, as configurations may vary slightly depending on the specific PLC CPU and system setup.

Compared to transistor output modules (like NPN or PNP types), the AS08AN01R-A offers the advantage of higher current handling and the ability to switch AC loads, along with electrical isolation.

Transistor outputs are generally faster and have a longer lifespan due to the absence of mechanical contacts, making them suitable for high-speed switching applications where AC switching is not required.

The choice between relay and transistor outputs depends on the specific application requirements, such as load type, voltage, current, switching speed, and the need for electrical isolation.

Q9: What are common troubleshooting steps for the AS08AN01R-A?

Begin by verifying that the module is receiving the correct power supply (10-240 VAC or 5-24 VDC). Check wiring connections for looseness or damage.

Use the PLC programming software to check the status of the output points. Ensure the logic is correctly commanding the outputs to activate and that there are no programming errors.

If a specific relay fails to activate, you can manually test the relay by applying a suitable voltage to its coil terminals, listening for a click. However, exercise extreme caution during such tests to avoid electrical shock.
