Output Functions
The ADV551-P50 supports three output functions. First, status output provides ON/OFF switching for digital control signals. Second, one-shot pulse output generates a pulse for a set duration. Finally, time-proportioning output controls the ON/OFF ratio over time.
The pulse-width setting ranges from 8 ms to 7200 s, with an 8 ms resolution. However, the additional ON/OFF delay can reach 1 ms, so users should consider this delay when checking timing accuracy for short pulses.
Electrical Characteristics and Field Connections
The module uses current-sink outputs for 24 VDC field circuits. Therefore, users should check the field device’s input requirements and wiring arrangement before connecting the load. The maximum load current is 100 mA per channel at 26.4 V, while the listed load condition is 24 VDC at 50 mA.
The maximum output ON voltage is 2 VDC, and the maximum OFF-state leakage current is 0.1 mA. These values help users check whether connected equipment can recognize the intended ON and OFF states. Also, the specified external supply range is 20.4 to 26.4 VDC.
Ordering Configuration
The complete model number ADV551-P50/D5A00 identifies the output module and its specified interface configuration.
- ADV551: 32-channel digital output module for 24 VDC signals.
- -P: Includes pulse-width output and time-proportioning output functions.
- 5: Without status display and without explosion protection.
- 0: Basic type.
- /D5A00: Specifies the KS cable interface adapter ATD5A-00 for 32-channel digital signals.
Other listed suffix options include -P60, -PE0, and -PF0. These options differ in status display and explosion-protection configuration. Therefore, confirm the full suffix before ordering a replacement, as these configurations are not identical.
Frequently Asked Questions
Q: What output functions does the ADV551-P50/D5A00 support?
A: It supports ON/OFF status output, one-shot pulse-width output, and time-proportioning ON/OFF output. The pulse-width range is 8 ms to 7200 s.
Q: What should users check before connecting field devices?
A: Check the 24 VDC load requirements, current-sink output format, maximum channel current, and input thresholds of the connected devices. Also, confirm that the cable and interface arrangement match the selected configuration.
Q: What does the /D5A00 option mean?
A: The /D5A00 option specifies the ATD5A-00 KS cable interface adapter for 32-channel digital signals. It identifies the connection configuration, not a different channel count.
