ADV551-P50/D5S00

The Yokogawa ADV551-P50/D5S00 is a 32-channel digital output module for the CENTUM VP FIO system. It provides isolated 24 V DC transistor outputs for transmitting ON/OFF control signals to external field devices. This configuration includes the ATD5S-00 pressure clamp terminal block for field wiring and the pushbutton input function.

Output Function and Signal Handling

The ADV551 is designed to convert controller commands into discrete electrical output signals. Its 32 channels provide individual ON/OFF control points for field-side devices. The 24 V DC output arrangement supports discrete control applications where external equipment responds to switching signals.

The module's electrical isolation separates the output signal circuits from the system side. This isolation helps limit the transfer of electrical disturbances between field wiring and the control system.

Electrical Output Characteristics

The ADV551 uses a current-sink transistor output format. Each channel can handle a maximum load current of 100 mA at up to 26.4 V DC. The maximum output ON voltage is 2 V DC, while the maximum leakage current in the OFF state is 0.1 mA.

The external supply operates within a range of 20.4 to 26.4 V DC. The rated applied voltage is 24 V DC, which should be considered when checking the field load and power supply arrangement.

Pulse Width and Time-Proportioning Functions

The -P suffix specifies pulse width output and time-proportioning ON/OFF output functions. These functions allow the module to provide timed switching signals rather than only maintaining a steady ON or OFF state.

• Pulse width range: 8 ms to 7200 s.
• Pulse width resolution: 8 ms.
• Additional ON/OFF delay: Maximum 1 ms.
• Output response time: 3 ms or less for status output; 10 ms or less for mixed status and pulse outputs.

The time-proportioning function supports control strategies that require repeated ON/OFF switching over defined time intervals. Pulse width output uses two consecutive terminals, with the first terminal assigned an odd number.

Terminal Block and Field Wiring

The /D5S00 option specifies the ATD5S-00 pressure clamp terminal block for digital output connections. It provides the field wiring interface for the module without requiring the separate KS cable interface adapter.

The terminal configuration should be checked against the installed output assignment and field wiring diagram. When driving a DC relay, Yokogawa specifies connecting a diode to the load circuit.

Frequently Asked Questions

Q: Is the ADV551-P50/D5S00 a digital input or digital output module?

A: It is a 32-channel digital output module. It sends transistor-based ON/OFF signals to external field devices using a 24 V DC output arrangement.

Q: What is the difference between the -P suffix and the 5 suffix?

A: The -P suffix identifies the pulse width and time-proportioning output functions. The 5 suffix identifies the version without a status display and without explosion protection.

Q: Which terminal block is supplied with the /D5S00 option?

A: The specified terminal block is the Yokogawa ATD5S-00 pressure clamp terminal block for digital output wiring.
