Yokogawa ADV561-P00 Digital Output Module

Configured for high-density digital signal switching and pulse execution in CENTUM VP platforms, the Yokogawa ADV561-P00 (ADV561 Digital Output Module) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

Note: Suffix position 2 option codes include "5" (Without status display; no explosion protection) or "E" (Without status display; with explosion protection). Suffix position 4 option codes include "0" (Basic type) or "4" (With ISA Standard G3 option).

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The module incorporates robust channel-to-channel isolation networks designed to prevent parasitic ground loops across large digital output banks. Operating within standard DCS I/O racks, the galvanically isolated output paths protect sensitive backplane electronics from field-side voltage transients up to 2 kV AC. Cold junction compensation and precise current loop regulation across neighboring analog and digital channels ensure noise immunity and stable signal execution across high-density field interface wiring.

Frequently Asked Questions

Q: What precautions must be taken regarding common terminals during field wiring?

A: Common negative (-) terminals are grouped every 16 channels. The isolation withstand voltage between distinct commons is rated at 600 V AC for 1 minute; wiring across different commons must not exceed this potential difference.

Q: Can the ADV561-P00 handle high-speed pulse width generation without host CPU overhead?

A: Yes. The onboard hardware executes pulse width timing from 8 ms to 7200 s with an 8 ms resolution directly at the module level, relieving the central control station CPU of high-frequency timing tasks.

Field Installation Guidelines

1. Power down the external 24 VDC power supply prior to connecting or disconnecting the AKB397 or MIL connector cables to prevent pin arcing.
2. Ensure field cable shields are bonded to protective earth at a single point to prevent high-frequency noise injection into the current sink channels.
3. Observe the total current limits per 16-channel common group to ensure backplane trace temperature limits are not exceeded during continuous output operation.
4. Verify that the external 24 VDC field supply stays within the required 20.4 to 26.4 VDC operating window under full load conditions.
