Overview
Output Characteristics
The ADV551 uses a current-sink output format. Each channel switches a 24 VDC field signal, with a maximum ON-state voltage drop of 2 VDC and an OFF-state leakage current of 0.1 mA. Furthermore, the module provides output isolation between the signal circuits and the system.
The module supports three output functions:
- Status output: Provides standard ON/OFF digital signals.
- Pulse width output: Generates one-shot pulses with adjustable widths.
- Time-proportioning output: Controls ON/OFF timing according to a configured time proportion.
Pulse Output and Response
The pulse width range is 8 ms to 7200 s, with an 8 ms resolution. An additional ON/OFF delay of up to 1 ms applies to pulse width settings. Meanwhile, the output response time depends on the selected function: status output responds within 3 ms, while mixed status and pulse output responds within 10 ms.
Connection and Electrical Requirements
The /D5A00 option identifies the KS Cable Interface Adapter for 32-channel digital signals, model ATD5A-00. The module also supports connection through a dedicated AKB331 cable or a MIL connector cable. Therefore, the interface arrangement and existing cable configuration should be checked when selecting a replacement.
The output circuits have a withstand voltage of 2 kV AC for one minute between the output signals and the system. The test applies to the common minus (-) side of each 16-channel group.
