*1: The output contacts are A type (NO: Normally Open), and SDV144 status contacts are B type (NC: Normally Close).
*2: If the ON pulse diagnosis for SDV541 is enabled and the SDV541 output status is set to OFF, the LED goes ON for each ON
pulse output.
When SDV144 is connected to SRM54D, Detect Disconnection and Detect Short Circuit
should be disabled on I/O Parameter Builder
.
