15.4 8-point/16-point relay-output module
RELAY OUTPUTS WELDED CLOSED
• Always protect relay outputs from inductive alternating current load damage using an
appropriate external protective circuit or device.
• Do not connect relay outputs to capacitive loads.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
