DIGITAL ELEMENT 1(48)
There are 48 identical digital elements available, numbered 1 to 48. A digital element can monitor any FlexLogic operand
and present a target message and/or enable events recording depending on the output operand state. The digital element
settings include a name which will be referenced in any target message, a blocking input from any selected FlexLogic oper-
and, and a timer for pickup and reset delays for the output operand.
• DIGITAL ELEMENT 1 INPUT: Selects a FlexLogic operand to be monitored by the digital element.
• DIGITAL ELEMENT 1 PICKUP DELAY: Sets the time delay to pickup. If a pickup delay is not required, set to "0".
• DIGITAL ELEMENT 1 RESET DELAY: Sets the time delay to reset. If a reset delay is not required, set to “0”.
• DIGITAL ELEMENT 1 PICKUP LED : This setting enables or disabled the digital element pickup LED. When set to
“Disabled”, the operation of the pickup LED is blocked.

CIRCUIT MONITORING APPLICATIONS:
Some versions of the digital input modules include an active voltage monitor circuit connected across form-A contacts. The
voltage monitor circuit limits the trickle current through the output circuit (see technical specifications for form-A).
