There are 16 identical Digital Elements available, numbered 1 to 16. A Digital Element can monitor any FlexLogic™ oper-
and and present a target message and/or enable events recording depending on the output operand state. The digital ele-
ment settings include a 'name' which will be referenced in any target message, a blocking input from any selected
FlexLogic™ operand, 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".

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).
As long as the current through the Voltage Monitor is above a threshold (see Technical Specifications for Form-A), the Flex-
Logic™ operand "Cont Op # VOn" will be set. (# represents the output contact number). If the output circuit has a high
resistance or the DC current is interrupted, the trickle current will drop below the threshold and the FlexLogic™ operand
"Cont Op # VOff" will be set. Consequently, the state of these operands can be used as indicators of the integrity of the cir-
cuits in which Form-A contacts are inserted.
