87/256 LED Event Counters
The 87/256 LED Event Counter is the most powerful of our large digital LED counters. Standard features include your choice of 4", 6", 8" and 12" tall digits in a 7-segment formation and features a set of inputs consisting of 2 count inputs (jumper selectable sink or source) plus a reset. Non-volatile count memory makes it possible for the counter to retain the last count in the event of a power loss, without battery backup. DIP switches allow the user to select from one of many popular pre-programmed modes of operation. Advanced modes of operation are possible using our FREE Vorne Display-Pro® 4 Windows® programming utility for the 87 Series units. Totalize inputs from one or two sources, with a unique scale factor for each input. Two data inputs allow independent increment/decrement operation or quadrature-encoded inputs standard. Or you can use one of the data inputs on the counter to toggle to a rate display! Preset and trigger capabilities are also standard. The list below defines some of the operational characteristics that can be programmed by a PC using our Vorne Display-Pro® 4 Windows® programming utility. Contact Vorne for specifics at sales@vorne.com.
• Color Changes - Display changes color in a tricolor
display when a process variable such as count reaches a
preset value or as the display scrolls through a sequence of
display items.
• Virtual Displays - Enables a single unit to display up to
4 process variables on the same display through scrolling or
by splitting the display into multiple fields.
• Define Range Restrictions - Define the minimum and maximum
allowable display value and take action if a limit is
reached such as stop, flash the display value or flash a
predefined string.
• Define an Address - An address is defined for networking
applications.
• Define Inputs - Define an active level for each individual
input and debounce time.
• Preset and trigger - Unit takes special action if a preset
value is reached such as activating an optional relay,
flashing the display value, reloading a predefined “initial
value”, stop, change color for tricolor displays, and/or
transmit a predefined string.

77 Series LED Counters
The 77 Series is the most economical of our large digital LED counters. Standard units feature 3.3" tall digits in a 7-segment formation and include 2 sets of inputs, one set for common sinking operation and the other for isolated 120/220 VAC input. Each set of inputs includes one count input and one reset input (a second count input is optionally available). A regulated output voltage of 12 VDC is provided for auxiliary use (optional 5VDC replaces 12VDC). 77 Series LED counters are sold as models 77/256M (no preset) and 77/215 for applications requiring a preset.

77/256M LED Event Counters
The Vorne 77/256M LED Event Counter displays the number of inputs received on a 2 to 6 digit display field. Non-volatile count memory makes it possible for the 77/256M to retain the last count in the event of a power loss, without battery backup. The 77/256M can be equipped with an optional scale factor of 0.0001 to 9999, settable via internal DIP switches. The displayed value is the product of the scale factor and the total count.
