4-Digit Up/Down Counter Module - Preset and Relay (25mm Digits)

The Cebek CD-5.1 module is a 4-digit UP / DOWN counter with PRESET function and relay output. 25mm (1.0") high digit LED display. Preset allows you to set a number in count UP mode. Once this number is reach the relay activates and the count stops (ideal for process control automation).

Operation of this model is identical to Cebek CD-8 (available from stock).

The counter starts at zero and increases by one digit (up to a maximum of 9,999) each time a count input is received. It can also count down, subtracting from the count.

Control Inputs - accept simple voltage free make contact closure (e.g. a push button, relay closure) or injection of an external negative going pulse (5Vdc). The 5 control inputs are:

• Count Up - increase count by 1 for each input
• Count Down - decrease count by 1 for each input
• Trigger - sets relay to activate on reaching Preset value (or zero depending on Mode settings below)
• Reset - zeros the count and display
• Next - allows counting on (up or down) when Preset is reached

Programmable Modes - the board can be programmed to operate as follows:

• Preset Number - the number on which the counter will stop (or start)
• Count Mode - start count up from zero or start count down from Preset value
• Relay Activation - either on count equal to Preset value or on count equal to Zero
• Input Frequency Filter - 100 Hz or 4KHz debounce
• Option to save last count number to memory on power loss (close header pins - Jumper not included)

The counter always stops when the count equals the Preset value (or zero depending on mode set). Reset or Next must be used to continue.

Also available with a 13mm high display (Order Code CCD005) and with a 58mm display (Order Code CCD005.2)
