Product Type: Communication Preset Counter

The E21 Series is a DIN 72 x 72 preset counter + tachomter with communication capability. This counter is fully programmable and can handle complex manufacturing processes including multi-step operations such as batching, cut to length, packaging, etc. The E21 series has a dual line 6 digits LED display. The upper line display is a RED LED, 10.0 x 5.5mm figure size that displays Count values (preset, batch, total) and Tachomter. The lower line display is a GREEN LED, 8.0 x 4.0mm figure size that displays the Preset values.

The E21 series is powered by AC100 - 240V and an external power supply of DC12V is available for sensors. This counter can accept Contact, Open Collector or DC Voltage input signals and count modes includes Add, Subract, Add/Subract and Quadrature (bidirectional) and count speed is selectable from 30Hz - 8kHZ. The unit has a built-in output relay which actuates when preset values are reached. NPN Open Collector output is also available. Operation modes and Output modes are also programmable to suit any complex process. Reset can be done via the front reset button or remotely.

The front panel has LED indicators for easy identification of what is the current display. Other programmable features are Prescale, Decimal Point Position, Key Lock and Initial vale at resetting. The E21 Series also has a built in EEPROM memory for count value and settings retention even during sudden power loss. This counter uses a RS-485 Serial interface for data communication. Wiring connections are secured thru the terminal screw connection.
