E-78 S
E-78 SERIES
TIMER / COUNTER &
SPEED INDICATOR
E-78 D
■ DESCRIPTION
The E-78 Series instruments are designed using new generation
micro-controllers. The instruments are used for pulse
counting, timing, frequency, period, speed measurements and
similar applications. Instrument dimensions are 72x72 mm
panel size conforming to IEC 668.
E-78 Series instruments can be connected to PNP or NPN
sensors and all kinds of incremental encoders. Timer/counter
mode, number of pulses corresponding to one unit, up or
down counting and reset functions can be programmed from
the front panel.
E-78 S Series has 2x4 Digit LED display for time/count and set
value.
E-78 D Series has 4 Digit LED display for frequency, period or
speed indication.
