OPERATION DESCRIPTION

The measurement of the digital input frequency or the totalizer value is translated into an analogue or digital output signal. 

The frequency value or alternatively the totalizer value can also be viewed via the display; in the 11-digit model (4 + 7) both 

values can be displayed simultaneously (4 digits: frequency value, 7 digits: totalizer value). The values are also available 

via MODBUS-RTU protocol from the RS485 port (via optional board). 

Setting mode:

All the parameters of the instrument can be set via the Programming Menu or RS485 (via optional board). The alarm 

thresholds can also be set quickly via the specific Quick Alarm Menu. The dedicated Easy Setup software for programming/

configuring the module was also developed (see www.seneca.it). 

Retransmission mode:

The instrument accepts the following retransmission modes:

Analogue output:

 The measurement of the frequency of the digital input is translated into an analogue output signal 

(current or voltage).

Digital output:

 The output generates an impulse every time the totalization is increased or decreased. A pulse of duration 

≥ ~ 100 ms is generated. The output follows the totalizer up to the maximum value of approximately 4.7 Hz. As the counting 

frequency increases (up to the maximum value shown above), pulses are gradually lost until an output is obtained always at 

a low logic level. The output is normally high.
