2.1.4.2 Description

The counter module also can be ordered as frequency counter module with
750-404/000-003.
The counter module 750-404/000-003 measures the period of the 24 V DC
input signal at the input CLOCK and converts it into a corresponding
frequency value. The measurement is enabled if the input GATE is an open
circuit input or 0V. To disable processing, the GATE input is to be set to 24 V
DC.
To recognize low frequency or near zero frequency signals, the maximum
time between two data updates is parameterizable.
The digital outputs DO1 and DO2 can be activated via specific bits in the
Control byte.
The outputs are short-circuit-protected.
The high states of the inputs GATE and CLOCK and the output channels are
each indicated by a LED.
An optocoupler is used for electrical isolation between the bus and the field
side.
Any configuration of the counter modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
