Description
D9E
Digital frequency output, measure
Measurement value is translated to a frequency within given frequency range.
The default frequency range to represent 0…100% flow is 0…10000 Hz. Any other frequency range must be
specified on order.
F9B
Digital pulse output, batch counter
Pin 5 is pulled down to 0Vdc when a given batch size is reached (during a given pulse length).
By default, a pulse is given at each 1x the
Counter unit
batch value, with a pulse length of 1 second. For
instance, when
Counter unit
is set to 'ln', a pulse is given each time 1 ln has passed through the instrument.
An alternative pulse length must be specified on order.
Provide a pull-up resistor of 5…10 kOhm to create 15…24 Vdc at pin 5 (according to the applicable hook-up
diagram).
I3C
Digital input, controller mode valve close
Valve closes when pin 5 is connected to 0 Vdc.
This option switches between the default
Control mode
and mode ‘Valve Close’ (value 3). When the default
Control mode
is digital, the default value is 0 (bus/RS-232), when the default
Control mode
is analog, the
default value is 1 (Analog input).
I8C
Digital input, controller mode valve purge
Valve is fully opened when pin 5 is connected to 0 Vdc.
This option switches between the default
Control mode
and mode ‘Valve Fully Open’ (value 8). When the
default
Control mode
is digital, the default value is 0 (bus/RS-232), when the default
Control mode
is analog,
the default value is 1 (Analog input).
I1R
Digital input, reset counter
The counter resets when pin 5 is connected to 0 Vdc.
I2R
Digital input, reset alarm
The alarm resets when pin 5 is connected to 0 Vdc.
*) Notes regarding controller options:
·
A controller output option (A1V, B1V or B2V) can only be installed in combination with controller mode A or D
(controller enabled, see model key).
·
If the controller is enabled, the M8 connector can always be used to control a Bronkhorst® valve (through pin 3).
·
Although it is theoretically possible to have 3 controller options installed, no more than 1 signal should be used at any
time.
