Electromagnetic Flowmeter COPA-XT
Binary Output (terminals V8, V9)
The output can be configured as a pulse or system alarm
output. The output conforms to the Standard VDI/VDE 2188.
Scaled Pulse Output (terminals V8, V9)
Scaled pulse output max. 100 Hz, pulse factor between
0.001 and 1000 as a multiplier for the value indicated in the
display (1 pulse/m
3
* 1000). The pulse width can be set from
0.100 ms to 2000 ms.
Contact Output (terminals V8, V9)
The following functions can be assigned in the software:
System Monitor closed or open contact
Forward/Reverse, closed for forward flow direction
Max-Alarm, Min-Alarm, closed or open contact
HART-Protocol
The HART-Protocol provides for communication between a
process control system or handheld terminal and an EMF field
instrument. The digital communication utilizes an AC signal
superimposed on the current output which does not affect any
other instruments connected to the current output circuit.
