Outputs
The outputs of the EK280 are designed as
"open collector - transistor - outputs".
So that the internal battery is not placed under
undue load, it is standard for the isolation of the
outputs (galvanic separation) to be deactivated
(see Chapter 6.8).
The outputs are generally not suited to
switching larger external loads (limit values: see
chapter "Technical data" in the operating
instructions)!
Various instruments can be connected to the digital output of the EK280. The outputs are
preprogrammed for this purpose.
The following functions are preprogrammed for the outputs as factory settings:
Output
Function
DA1
Pulse output for the total volume at base conditions "VbT" (cp.O1=0.1)
DA2
Pulse output for the total volume at measurement conditions "VmT" (cp.O2=0.1)
DA3
Status output for warnings (see Chapter 10.2)
DA4
Status output for alarms (see Chapter 10.2)

Connection of outputs
Danger!
For EK280 with internal power supply, the mains voltage must be switched off before
opening the housing, ensure it is not turned back on and verify that there is no voltage.

Connected device
e.g. DL230
Connect the device to one of the desired digital outputs (terminals "DA1" to "DA4") on the EK280.
