YDO0...-AO (Option A9)
Equipment Supplied
– Interface module
– PCB mountings
– Installation instructions (this manual)
Characteristics
Interface module YDO0...-AO is an analog output port. It can be operated as a current
interface (0/4 – 20 mA, 0 – 24 mA) or as a voltage interface (0 to 10 V). The voltage
supply is internally electrically isolated
The interface module can be configured for any one of the following four modes of
operation:
– Voltage interface, 0 to 10 V
– Current interface, 0 to 20 mA
– Current interface, 4 to 20 mA
– Current interface, 0 to 24 mA
Configuration for intended use is implemented by opening and closing switches.
The arrangement of the switches is displayed in the drawing on the left.
Setting of the applicable operating mode is implemented by setting switches 1 and 2
(switches 3 and 4 have no function):
Operating status
Voltage interface, 0 to 10 V
Current interface, 0 to 20 mA
Current interface, 4 to 20 mA
Current interface, 0 to 24 mA

) The shielding of the connecting cable is connected to the scale housing at one end.
The scale is connected to the protective grounding conductor.
Notes
– Max. load: 390 ohms
– The shielding of the current interface connecting cable is connected to the indicator
housing at one end.
– The scale is connected to the protective grounding conductor.
– If the scale is powered using an internal or external rechargeable battery pack, it is not
possible to operate the current interface.
§ Interface module YDO0...-AO is attached directly onto the digital board of the indicators.
For more information, please refer to the section entitled "Installing in the Indicator".
YDO0...-ETH (Option B9)
Equipment Supplied
– Interface module YDO0...-ETH
– Installation instructions (this manual)
– „Field bus" software interface description for Modbus/TCP operation
Assembly
Connect interface module YDO0...-ETH (Ethernet interface) directly to the digital board
of the scale without configuration. For more information, please refer to the section
entitled "Installing in the Indicator".
Note:
!
Only use cables and plugs that conform to the Ethernet specification (CAT5 or higher).
