YDA01M-20MA (Option A9)
Features
Interface module YDA01M-20MA is an analog output port. It can be operated as a current
interface (0/4 – 20mA, 0 – 24 mA) or as a voltage interface (0 to 10 V). The voltage supply is
internally galvanically isolated.
It is delivered with the PCB in 4-20mA operating state.
The interface module can be configured for any one of the following four operating states:
– Voltage interface, 0 to 10 V
– Current interface, 0 to 20 mA
– Current interface, 4 to 20 mA
– Current interface, 0 to 24 mA
Configuring the module for the intended use involves opening and closing certain switches.
The positions of the switches are indicated in the drawing on the left.
The operating state is defined by the configuration of switches 1 and 2 (switches 3 and 4
have no function):
– Max. load: 390 ohms
Notes
– The screen of the current interface connecting cable is connected to the indicator housing at
one end.
– The indicator is connected to the protective grounding conductor.
– If the indicator is powered using an internal or external rechargeable battery pack, it is not
possible to operate the current interface.
§ Interface module YDA01M-20MA is attached directly onto the digital PCB of the Midrics
indicators (MIS..., MW...). For more information, please refer to the section entitled
"Installing in the Indicator".
Example: Connect platform with 20 kg max. load Multimeter to terminal 1 and 2 on the
terminal block.
§ Configure switch SW 1 before switching on the device
§ Configure the SW switch on the YDA01M-20MA PCB.
SW1 and SW2 ON = 0mA at 0 g and 24mA at 20 kg
§ Switch on the Midrics, the scale is adjusted.
§ Select in the Unicom/ Analog/ menu.
§ When no load is on the weighing pan, 4 mA should be displayed on the Multimeter and
20mA under max. load. If these values should deviate, the value can be preconfigured in
the menu under Setup / Unicom / Analog/ 8.16.1 and 8.16.2.
§ Select 8.16.1 (lower value). Midrics now generates a current requirement of approx. 3.99
mA on the Multimeter; enter this value on the keypad.
§ Select 8.16.2 (upper value). Midrics now generates a current requirement of approx.
20.00 mA on the Multimeter; enter this value on the keypad.
§ Exit menu and verify with weights.
