YDA01M-20MA (Option A9)
Characteristics
The YDA01M-20MA interface module is an analog output port. This module can be
operated as either a current interface (0/4 - 20 mA, 0 - 20 mA) or a voltage interface
(0 to 10V. The internal power supply is electrically isolated
1) ).
The interface module can be configured for any of the following 4 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):
Operating status Switch
Voltage interface, 0 to 10 V SW 1–1: closed = “ON",
SW 1–2: open
Current interface, 0 to 20 mA SW 1–1: open,
software 1–2: closed = “ON"
Current interface, 4 to 20 mA SW 1–1: open, software 1–2: open
(factory setting)
Current interface, 0 to 24 mA SW 1–1: closed = “ON"
SW 1–2: closed = “ON"
1 ) The shielding in the connecting cable is connected at one end to the housing of the display and control unit.
The display and control unit is connected to the protective grounding conductor.
– Max. load: 390 ohms
Notes
– The shielding in the current interface connecting cable is connected at one end to the
housing of the display and control unit.
– The display and control unit is connected to the protective grounding conductor.
– If the display and control unit is operated with a rechargeable battery, operation of the
current interface is not possible.
§ The YDA01M-20MA is installed directly on the digital PCB in the Midrics display and
control unit. For details, please see “Installation in the Display and Control Unit."
