    4. Analog input In the M2000 series remote I/O module, except M2002 cannot switched input type, the other module voltage/Current switchable. Each channel has a Jumper bit to set the input type for that channel. When the Jumper is not connected, this channel is a voltage input channel;...
  • Page 19 At the leave factory, these Jumper positions will be set according to the default input range. The default range is marked on the front panel of the module, as shown in the figure below. The default range is 0~10V, so there is no Jumper wire connected inside. If you need to measure a 20mA Current signal, you need to open the housing and plug in the Jumper cap on the corresponding channel.
