ONNECTING THE MODEL
HD35EDWH
WITH TERMINAL HEADER INPUTS
HD35ED[L]WH model has four terminal header inputs. Each input can be configured as a
Pt100/Pt1000, thermocouple, 0/4…20 mA (shunt resistance inside), 0…50 mV, 0…1 V, 0…10 V or
potentiometric input. Only input 4 can be also configured as pulse counter (count of voltage-free
contact switchings).

If a channel is configured as 0-10 V input, set the switch on the terminals of the channel to
0-10V. In all other cases, set the switch to 0-1V.
If a channel is configured as current input, insert the 50
Ω shunt resistance closing the jumper
placed above the terminals of the relevant channel. In all the other configurations, leave the
jumper open.
Fig. 9.5.2: shunt resistance for current input
The current input accepts any value in the range 0 to 20 mA.
Configuration of inputs is done with the HD35AP-S software (see software instructions).
