LOGIC INPUTS
The logic inputs are insulated from the instrument through optocouplers.
The connection cables of the logic inputs must not be channeled with power cables.
Use a shorter connection cable as possible.
To activate a logic input, it must be brought to the positive of a 24Vdc power supply while
the common item must be connected to its negative. The function of the inputs is established
in the relevant Setup menu.
LOGIC OUTPUTS
The 6 logic outputs are of the Photorelay (dry contact) type with a common item. The capacity of each
contact is 100 mA / 30Vdc. By enabling the output, the contact closes (NA contact).
The environment where the equipment is installed can normally be subject to strong magnetic
fields and electrical noise caused by the machinery present, so it is advisable to implement
the usual precautions in order to avoid that these affect the typical signals of a precision
electronic equipment. (filters on contactor, diodes on 24 Vdc relays, etc.)
The connection of the outputs is shown below
