The binary inputs from DI4 to DI7 can be configured in the mode of analogue inputs (then they are processed as analogue inputs AI0 to AI3) with an input range of 0 ÷ 10 VDC, or with a 500 Ω shunt wired in parallel with the respective input allows the measurement of current 0 ÷ 20 mA or 4 ÷ 20 mA.
The voltage signals 0 ÷ 10 V are connected directly to the terminals (positive terminal to AIx and negative to GND).
The current inputs require an external shunt 500 Ω, which can be implemented using the shunt MT-1690 (see Fig.1), which can be ordered separately. The outlets of the MT-1690 shunt are inserted directly in the terminals together with the connecting cables. The unused outlets of the shunt can be broken off and the respective inputs can be used as binary or voltage inputs.
The SW configuration is performed in the Mosaic programming environment. The shunt outlets for those inputs, which are not required for the measurement of current signals, should be broken off. The inputs are passive, i.e. they must be connected to an external power supply of current loops (see Fig.1).
