The heart of smart control Inteli DC 4/4 module is an extension module, transducer type, equipped with analog inputs and analog outputs. The module can be used with various types of controllers, purposed for applications where we need to measure precisely direct voltage and direct current (DC Voltage, DC Current) > Unipolar voltage measurement and bipolar current measurement per channel > 2 galvanically isolated input measuring channels Analog Inputs > 4 channels-2 for Voltage and 2 for Current measurement » Voltage measurement input up to 1500 VDC -direct measurement » Current measurement with external shunt up to 3000 ADC (100 mV max voltage input from external shunt resistor) Analog Outputs > 4 channels - 2 for Voltage and 2 for Current measurement » 4 .. 20 mA current loop output (see the transfer function section) | Related SWver: 1.0.0 | Date of issue: 3/25/2024

3 Wiring 3.1 Measure: HV Bus Voltage and Current (SHUNT) The module I-DC4/4 allows to measure high bus voltage and current. Wiring for such measurement is shown on Image 4.1. Current is measured via an external shunt resistor. Information of a measured values is provide via current loops. Detailed information can be found in Global Guide. Image 4.1 SHUNT wiring scheme The shunt resistor for current measurement should be connected in the positive pole of a HV bus. On the Image 4.2 configuration is illustrated for current measurement via the external shunt resistor in the negative pole of the HV...

Image 4.2 SHUNT in negative branch When current loops are read by a ComAp controller the negative power supply terminals of both the modul IDC4/4 and the controller should be interconnected. This allows the return current to flow back to the module (closed current loop). 3.2 Isolated floating current loop measurement When the current loops are measured by an isolated (floating) external unit the return current cannot flow back to the module via the negative power supply terminal. In such case the external unit must be connected to the terminal 4 (COM) so the current loops are properly closed,...
