Structurally, all USO modules of the ELPK-03 controller consist of the base unit of module 6 (BOOM) and the functional units of discrete and analog modules installed on it. The BOOM node is a board on which the connectors of MMI, the serial intermodular SPI interface are installed (used to ensure the joint operation of the ITC and MPC modules in multiplexer mode and to check / replace software when setting up the node), an external terminal block for connecting input / output signals and eight slot connectors for the installation of functional units.

Node BOOM is running microprocessor f. Atmel AVR series, which has a fast RISC-system of commands, which allows you to speed up the scanning of functional modules, performing calculations during calibration and obtaining the results of the ADC and provide automatic scanning functions when the modules are in the multiplexer.

Communication with the module of the MPC controller is carried out through the MBP motherboard via a parallel byte interface of the MMI through control registers. MMI is an 8-bit multiplexed data and address bus with an address fixing strobe and read-write gates.

The MPC module constructively consists of a PCB and eight 2-channel input modules of the UOC installed on it, divided into two groups of 8 channels (4 nodes in each group). Each of the groups has a common output GND _.i and GND _.2, respectively, or is powered from its supply voltage U _{pit 1} and U _{pit 2,} respectively. The groups of channels are galvanically isolated from each other and relative to the common controller bus.

The status of the input channels of the module is indicated by LEDs located on the upper part of the UOC units.

The MPC module also provides automatic control of the health of the UOC nodes. Control occurs after each input cycle. If the node is broken (missing), the channel of the node is malfunctioning or another malfunction, the module gives an error code.

The electrical isolation of the channels located on the input nodes of the UOC, relative to the common controller bus and other module nodes (galvanic separation) must withstand a voltage of at least 500 V DC.

The MACC module is designed to convert analog voltage signals into a digital code. Structurally, the module consists of a BOOM and the nodes of the analog-to-digital conversion module of the UAAC installed in it.

One of the modifications of the MACP contains 8 independent measuring channels of analog input, each channel has one analog input. All 8 inputs are galvanically separated. The signal conversion time for all 8 channels into (the time from changing the input signals to outputting values to the MMI channel) is not more than 20 ms.

In another modification of the MACP there are 16 inputs, which is achieved by using 2 analog inputs in each of the 8 measuring channels. 2 groups of 8 inputs are galvanically separated. Signal conversion time over 16 channels in the MATsP-03-16 module (time from change

signals at the input until the values are transmitted to the MMI channel) is not more than 500 ms.

Under normal operating conditions, the limits of the permissible basic reduced error of the MACP channels are not more than 0.1%. The error from the change in the supply voltage ± 10% does not exceed the basic error. Attenuation of general disturbance at a direct current of at least 70 dB. General attenuation at a frequency of 50 (60) Hz is not less than 80 dB.

The MACP module also provides automatic monitoring of the health of the UACP nodes. If the node is broken (missing), the channel of the node is malfunctioning or another malfunction, the module gives an error code.
