On May, 2020 the Transconverter design office successfully completed development and operational testing of BI 3.3 interface unit.
The BI-3.3 unit is meant to form 3 output digital signals affected by commands that come through CAN interface from an external control system. Upon that the BI 3.3 unit provides processing and transmission of 3 input digital signals through CAN interface to an external control system.
The BI 3.3 unit contains 3 digital outputs which have a permissible switching voltage 160 V DC at current 100 mA and at switching period no less than 2 msec. All the output channels have a common positive potential.
Also BI-3.3 unit contains 3 digital inputs which have input voltage from 20 to 30 V DC at useful current no more than 30 mA and switching period no less than 50 msec. All the output channels have a common negative potential.
