Redkoh Industries RK2000 1.42 2029001-A Interface Unit

Redkoh Industries RK2000 Interface Unit, part number 2029001-A, is a preowned module in the RK2000 Microprocessor Transformer Rectifier Control system that serves as the interface between analog control signals and the digital logic used to fire SCRs in precipitator power circuits. The unit houses the SCR firing circuit and provides the interface between the control and feedback signals and the keypad/display unit, with on‑panel switches to set the Interface ID number. In operation, it translates analog control inputs into digital commands and routes status information back to the keypad, enabling operators to monitor and adjust precipitator performance. As part of the RK2000 family, it works with the Interface Communications Cable and other peripherals to coordinate control of the system’s primary voltage and current limits and related secondary signals in electrostatic precipitator controls.
