РВ4Б sequence controller

РВ4Б, sequence controller

Used in industry, construction, agriculture and various process applications to set and automatically monitor the number of loading and unloading cycles, or to count discrete events or objects.
Developed to set and automatically monitor the number of concrete mixer loading cycles.

• A simple, convenient way to set and check parameters
• Two control inputs, two control buttons and two outputs
• Powered from a DC or AC supply
• If the mains supply fails, all current values are stored in non-volatile memory and restored automatically when power returns
• Galvanic isolation between the supply inputs, the control inputs and the output contacts.
• Electromagnetic immunity on the control inputs
• DIN-rail mounting with front conductor entry via terminal blocks.
• In "run" mode the unit counts the voltage pulses arriving at the control input. After the last pulse of the count, the output contacts operate and the sequence controller returns to "ready" mode.
