Control indicator R35.20

General information


Control indicator R35.20 is performed on high-speed single chip AD processor SIGMA-DELTA. It is intended for industrial weight batching systems. R35.20 supports multi-component batching (up to 8 ingredients), batching in accumulation mode, and data record of 10 formulas in memory. Controller has standard RS232 and RS485 communication ports that permit to connect to PC, PLC, DCS and other. It is equipped with 7-inch TFT display. R35 is applied in many branches of industry, such as: metallurgy, chemical industry, building material production, varnish-and-paint production, cereal and feed mixture production, bottling of drinks and etc.
