Controller module with LED light TX

Electronic units for the measure and control of various electro-chemical parameters, with RS485 serial interface and MODBUS RTU communication protocol. Programmable instruments that receive the input from different sensors for electro-chemical analysis and from pertinent temperature sensors. Configuration is easily operated through PC or PLC through the serial interface with a flexible software included in the supply. The electronic unit includes two 4-20 mA analog outputs (measure and temperature retransmission), two digital outputs from relay (alarms on measure and/or temperature). Two digital inputs are available for automatic remote calibration or for measure hold and external alarm acquistion. The instrument is suitable for rear panel mounting, DIN bar. It is also available in an IP65 houding suitable for outdoor installation.
