Sensorex EM805-EC Smart Conductivity Modules (4-20mA or MODBUS/RS485) for S8000 Series

Overview

MODBUS/RS485 Interface for conductivity sensors The EM805-EC is our most cost-effective solution for connecting our S8000 series Contacting Conductivity sensors to a PLC or SCADA system. This small electronic module functions as a blind transmitter with a 4-20mA or MODBUS/RS485 output. No additional instrumentation is required to condition the sensor signal to be read by your PLC or SCADA. It can also be used to pair Sensorex sensors with any controller that has a 4-20mA or RS485 input card. Easily connects to our CS300 Modular Contacting Conductivity Sensor Cartridge and S856 cable to form a complete monitoring solution. Blind 4-20mA or MODBUS/RS485 transmitter for connecting conductivity sensors to PLC or SCADA Small form factor saves valuable panel space Input Voltage Options: 12V DC – MODBUS only 24V DC – 4-20mA & MODBUS Compatible with CS300 conductivity sensor Compatible with PT1000 RTD temperature compensation
