EM805 - Smart modules (4-20mA or MODBUS/RS485) for S8000 Series

The EM805 is our most cost-effective solution for connecting our S8000 series pH and ORP sensors to a PLC or SCADA system. This small electronic module functions as a blind transmitter with software selectable 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.

• • Blind 4-20mA or MODBUS/RS485 modules for connecting ORP sensors to PLC or SCADA
  • Small form factor saves valuable panel space
  • Input Voltage, Modbus units: 7-40V DC
  • Input Voltage, MA units: 24V DC
  • Requires an S8000 series pH or S8000 series ORP sensor cartidge (inline and submersion available)
  • Compatible with  EA899 and EA891 series – Sensor Cartridge Housings
  • Requires S856 cable
  • Compatible with PT1000 RTD temperature compensation
