Sensor 0-20mA 1W-UNI: Measuring current 0 to 20mA

Electrically isolated 0 to 20 mA DC current measurement, 1-Wire UNI (RJ11) output.
Connect an external industrial probe with a 0-20mA output (“source” type). For example, the output of a current transformer.

Signal converter – sensor to measure 0-20 mA from an external current source. 1-Wire UNI bus (RJ11) output. The current input is electrically isolated from the 1Wire-UNI bus.

Measure the output current of any external industrial sensor that sources 0-20 mA (“source” type). For example, the output current of a current transformer.

Almost any industrial sensor can be connected to Poseidon2 or Ares units in this way. The values can be shared over LAN or GSM. When the current is out of a specified range, e-mail or SMS is sent. Can be connected to remote monitoring systems that are based on SNMP or Modbus/TCP.

  • The 0-20mA input is electrically isolated from the 1-Wire UNI bus (RJ11).
  • The sensor can be used in industrial environments.
  • Sensors can be daisy-chained (two RJ11 connectors).
  • Powered from the 1-Wire UNI bus (RJ11) or from an external power adapter.
  • Output reading in [mA] can be calibrated and/or converted to other units directly in the sensor.

Applications

  • Connecting industrial sensors to Poseidon or Ares systems
  • Connecting current transformers
  • Connecting electronic scales
  • Measuring the concentration of CO2 or other gases
  • Connecting pressure transducers or other industrial sensors

Connecting 0-20mA sensors to a LAN – remote monitoring (Modbus/TCP, SNMP)

  • Current transformer measures the passing current and converts it to 0-20mA at its output.
  • The "Sensor 0-20mA 1W-UNI" sensor – signal converter measures the current, its input is electrically isolated from the 0 to 20 mA input.
  • The "Sensor 0-20mA 1W-UNI" is connected to a Poseidon2 3266 remote monitoring LAN unit over the 1-Wire UNI (RJ11) bus.
  • The "Sensor 0-20mA 1W-UNI" is powered over the 1-Wire UNI bus (RJ11) from the Poseidon2 3266 unit.
     
  • Poseidon2 3266 displays the external voltage readings in its web interface.
  • Poseidon2 3266 sends an e-mail or a text message (SMS) when the voltage is outside of a specified "SafeRange".
  • Poseidon2 3266 shares data over the LAN using SNMP, XML (http) and Modbus/TCP.
  • Poseidon2 3266 can be connected to the SensDesk.com online portal.
  • Sensor readings can be displayed using an Android or iOS (Apple) app for tablets or mobile phones.

GSM monitoring of 0-20mA sensors (GPRS data, online portal)

  • Current transformer measures the passing current and converts it to 0-20mA at its output.
  • The "Sensor 0-20mA 1W-UNI" sensor – signal converter measures the current, its input is electrically isolated from the 0 to 20 mA input.
  • The "Sensor 0-20mA 1W-UNI" is connected to an Ares 12 remote monitoring GSM unit over the 1-Wire UNI (RJ11) bus.
  • The "Sensor 0-20mA 1W-UNI" is powered over the 1-Wire UNI bus (RJ11). The internal Ares battery provides back-up power.
     
  • Ares 12 is a GSM/GPRS unit for remote measurement and monitoring.
  • The current sensing "Sensor 0-20mA 1W-UNI" can be configured to convert units.
