FAQS

• What is EA1*A ？
  EA1*A is a 2-wire Transmitter
• What is a two-wire transmitter?
  A 2-wire transmitter is loop-powered, which means it is powered by a low voltage, low current, DC power supply, typically 24V. A 4-20mA current is usually supplied by a distributed control system or other centralized data acquisition hardware and connected to the transmitter via 2 wires.
• What is the difference between a 2-wire and 4-wire transmitter?
  Where they can be applied, two-wire transmitters offer a straight forward solution for delivery of analog process measurement signals. A "four-wire" transmitter gets its name from, you guessed it, the two pairs of wires used to provide operating power and a signal transmission path.
• How does 2-wire work?
  In telecommunication, a two-wire circuit is characterized by supporting transmission in two directions simultaneously, as opposed to four-wire circuits, which have separate pairs for transmit and receive.
