Optional Retransmit Output
Introduction
The SVi1000 supports a 4-20mA Position Retransmit Feedback option. The retransmit output
requires a DC power source (10V~30V) to properly function. The signal could be input into a
DCS/ PLC analog input module to read out the current valve position.
The output terminals are polarity sensitive and must be connected only to a DC circuit. The
Retransmit (+) terminal must be electrically positive with respect to the (–) terminal.
In normal working conditions, the retransmit output follows the valve position by outputting a
4- 2 0mA analog signal. If the positioner stops working due to lose of loop power or
malfunctioning, the retransmit output stays at around 3.2 mA.
This section discusses the necessary precautions when configuring a system.
CAUTION
An incorrect polarity connection will result in
device not properly functioning or with internal
circuitry damage.
CAUTION
Consult with qualified personnel to ensure that
electrical requirements for the switch are met.
The external series resistor is normally located in a DCS/PLC analog input module, so that the
valve position (current) can be transferred into voltage (Figure 35).
