The DRA range are DIN Rail mounting 2 or 3 channel isolation amplifiers that can be configured during manufacture. Standard options are offered with 3 types of inputs, External Current Shunt, Internal Current Shunt and Internal Voltage Divider. It can also be offered as a customised unit with the input scaling and configuration defined by the user.
Isolation amplifiers provides a means to measure signals without the signal ground and measurement ground being directly connected. This is desirable in a number of instances in industrial applications:
The DRA isolation amplifiers have been designed to measure voltage or current. They have 3 channels that can be configured to measure anything from millivolts full scale up to ±1000V full scale. The signal may be voltage from an electrical supply, the phase of a motor, a solenoid drive, or it may be a voltage derived from a sensor such as a current sense resistor.
