image of DIN rail mounting Amplifier type DR7DC

The DR7 is a DIN rail mounting amplifier designed to install in suitable cabinets along with other similar devices.
To reduce electrical noise, system problems and the risk of accidental damage the DR7 has full isolation between supply and output.
A wide supply voltage tolerance and selectable excitation ensure that the DR7 is compatible with a very wide selection of transducers and applications.
