RDP Electronics Ltd is launching the low-profile DR7AC carrier amplifier, designed to provide excitation and signal amplification for LVDTs and other inductive transducers. The DR7AC is compactly packaged for DIN rail mounting, which will benefit systems integrators and machine builders.

Derived from the established heritage of RDP's successful S7AC series, the new amplifier significantly reduces system engineering and earth loop problems thanks to full isolation between the DC supply side (9 to 36V) and the amplified output. Offering transducer excitation options of 1 or 3 volts RMS, at either 3kHz or 5kHz carrier signal excitation, there is a choice of a full range output of either 10 V or 4~20 mA from switched selectable input signal levels ranging from 20mV to 4V RMS.

The DR7AC amplifier enjoys excellent thermal stability, with a dynamic response which is flat from static to 250Hz, offers low noise levels and is fully compliant with all relevant electrical and EMC standards and regulations. As with all RDP products, it comes with full instructions and is backed by a highly regarded engineering hotline support service (telephone number +44 (0)1902 457512).
