Features

N/A The Model SCD1 is a series of signal conditioners which provide bridge excitation, amplification, span and balance controls and a choice of ±10 Vdc and/or 4-20 ma outputs. Primary input power is available in 120 Vac or a variety of Vdc voltage levels.

The SCD1 can accommodate up to four channels with ±10 Vdc outputs or a maximum of 2 channels with 4-20 ma outputs.

Standard SCD1 models are packaged in a NEMA-12 rated cabinet (NEMA-4X packages are available).

Each input channel is connected via a six (6) pin receptacle (PT02A-10-6S)

All output signals are provided at a terminal strip inside the signal conditioner cabinet . Each output signal has an individual terminal connection and each signal shares a single common return.

Note: When ordering specify input sensitivity, and desired full scale output.
