CF 26 2 4/2001 Description The Model DCM 433 is a self-contained, AC powered sign al conditioner for bridge type instrumentation. It contains a precision instrumentation amplifier with isolated, filtered output and a highly regulated, low noise, adj ustable output bridge excitation source.
CF 26 3 4/2001 Specifications NOTE: Unless otherwise noted, specifications appl y after one hour wa rm up at 25°C ambient. Temperature coefficients apply between 0°C an d 55°C ambient. Isolation Input to Output 700 VDC 60pF Amplifier Gain Adjustment Range Input 4-20mA Output 5 mV to 50 mV Linearity ±0.
CF 26 4 4/2001 Getting Started with the DCM 433 1. Excitation Supply. If remote sensing is not used, connect +Sense to +Excitation, terminal 3 to 4, and co nnect -Sense to -Excitation, terminal 1 to 2. 2. Apply power to the DCM 433 and adjust the Excitation su pply.
CF 26 5 4/2001 Transducer Excitation The bridge excitation supply voltage is set by SWB-1 and pote n tiometer E. Set SWB-1 ON for a fixed 10 Volts. This will provide the best temperature stability. The sup ply can be adjusted between 5 and 10 Volts by setting SWB-1 OFF and adjusting potentiometer E.
