The DRG Series signal conditioner modules accept a wide variety of input signals such as thermocouples, RTDs, strain gages, DC voltages/currents, AC voltages/currents, frequency and potentiometers and produce a proportional conditioned process output. The inputs and outputs are both field configurable and offer flexible wide ranging capability. The slim housing mounts on a DIN rail and is ideal for high density installation. All modules provide 1800 Vdc isolation between the input, output and power supply. One advantage of the DRG series is the field configurable input and output ranges. Each module can be set to a number of ranges by dip switch selection. Wide ranging precision zero and span potentiometers provide even further adjustment. The signal conditioners may be set for an almost limitless number of ranges. Range adjustment requires the use of a calibrator or reference source.

DRG-SC-TC Thermocouple Signal Conditioner
The DRG-SC-TC is a DIN rail mount thermocoupleinput signal conditioner. It can be field configured forover 60 different thermocouple temperature ranges.The output is linear to temperature and can be set foreither 0-5 V, 0-10 V, 0-1 mA, 0-20 mA or 4-20 mA. Zeroand span pots allow 50% adjustability of offset andspan turn down within each of the ranges. For examplethe 500-1000°C range could be offset and turned downto provide a 4-20 mA signal representing 750-1000°C.

The DRG-SC-DC DC Input Signal Conditioner
The DRG-SC-DC is a DIN rail mount DC voltage andcurrent input signal conditioning module. The inputcan be field configured for any one 12 voltage rangesfrom 10 mV to 100 V or 6 current ranges from 1 mA to100 mA. The output is linear to the input and can beset to either 0-5 V, 0-10 V, 0-1 mA, 0-20 mA or 4-20 mA for the DRG-SC-DC-U (unipolar outputs) and-5 V to +5 V or -10 V to +10 V for the DRG-SC-DC-B(bipolar outputs). Zero and span pots allow 50%adjustability of offset and span turn down within eachof the ranges. For example the 0-2 mA input rangecould be turned down to 0-1 mA and provide a fullscale output signal (e.g. 4-20 mA).
Voltages: 20 mV, 50 mV, 100 mV, 200 mV 500 mV,1 V, 2 V, 5 V, 10 V, 25 V, 50 V, 100 V
Current: 2 mA, 5 mA, 10 mA, 20 mA, 50 mA,100 mA

DRG-SC-BG Bridge/StrainGage Input SignalConditioner
The DRG-SC-BG is a DIN rail mount bridge or straingage input signal conditioning module. The fieldconfigurable input and output offers flexible, wideranging capability for bridge or strain gage applicationsfrom 0.5 mV/V to over 50 mv/V. Wide ranging,precision zero and span pots allow 50% adjustability ofoffset and gain within each of the 11 switch selectableinput ranges. The output can be set for either 0-5 V,0-10 V, 0-1 mA, 0-20 mA or 4-20 mA. This flexibility,combined with an adjustable (1 to 10 Vdc) bridgeexcitation source, provides the user a reliable,accurate instrument to isolate and condition virtuallyany bridge or strain gage input.
