The 370+ models in the DSCA signal conditioner family accept millivolt, volt, milliamp, RTD, thermocouple, potentiometer, strain gage, DC LVDT, frequency, AC to True RMS and two-wire transmitter inputs. Voltage input conditioners accept signals from ±10mV to ±40V, and current input conditioners accept signals of 0 to 20mA. Accepted thermocouple types are J, K, T, E, R, S, B, and N. RTDs can be 2- or 3-wire; potentiometer inputs can range from 0-100 ohms to 0-10k ohms, and strain gage transducers can have a resistance range of 100 ohms through 10k ohms. The DC LVDT module provides excitation and accepts input ranges from ±1V to ±10V. Frequency input signals can be TTL or zero crossing. The two-wire transmitter module provides loop power and accepts a 4 to 20mA input signal. Isolated field-side current and voltage outputs also are available.

All DSCA modules have excellent stability over time and do not require recalibration. However, multi-turn potentiometers are accessible and provide non-interactive zero and span settings adjustable up to ±5% for situations requiring fine tuning.

Signal bandwidth is 3Hz for most models; the exceptions being 100Hz for current input and two-wire transmitter interface modules, and 3kHz for strain gage and DC LVDT modules. Output noise is as low as 250µVrms on the low bandwidth models.

The DSCA module measures 2.95" x 0.89" x 4.13" (75mm x 22.5mm x 105mm). The operating and storage temperature range is -40°C to +80°C, and relative humidity can be up to 95% noncondensing. All modules mount to the standard DIN EN 50022 35mm rail. They are C-UL-US listed and CE and ATEX compliant.
