Mighty Module Model DIS873
RTD Input Process Indicator
The DIS873 provides a display, optional isolated DC output voltage or current proportional to an RTD input signal, and optional alarm setpoints. The units include filtering and conditioning to reduce susceptibility to transients and noisy operations. The digital display utilizes an auto-zero dual-slope integrating A/D converter for accuracy and stability.
All controls are accessible by removing a gasketed front access panel. The display controls are wide ranging so that they can be calibrated to display engineering units. Decimal point selection is made with a switch, also accessible from the front. A complete set of engineering unit labels is sent with each DIS. Once the display has been adjusted to read the correct engineering units, the alarm setpoints can be adjusted without test equipment and without disturbing the output voltage or current.
Either setpoint may be displayed by use of the SP CAL switch. Each setpoint has an LED to indicate alarm status. The alarms have adjustable deadbands. Terminations are made to a screw terminal connector on the rear of the case.
Temperature indication, control, monitoring, data acquisition and warning for HVAC, pumps, motors, etc.
The DIS is designed to be mounted from the front of a panel through a standard horizontal 3.62 x 1.77 (1/8 DIN) cutout. Two mounting cam-screws secure the DIS to the panel.
* Within specified range limits.
** Compliance: The sum of the voltage drops in the output loop cannot exceed 24 V at rated current
