Mighty Module Model DIS474
Thermocouple Input Process Indicator
The DIS474 displays temperature as measured by a thermocouple input. The unit includes 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.
A unique analog thermocouple circuit with digital linearity compensation provides the optimum combination of resolution and thermocouple linearization. Linearization is better than +/-1ºC from -200ºC (-328ºF) to the thermocouple's upper limit on all ranges. 0.1ºC/0.1ºF resolution is available for thermocouple types J, K, T, E and N (-199.9 to +199.9ºC/ºF). A temperature-sensing I.C. potted inside the input connector provides optimum cold-junction compensation.
All DIS instruments are gasketed and, when properly installed, are NEMA-4X splashproof and corrosion resistant. ZERO and SPAN controls are accessible by removing a gasketed front access panel.
A plug-in range card, accessible without opening the case, permits user recalibration for all thermocouple types and ranges. ºC orºF is selected using switches accessible from the rear. A rear-panel jumper selects upscale or downscale burnout indication.
A complete set of engineering unit labels is sent with each DIS. Terminations are made to a screw terminal connector on the rear of the case.
Temperature indication and monitoring.
The DIS is designed to be mounted from the front of a panel through a standard horizontal 3.62 x 1.77 inches (1/8 DIN) cutout. Two mounting cam-screws allow the securing of the DIS to the panel from the front.
