Tasks that formerly required multiple monitors can now be accomplished by using a single unit. Signals from 7 different transducers are carried into conveniently located screw terminals that are accessed through a sealed plastic cover. The unit automatically scans each channel, displaying the channel number and its process reading. Signals from thermocouples, RTDs, and thermistors are linearized and can be displayed in °C or °F. Current, voltage, and millivolt signals are easily scaled for indicating the process in specified engineering units. Up to 7 different processes can be displayed on a single scanner, and each channel can be assigned a 3-digit, alphanumeric engineering unit (psi, ft, etc.). Channels are sequentially displayed for a programmed length of time; with the hold feature, the display can be held indefinitely on any one channel. The DPS3300 has multiple display modes and can be programmed to scan all channels, display the channel with the highest or lowest reading, process deviation from a pre-programmed setpoint, and display differentials between channels. The DPS3300 can also run merely as a timer. Additional features include min/max readings and rate of change for all channels. A control relay or open-collector output for each channel is available as an option. A built-in buzzer (available with output option) sounds an alarm whenever a limit is reached. Visual indication of relay output status is given by LEDs. **M-117** **M** ## **Specifications** **Input Types:** J, K, T, E, R, S, B, Pt100 RTD and thermistor [2252 Ω @ 25°C (77°F)], 4 to 20 mA, 0 to 100 mV, 0 to 10 Vdc **Cold-Junction Compensation Error:** ±1°C max [10 to 40°C (50 to 104°F)] **Open Thermocouple Indication:** “HELP” displayed. **Custom Inputs Available:** Consult Engineering **Scan Rate:** Fixed—2 channels per second **Channel Interval:** Programmable from 1 to 999 seconds ## **Reliability/Accuracy:** **Calibration:** NIST traceable (temperature) **Resolution:** 1°C or F **Thermistor:** 0.1°C/0.2°F **Process:** 9999, 999.9, 99.99, 9.999 **Selectable Temperature Units:** Celsius or Fahrenheit **Analog-to-Digital Conversion:** 20,000 count A/D converter; dual-slope integrating converter ## **Conversion Rate:** 7 conversions per second (typical) **Display:** Red 7-segment LED display, 7 digits, 20 mm (0.8") high; negative polarity indication **Over-Range Indication:** “HELP” **Display Test:** Briefly indicates 8.8.8.8.8.8.8 on power-up **Elapsed Time:** Displayed in hours, minutes and seconds **Format:** HH.MM.SS ## **Power Options:** 120 Vac—60 Hz (standard) 220 Vac—50/60 Hz (optional) 8 to 15 Vdc @ 900 mA (optional) ## **Relay/Open-Collector Output (Optional):** **Relays:** SPST, 1 A @ 28 Vdc or 0.5 A @ 120 Vac **Open Collector Output:** 50 mA max (internal 5 Vdc source) ## **Dimensions/Enclosure:** **Case:** 192 W x 160 H x 103 mm D (7.55 x 6.29 x 4.05") **Material:** Polystyrene with crystal-clear polycarbonate lid **Ingress Protection** : Up to IP65 (DIN standard) **Weight:** 1.4 kg (3 lb) **SM** |
