UPC601-U

UPC601-U Features ¨ ¨ UNIVERSAL SENSOR INTERFACE FOR PC DATA ACQUISITION ¨ ¨ ¨ Direct Sensor Input To PC Accepts ANY COMBINATION of: Thermocouples, Thermistors, Strain Gages, LVDT’s, RTD’s Variable Reluctance, Pots, Differential, or SingleEnded DC Volts 14 Bit A/D Over 11 Gain Ranges Frequency Inputs, Analog Outputs 16 Bits of Digital I/O DESCRIPTION The Validyne UPC601-U is a Universal Sensor Interface card for IBM PC/XT/AT or compatible computer. The UPC601-U will accept up to 16 analog sensor inputs directly; NO EXTERNAL SIGNAL CONDITIONING IS REQUIRED. Thermocouples, RTDs, potentiometers, strain gages, LVDTs and variable reluctance pressure transducers, as well as low-level DC voltages, may be wired directly to the UPC601-U IN ANY MIX OR COMBINATION. All required excitation and linearization is provided by the UPC601-U. 14 bit A/D resolution and 11 stages of programmable gain amplification to allow accurate measurement from sensor signal sources. The analog conversion rate is programmable to 5,000, 10,000, or 20,000 channels per second. Analog Inputs Thermocouple types B,E,J,K,T,R, or S may be wired directly to the UPC601-U; accurate linearization (fourthorder polynomial) and reference junction compensation are provided. RTDs and thermistors may also be wired directly to the UPC601-U; a 4 Vdc, 1 mA source excitation is included. Linearization is provided for RTDs and Thermistors. The UPC601-U supplies precision 4 Vdc excitation capable of driving 120 Ohm strain gages...
