General Description

The DAT4235 is an all-way signal isolation converter with isolated input, output, and power supply. It is designed for DIN rail mounting and is PC programmable. With a thickness of only 12.5 mm (1/2 inch), it allows compact installation on either top hat DIN rail or G type DIN rail.

Key Features

  • Universal Input: Selectable from thermocouples, RTD, mA, V, mV, resistance, and potentiometer.
  • Bipolar Input: Can accept negative inputs such as -20mA or -10V.
  • Thermocouple Compatibility: Linearizes the input and provides a 4-20mA or voltage output signal.
  • High Accuracy: Accurate to 0.1% full scale with less than 0.01%/°F thermal drift.
  • PC Programmable: Programmable using Prosoft software version 3.06, developed by DATEXEL. The software is user-friendly and available for free download at www.datexel.com.
  • RTD and Resistance Sensors: Supports 2, 3, or 4 wire RTD configurations.
  • Configurable Ranges: Allows setting of minimum and maximum input and output values at any point of the scale, maintaining the minimum span shown in the datasheet. Selectable high or low burnout alarm.
  • Isolation: Provides 1500V isolation between input, output, and power supply, eliminating the effects of ground loops and allowing use in harsh industrial environments.
  • EMC Compliance: Compliant with the 89/336/CEE standard for Electromagnetic Compatibility.
  • Compact Design: Housed in a 12.5 mm thick plastic enclosure, suitable for DIN rail mounting per EN-50022 and EN-50035 standards.
  • Cold Junction Compensation: Measures and linearizes standard thermocouples with internal cold junction compensation.
  • Special Version - DAT4235SEL: This version allows the output signal to be enabled and disabled when a voltage is applied to the SEL terminals. The output is disabled and goes to a high impedance when the SEL input is energized by 4 to 30 VDC, enabling the use of several DAT4235SEL units as a multiplexer.
