Thermocouple Temperature converter and mV Isolated converter DAT4531A

General Description

The thermocouple temperature converter and mV converter DAT4531A is a din rail mount converter with internal or external cold junction compensation. It is programmable by PC or DIP Switches. The DAT4531A accepts signal from various Thermocouples (J, K, S, R, B, E, T, N) and mV up to 800mV. The DAT4531A converts this signal and makes the scale linearized. It also compensates for cold junction compensation. The DAT4531A provides Voltage or Current output.
