KL3204-0018 by Beckhoff

The KL3204-0018 module from Beckhoff's KL Analog Input Modules delivers precise analog temperature measurement. It offers four inputs, a resolution of 0.1 degC per digit, a 2-wire connection, and a conversion time of roughly 250 ms. Designed for industrial accuracy, it achieves a measurement error of less than +/-1 degC and operates with a typical 0.5 mA measuring current. Weighing nearly 70 g, it also provides 500 V electrical isolation.
