KL3458
The KL3458 from Beckhoff offers eight analog inputs and an internal resistance of less than 85 Ohms. Part of the KL Analog Input Modules, it operates with a 4 to 20 mA current signal, provides 12-bit resolution, and completes conversions in ~4 ms.
It features 500 V electrical isolation, IP20 protection, and conforms to EN 60068 vibration and shock standards. It draws 105 mA from the K-bus and resists surge voltages up to 30 V DC.
