KL3208-0010 | HD Bus Terminal, 8-channel input terminal PT1000, Ni1000 (RTD)

The KL3208-0010 analog input terminal enables connection of eight resistance sensors. The Bus Terminal’s circuitry can handle sensors using the 2-wire technique. Linearisation over the full temperature range is realised with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminal’s standard settings are: resolution 0.01 °C within the temperature range of Ni1000 sensors. The error LEDs indicate sensor faults (e.g. a broken wire).

The HD Bus Terminals (High Density) with increased packing density feature 16 connection points in the housing of a 12 mm terminal block.
