KL3182 | 2-channel analog input terminal -2…+2 V (accuracy 0.05 %)

The KL3182 analog input terminal processes signals in the range of -2 to +2 V. The voltage is digitised to a resolution of 16 bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the Bus Terminal have differential inputs and a common, internal ground potential. With the high measurement accuracy of ±0.05 % (relative to full scale value), the terminal is optimised for high-precision control processes, such as dosing, filling, or quality assurance. The Bus Terminal has two channels within a housing. LEDs indicate data exchange with the Bus Coupler.
