Article No. KL3404

KL3404 | Bus Terminal, 4-channel analog input, voltage, ±10 V, 12 bit, single-ended

The analog input terminal KL3404 processes signals in the range between -10 and +10 V. The voltage is digitised to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device. In the KL3404 Bus Terminal, the four inputs are 2-wire versions and have a common ground potential. The reference ground of the inputs is the internal ground. The LEDs indicate the data exchange with the Bus Coupler.
