KL4494 | 2-channel analog input, 2-channel analog output terminal -10…+10 V

The KL4494 Bus Terminal combines two analog inputs and two analog outputs in one housing and can process signals in the range between -10 to +10 V. The voltage is digitised to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device or to the process level. The input and output channels of the Bus Terminal have a common ground potential. The run LEDs give an indication of the data exchange with the Bus Coupler.
