+24 V
KL4494 | Bus Terminal, 2-channel analog input + 2-channel analog output, voltage, ±10 V, 12 bit, single-ended
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 digitized 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.
