2.1 Introduction
Fig.1: KL4494
Analog terminal with two input and two output channels, -10 V to 10 V
The KL4494 Bus Terminal combines two analog inputs and two analog outputs in one housing and can
process signals in the range -10 V to +10 V. The voltage is digitized to a resolution of 12bits, 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 that is electrically isolated from the
0V power contact. The RUN LEDs give an indication of the data exchange with the Bus Coupler.

2.4 Basic function principles
Analog input channels
The analog input channels of the KL4494 process signals in the range from -10V to +10V with 12-bit
resolution (4095 steps). The inputs are single-ended inputs with a common ground potential.
Format of the input values
In the delivery state the process data are shown in two's complement form ( -1integer corresponds to 0xFFFF).
Siemens output format [}34] can be selected via the feature register R32 as an alternative.

Process data equations
The process data that are transferred to the Bus Coupler are calculated using the following equations:
Product overview
KL4494 9Version: 2.0.0
Neither user nor manufacturer scaling is active
Ya = (Ba + XADC) x Aa(1.0)
Yout = Ya
Manufacturer scaling active (default setting)
Y1 = Bh + Ah x Ya(1.1)
Yout = Y1
User scaling active
Y2 = Bw + Aw x Ya(1.2)
Yout = Y2
Manufacturer and user scaling active
Y1= Bh + Ah x Ya(1.3)
Y2 = Bw + Aw x Y1(1.4)
Yout = Y2
Key
Xadc: Output values of the A/D converter
Yout: Process data to PLC
Ba , Aa: Manufacturer gain and offset compensation (R17 [}33], R18 [}33])
Bh , Ah: Manufacturer scaling (Not implemented)
Bw, Aw: User scaling (R33 [}34], R34 [}35])
The equations of the straight line are activated via register R32.
Analog output channels
The analog output channels of the KL4494 generate signals in the range from -10V to +10V with a
resolution of 12 bits (4095 steps). The outputs are single-ended outputs with a common ground potential.
Format of the output values
In the delivery state the process data are shown in two's complement form ( -1integer corresponds to 0xFFFF).
Siemens output format [}34] can be selected via the feature register R32 as an alternative.

Process data equations
The process data, which are transferred to the Bus Terminal, are calculated based on the following
equations:
Neither user nor manufacturer scaling is active
Ydac = XxAa+Ba(1.0)

Manufacturer scaling active (default setting)
Y1 = Bh + Ah x X (1.1)
Ydac = Y1xAa+Ba
User scaling active

Ydac = Y2xAa+Ba
Manufacturer and user scaling active
Y1= Bh + Ah x X (1.3)
Y2 = Bw + Aw x Y1(1.4)
Ydac = Y2xAa+Ba

X: Controller process data
Ydac: Process data to D/A converter
Ba , Aa: Manufacturer gain and offset compensation (R19 [}33], R20 [}33])
Bh , Ah: Manufacturer scaling (Not implemented)
Bw, Aw: User scaling (R36 [}35], R37 [}35])
The equations of the straight line are activated via register R32.
