Basic function principles
The KL403x analog output terminals generate signals in the range -10 V to +10 V with a resolution of 12 bits
(4095 steps). The output voltage is electrically isolated from the K-Bus.
The LEDs indicate the operating state of the associated terminal channels.
• green Run LED:
◦ On: Normal operation
◦ Off: Watchdog timer overflow has occurred. If no process data are transmitted by the Bus Coupler
for 100 ms, the green LEDs go out. The output assumes a user-specified voltage (see
).
Process data input format
In the delivery state the process data are shown in two's complement form (integer -1 corresponds to
0xFFFF). Alternative presentation types can be selected via the feature register (

Process data
The process data arriving from the Bus Coupler are output to the process:
Y_dac = X
(1.0)
Neither user nor manufacturer scaling is active.
Y_1 = B_h + A_h * X
Y_dac = Y_1
(1.1)
Manufacturer scaling active
Y_2 = B_w + A_w * X
Y_dac = Y_2
(1.2)
User scaling active
Y_1 = B_h + A_h * X
Y_dac = B_w + A_w * Y_1
