Operating modes
TAKT = Full wave switch principle
VAR = Phase angle principle
QTM = Half wave switch principle (Quick Takt Mode)
(only for types 1A)
Setpoint inputs
2 setpoint inputs (SELV, PELV), isolated from the system.
- Setpoint 1: analog setpoint input
Signal ranges:
0(4) - 20mA R
i
= approx. 250Ω
0(1) - 5V R
i
= approx. 44kΩ
0(2) - 10V R
i
= approx. 88kΩ
- Setpoint 2: optional bus interface, connection of higher level PC or
automation system
Control characteristic
Each controller (e.g. temperature controller), with an output signal in
the range of 0-20mA / 0-5V / 0-10V, can be adapted to the power
controller.
