Principle of operation
The DC 0 ... 10 V control signal (at terminals 3 and 4) is electrically isolatedin a high impedance input-differential amplifier, and converted into a pro-portional phase-cut signal of DC 0 … 20 V. The supply voltage areregulated by the electronic circuit, thereby extending the service life of thevalve.A DC 0 … 20 V phase cut signal can be connected to the slave input(terminals 5 and 6). This input signal is electrically isolated with an AC opto-isolator and trasmitted to the output stage without amplification orattenuation. When operating in this mode, the UA9 must be from the samesupply as the supply to the master signal controller (device).
The signal at output "C-" can be used for an override circuit.
Electrical protection
The control inputs are proof against interference voltages up toAC / DC 50 V.
The phase cut output signal is sustained short circuit proof(max. 5 A for 1 ms per mains cycle).
A PTC resistor (3 A) protects output "C-" (terminal 7) against short circuits.
Important notes:
The transformer power must beappropriate for the valve load(approx. 1.5 times the magnet power).
