Features of
SQM5x.xxxxxZx
Actuators
SQM5xx.xxxxx
Z
x actuators contain the AGA56.9A… multi function circuit board. This
circuit board provides the following features:
Multiple Input Signals
The AGA56.9A… circuit board accepts the following input signals:
Line voltage
•
Power to A drives the actuator open to the setting of switch cam I (Maximum).
•
Power to ZL drives the actuator closed to the setting of switch cam III (Minimum).
•
Power to Z drives the actuator closed to the setting of switch cam II (Economy).
•
4 to 20 mA
(Signal to Y3, common to M)
•
0 to 135
Ω
(Slide wire signal to Y0, potentiometer connected to M and U4)
•
0 to 10 Vdc
(Signal to Y1, common to M)
•
0 to 20 mA
(Signal to Y2, common to M)
Multiple Output Signals
The AGA56.9A… circuit board provides the following output signals:
•
4 to 20 mA
(Signal from U3, common to M)
•
0 to 10Vdc
(Signal from U1, common to M)
•
0 to 20mA
(Signal from U2, common to M)
Double potentiometers ASZ22… provide additional output signals.
