SQM5xx.xxxxxZx actuators contain the AGA56.9A... multi function circuit board. This
circuit board provides the following features:
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)
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.
