Features of
SQM5x.xxxxxZx
Actuators
SQM5xx.xxxxxZx 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.
