The ActionI/Q model Q106 is a DIN rail mount, DC voltage or current input limit alarm with dual setpoints and two contact closure outputs. The field configurable input and alarm functions offer flexible setpoint capability. Input voltage spans from 10mV to 200V and input current spans from 1mA to 100mA can be field configured. Bipolar inputs are also accepted.
Thanks to Action Instruments TouchCAL Technology, the Q106 is configurable as a single or dual setpoint alarm, with HI or LO trips and failsafe or non-failsafe operation. Also included are adjustable deadbands (up to 100% of full scale input) for each setpoint, a 24VDC voltage source (isolated from line power) for transducer excitation, and a universal AC power supply which accepts any voltage between 85 and 265VAC.
Advances in microprocessor technology enable Action to simplify setpoint calibration. Using a push-button instead of potentiometers, improvements in calibration resolution and reliability are realized due to the elimination of the potentiometers’ mechanical variability.
For calibration, the user simply inputs the signal level of the desired trip, pressing the push-button to store it in non-volatile memory. The deadband, or hysteresis level, is entered next with another pushbutton press to store.
The Q106 is equipped with three front panel LEDs. The green LED is a dual function LED labeled IN. This LED indicates line power and input signal status. Active AC power is indicated by the illuminated LED. If this LED is off, check AC power and wiring connections. If the input signal is 7% above or below the configured input range the green LED will flash at 8Hz or 4Hz, respectively.
Two red LEDs indicate the relay state for each setpoint. An illuminated red LED indicates the tripped condition.
The Q106 is equipped with two SPDT (form C) relays, rated at 120VAC or 28VDC at 5 amperes. Each of these relays is independently controlled by the field configurable setpoint and deadband.
