Easy Field Configurable Input Ranges

Two Adjustable Setpoints Programmable HI or       LO and Failsafe or Non- Failsafe

Flexible Power Supply Accepts 9 to 30VDC

24VDC Transducer Excitation

ASIC Technology for High Reliability

The ActionI/Q model Q108 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 Q108 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 DC power supply which accepts any voltage between 9 and 30VDC.

Touchcal Technology
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.
