This signal conditioner provides the galvanic isolation between field circuits and control circuits. This device is a standstill monitor that accepts input frequency pulses and triggers an output when the frequency drops below a preselected limit value. Two start-up override values are available. This unit can also be used to determine rotation direction. During an error condition or a power loss, the relay reverts to its de-energized state and the LEDs indicate the fault according to NAMUR NE 44. A line fault is not indicated. The device has LED status indicators for direction of rotation detection, limit detection, supply, and hardware faults. The device is easily configured by the use of DIP switches.
