The Digital Pressure Transducer (T5400) assures compatibility with most digital input systems. It maintains set points under adverse vibration conditions. This product allows installation flexibility for most applications and facilitates ease of calibration. It also provides stable operation over wide operating temperature range and output which is directly or inversely proportional to the input signal. The function will return the output to 3 psig for direct acting mode or to 15 psig for reverse acting mode if the power is lost, regardless of the logic selected. The Fairchild T5400 Fail Safe High or Low will return the output to 3 psig for Direct Acting Mode or to 15 psig for Reverse Acting Mode if the power is lost, regardless of the logic selected.
