• 4 to 20mA DC input
• Single mechanical relay output
• 4.5V DC from input loop power
• Hi/lo fail-safe option trips alarms above or below set-point

The 260A accepts a 4 to 20mA input signal and provides a dry contact relay output if the input exceeds a user-defined set-point limit. Power is received from the input loop.        

• 4 to 20mA DC input
• 4 to 20mA DC output
• 10-36V DC power
• 1500 AC peak isolation prevents ground loops
• Calibration is independent of the load to eliminate load compensation adjustments

The 340i accepts a process current input and provides an isolated 4 to 20mA process current output signal.

• 0 to 25.6KHz frequency input range
• DC voltage or DC current output
• DIN rail G or T mount

These transmitters accept periodic or pulse waveform signals such as those originating from tachometers, magnetic transducers, and turbine flow meters, and provide a proportional process current or voltage output signal.    

• 4-20mA DC input
• 4-20mA DC output
• 12 to 50V DC @ 20mA (loop-powered)
• 1500V AC peak isolation DC prevents ground loops

The 270i accepts a process current input and provides an isolated 4 to 20mA process current output signal. Power is received from the input signal current.

• J, K, T, E, R, S, B Thermocouple Input
• DC Voltage or DC Current Output

These models convert sensor inputs to proportional process current or voltage output signals. Excellent accuracy and stability ensure reliable measurements in harsh industrial environments.
