Power indicator for transducer [TR-1DA]

•Feature and application
Power indicator for Pirani gauge transducer:TRP-10
No pressure conversion error occurs on indicator due to digital communication of pressure signal from transducer
Maximum 3 units of TRP-10 can be connected for real-time measurement. Monitoring from outside possible due to installment of 3-channeled analog output and RS-485
Six set-point output can be assigned freely to any of 3 transducers: for example, to each one of 3 transducers can be assigned 2 points respectively, or to 1 transducer 6 points.
Power voltage is flexible between 100 to 240VAC.
