Tree Tech offers the DM series of networked I/O modules to monitor and/or control auxiliary equipment, as well as the IT Series of analog signal conditioners and RR/RU rapid response relays for critical safety circuits.

 

 

Tree Tech DM Series Networked I/O Modules
The DM series of networked Data Acquisition and Control Modules interface to digital systems with any analog or electromechanical equipment that does not have a serial port and needs to be supervised or controlled. Three models are available, each one can be ordered with 8, 16, or 24 inputs/output points; the DM1 for the supervision of dry contact inputs, DM2 for the supervision of analog signal inputs, and the DM3 with output contacts for load switching.

Tree Tech IT Series Signal Conditioners
The Insulated Transducer (IT) is used in monitoring and protection systems for power transformers and reactors. Its function is to convert analog signals from temperature sensors (RTD), position of taps (potentiometric rings of on-lap tap changers), or current loop (signals in mA) into output values proportional to the input values. In the case of a RTD input, the IT performs the linearization of the sensor curve to obtain increased accuracy. Details >
