1 Overview ITP16 is a universally applicable process indicator and can be used with various input signals: RTD, TC, linear voltage signal. The device requires 24V DC auxiliary voltage. It is designed for control and monitoring of industrial processes. 2 Specifications ITP14 can be ordered in two versions. They differ in the display color. Ordering key: Table 2.1 Technical data Power supply Power consumption, max. Input Input signal Sampling time, max.

Example 2: di.Lo: -999 -> 4 mA di.Hi: 9999 -> 20 mA For the input current of 20.8 mA the correct indication should be “10548”. Actually “0548” will be displayed. Fig. 7.1 Device menu 8 Maintenance The maintenance includes: – – – cleaning the housing and the terminals from dust, dirt and debris checking the fastening of the device checking the wiring (connecting leads, fastenings, mechanical damage) The device should be cleaned with a damp cloth only.
9 Transportation and storage Pack the device in such a way as to protect it reliably against impact for storage and transportation. The original packaging provides optimum protection. If the device is not taken immediately after delivery into operation, it must be carefully stored at a protected location. The device should not be stored in an atmosphere with chemically active substances. Permitted storage temperature: -25…+55 °C ► NOTICE The device may have been damaged during transportation.
