Jumo's ecoTRANS pH03 rail-mounted transmitter measures pH, redox, temperature and conductivity of ultra pure water. The measured values can be passed on to PLC as an industrial standard signal. The standard signal emissions are galvanically separated from the measuring input. The span can be freely programmed: pH between -2.00 and +16.00pH, redox between –150 and +1500mV and temperature between –10 and +150°C. The temperature display can be converted from °C to °F. The device can be set to a secure, pre-defined operating status via a binary input. In this way it can be defined which circumstances the outputs accept in HOLD mode: min. value, max. value, frozen status of last measuring value etc. This mode ensures a secure operating status. The JUMO ecoTRANS pH03 is provided for non-explosion proof applications and needs a supply voltage of 20…30V DC with a power input of < 3W. The electrical connection is maintained via screw clamps, which allow a wire diameter of 0.14…2.5mm. The carrying rail case with the dimensions 110mm x 22.5mm x 127.5mm (H x W x D) corresponds to protection type IP20.
