We offer Universal Input Scanner, which can accept various process inputs such as Thermocouples/ RTD sensors. Each channel can be of different type and the type of input can be programmed through the front keypad. Thermocouple input is built in the case of temperature inputs from thermocouples/ RTD the scanner directly displays the temperature values. In the case of 4-20 mA inputs from transmitters, the measuring range can be programmed for each channel and the scanner displays the values in engineering units for respective channels


  • Thermocouples/ RTD sensors: 4-20 mA signals

  • Cold Junction Compensation

  • If the inputs are Universal type, the scanner can accept 16 Channels input and if the inputs are either TC or 4-20 mA, then the scanner can accept 32 channels

  • There is provision for 16 Relay Outputs

  • Optional RS485 Communication with MOD BUS Protocol Interface is available to connect the scanner to any PLC/ DCS/ SCADA

  • Dot Matrix/ Thermal Printer can be connected to the Scanner and periodic print outs can be obtained

·         The PTRh-LC is a low cost High Accurate Module for measurement of
 Temperature and Humidity in Furnace, Oven, Deep Frrezers and Laboratory items.

With Sleek outlook, the module can be fitted anywhere and with a pair of wire for Communication plut pair of wire for Power input we can get the information about the Temperature and Humidity.

·         Temperature sensor in a plastic casing made especially for indoor temperature measurement.

·         Temperature range -50 to +75°C; Humidity : 0 – 98%

·         0.1 °C resolution for Temperature ; 2 – 3 % for Rh

·         Accuracy ±0,5 °C from -10 to +85 °C, otherwise ±2 °C

·         Communication line RS485 - up to 32 devices can be connected on a single bus (even more when a repeater is used)

·         ModBus RTU protocols supported

·         6-12V DC power - low power requirements (typically 10 mA)

 PTRh-LC Module is a digital temperature sensor. It measures temperature within the range from -50°C to +75°C and Humidity with range of 0 – 98% and sends the measured through RS485. The PTRh-LC Module has a very low consumption and communicates via an RS485 bus line using the MODBUS protocol. These features enable connecting more sensors with a four-wire bus line containing an RS485 link and supply cable to the distance of up to 1200m
