The Temperature Transmitter IS 4700 converts the sensor signal on input to temperature linear standard signal 0/4 to 20 mA or 0 to 5/10 V.
Due to the easy selection of the input and output ranges, the new universal power supply and the ultra-small housing the Temperature Transmitter is suitable for flexible use. High reliability and Protective 3-Port-Separation are further characteristics that make the IS 4700 unrivaled.
The configuration of measurement range can be easily set within -100 to +600 °C by using DIP switch. Subsequent readjustment after range selection or measured range compensation can then be performed at the Zero/Span potentiometers on the front panel. Alternatively, the Temperature Transmitter is also available customer-specific adjusted.
The small housing with 12.5 mm width saves space in your switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly. For range setting a simple housing unblocking is installed which makes it possible to reach easily all control elements on the mounting rail.
The new universal power pack for 20 to 253 V AC/DC means the IS 4700 can be used anywhere in the world, with all mains power supplies. The unit’s high efficiency contributes significantly to reducing the unit’s own heat generation. This is reflected in extremely high reliability and long-term stability.
