1405738

The 1405738 is an interface used in conjunction with most types of sensors in order to obtain measurements. It can be identified as a junction block suitable for a variety of input types such as RTD (resistance temperature detector), thermocouple, voltage or current inputs. The block\'s main purpose is to convert the varying signal into a standard 0-10V or 4-20mA for further processing or integration with control systems.

The 1405738 offers flexibility by supporting various combinations of signal inputs, which is determined by the selection of a connection module. This vast range of options includes Pt100 and Pt1000 inputs, which are widely used resistors for various temperature related measurements. Other options are available for specific applications such as thermocouples, grounding clips or other terminals.

The main feature of the 1405738 is its universal compatibility with many type of sensor inputs. Besides just converting the input signals, the junction block also has a few extra features that can be helpful in certain application. A micro adjustment trim potentiometer is an option that can be used to fine tune the input voltage or current signal. This can be useful in condition where very small input variations need to be measured accurately.

Once the correct connection modules are selected and the input signals are connected, the 1405738 converts the various signals into a constantly varying output voltage or current. The standard outputs are typically regulated either as a 0-10V or 4-20mA signal. The 4-20mA signal is preferred in industrial applications for its better performance, which includes low noise and extended cabling possibilites. The 0-10V signal is more commonly seen in laboratory and data acquisition applications.

In addition to the 1405738\'s universal input capabilities and adjustable output signals, it also has the ability to be configured for two-point and three-point calibration. Two-point calibration is the connecting two known points, while three-point calibration is the connecting three points, which is useful for gaining maximum accuracy.

Along with all the features the 1405738 has to offer, its low cost and easy installation make it a popular choice for interface solutions. The combination of user adjustable output voltages, a robust metal housing, universal compatibility with sensor inputs and temperature range from -50°C to 80°C provide good value for the cost.
