The ITP14 is a universally-applicable process display for monitoring and control of industrial processes. It has an analog input for voltage signals (0–10 V) or current signals (4–20 mA and others). It also has an NPN transistor output to control a load up to 42 V DC / 200 mA and to implement ON/OFF control. The potential groups (analog input, output, power supply) have galvanic isolation from each other.

The following video introduces:

• - Scope of delivery
• - Experimental setup with wire connection
• - Functions and Configuration
• - Simple operation and sample display of a temperature
• - Configuration of the alarm and activation of NPN transistor output
• - Settings of “safe output state”

In this video the ITP11’s functions and operation are introduced step by step.

Starting with the exterior design, going through the electrical installation until the configuration of:

• Password function
• Decimal point position
• 4 mA – lower limit (-999…9999)
• 20 mA – upper limit (-999…9999)
• Damping time
• Square root function
• Alarm function
• Lower setpoint limit
• Upper setpoint limit

Based on many requests, we have developed and released two new process indicators: ITP14 and ITP16.

The ITP14 is a universally-applicable process display with a voltage/current input, which can be set either for 0-10 V or 4-20 mA.

The ITP16 is temperature display, which supports many RTDs and a lot of different types of thermocouples.

All PLCs and mini-PLCs are very similar in terms of function, hardware, operation, design, etc., which makes them pretty interchangeable and universal devices. The most distinguishing aspect of such devices is programming software. That is why the user has to immerse themselves in learning the programming environment to program the device at hand. Sometimes, it is quite a time-consuming effort. To save your time, we decided to provide you with various sample projects on programming our programmable relay PR200. Our ultimate objective is to create as many such projects as needed to cover the whole functionality of programming environment akYtec ALP.

The RS485 interface has gained quite a common application in Fieldbus networks. This is a high-speed and interference-resistant serial interface which makes it possible to create networks connecting many devices into a common bus.

Due to circuitry optimization, the digital display ITP11 has been benefited from a significant improvement in the voltage drop. From now on it reaches 4 V max. Such a low voltage drop allows this process indicator to be powered from an active output of a PLC or other devices that the ITP11 is connected to. In addition, the ITP11 has got the alarm function. If this function is active and the process value is beyond the specified range, the screen starts blinking.

Interface is a shared boundary between two or more functional units (device, PC, etc.) defined by common physical interconnection characteristics, signal characteristics and functional characteristics of the interchange circuits.

Protocol is a standardized set of rules for data transmission over a communication interface.

Rigid cost restrictions and a huge variety of automation goals have led to the impossibility of creating a universal PLC. That’s why, even having selected a well suited controller, the developer may face the following challenges:

• - Lack of PLC resources, e.g. I/O-points, etc.
• - Issues with device compatibility with other devices in the network (interface, protocol, etc.)
• - Long distances between the PLC and field devices.

To solve these and other similar matters, remote I/O-Modules are intended. These modules are used in building distributed systems of control industrial objects and processes. They allow expanding these systems by more inputs or outputs of the same types or new types whenever the need arises, to provide more functionality of the system. Among many distributed systems the single-master systems based on serial interface RS485 and Modbus protocol have gained the highest prevalence rates in industrial automation. That’s why the I/O-modules from akYtec feature the corresponding interface and protocol.
