When replacing temperature controllers, what concerns on-site personnel is "ease of replacement" and "ease of use."
When selecting a temperature controller, simply having many functions is not enough. It's also important that it fits into existing control panels, is easy for operators to read, and is easy to set up and maintain.
What can be solved with LT23B
Easy to upgrade from LT23A
The LT23B is a compact 48 x 48 mm controller designed with compatibility with the previous model, the LT23A, in mind. terminal arrangement is also the same as the LT23A, configuration easy to replace existing equipment.
Furthermore, the use of loader software allows for the transfer of settings from the LT23A. This enables the updating and enhancement of temperature controller functionality while utilizing existing control panels.
Easy to see and operation on-site.
The measured PV is 15.4mm with a high-brightness white display. Despite its 48mm square size, it is designed to ensure easy visibility in the field.
display level of the settings items can be selected from multi-function settings, standard settings, and simple settings. Furthermore, assigning frequently used functions to the FUNC key improves operation in the field.
Streamline configuration and maintenance through PLC/PC integration.
The RS-485-enabled specifications supports PLC link communication. This allows you to write PLC internal data to the LT23B and write LT23B data to the PLC.
Using dedicated loader software, you can read and write parameter and control status from your PC. This streamlines the setup and maintenance of multiple units.
Despite its compact size, it is equipped with features that are easy to use on site.
High performance type PID
This system helps to quickly resolve hunting (fishing) and shorten the time required for settling down.
50ms sampling
You can select the input sampling period from 50, 100, 300, and 500 ms.
2 system control output
With option, heating/cooling control is also available.
Abundant measurement inputs
It supports thermocouples, resistance thermometer, and DC voltage / current.
Event Output
It handles alarms, heater disconnection, current, heater short circuits, and more.
Front IP66
It provides front protection when the board is installed.
Let's also check the points to note regarding the LT23B.
The LT23B is a temperature controller that is easy to use for on-site replacements, but prior confirmation is necessary depending on the application.
1. Ethernet-based communication is not directly supported.
The system is configuration for communication using RS-485, Modbus, and PLC link communication. If Ethernet or cloud connectivity is required, please check configuration including the PLC and communication converter.
2. A dedicated loader cable is required for PC setup.
If you are using the loader software, a dedicated USB loader cable is required. For deployments involving multiple units or for maintenance purposes, it's advisable to have one prepared as well.
3. Input specifications require model selection.
Thermocouples, resistance thermometer, and DC voltage / current are selected according to their intended use. For replacement of existing equipment or spare parts management, it is important to check the current input specifications.
I'm casually in a situation like this.
Replacing existing LT23A
This is suitable for facilities that want to replace their temperature controllers while minimizing panel modifications and wiring changes.
small heating device
High-performance PID and 50ms sampling help stabilize temperature control.
Packaging machine/molding machine
It can be used for multi-zone temperature management, such as heater control and seal temperature control.
Testing equipment and evaluation equipment
Setup and adjustment tasks can be streamlined by configuring and monitoring from a PC.
heating/cooling control
option The two regulated outputs of the control allow for a combination of heating and cooling.
Small to medium-sized devices that integrate with PLCs
With RS-485 specifications, it supports PLC link communication and is configuration for easy integration into equipment control panels.
