Core functional features
1. High precision measurement and high-speed response
The module has excellent measurement accuracy, with thermocouple/platinum resistance (PT) input accuracy of ± 0.1% of the measured value (PV) and analog input accuracy of ± 0.1% of the full range (FS), ensuring the accuracy of parameter measurement. Simultaneously adopting a high-speed sampling period design with a sampling frequency as low as 60ms, it can quickly capture changes in on-site parameters, adjust control strategies in a timely manner, and avoid control deviations caused by response delays. It is suitable for precision control scenarios that are sensitive to parameter fluctuations.
2. Universal sensor input design
All models support universal input functions and are compatible with thermocouples, platinum resistors (PT), and analog signals (current/voltage). They can adapt to different types of field sensors without the need to replace modules, greatly improving the universality and application flexibility of the product, reducing the difficulty of system selection and spare parts inventory costs, and easily meeting diverse industrial parameter measurement needs.
3. Flexible output control and logical operation capability
The module is equipped with two sets of auxiliary output channels, supporting various forms of output such as relay output, voltage output (used to drive solid-state relays SSR), current output, and linear voltage output, which can accurately drive on-site actuators. Through the supporting software (CX Thermo Ver. 4.0), the output signal can be subjected to "AND/OR" logical operations and delay settings to meet the linkage requirements in complex control scenarios.
4. Rich status monitoring and alarm functions
Equipped with PV/SV status automatic switching display function, it can automatically switch display between measured value (PV), set value (SV) and controller operating status (automatic/manual, running/stop, alarm information), intuitively presenting the equipment operating status. At the same time, it integrates multiple alarm functions, including heater burnout alarm, solid-state relay (SSR) fault alarm, heater overcurrent alarm, and PV change rate alarm, which can timely detect equipment abnormalities and trigger warnings to ensure the safe operation of the system.
5. Preventive maintenance and communication expansion capability
Built in control output on/off counter, which can count the running times of relays in the temperature controller, providing data support for preventive maintenance of equipment and extending its service life. Some models support RS-485 or RS-232C communication interfaces for easy access to industrial communication networks, enabling remote monitoring and centralized management.

Applicable system and configuration requirements
The YOKOGAWA NP53 * C precision control module can be integrated into industrial automation systems as an independent control unit, or linked with PLC and DCS systems through communication interfaces. When configuring, the following points should be noted:
-Software configuration: The matching CX Thermo Ver.4.0 software is required to perform logical operations, set delay parameters, and communication parameters to ensure that the parameter configuration matches the control requirements
