Station
*1 Power-saving mode. The display will remain OFF at all times with the default setting. (Turns ON with button operation); Network communications with host devices cannot be made.
* 2 This mode establishes a one-to-one network connection with the Air Particle Sensor (model ZN-PD□□-S□), and simultaneously logs particle count values and temperature/humidity data to the SD card. Network communications with host devices cannot be established.
* 3 Automatically writes data to the SD card upon reaching the upper limit of the internal memory, and continues recording up to the upper capacity limit of the SD card. If no SD card is inserted when the upper limit of the internal memory is reached, recording will stop. (Data can be output to the SD card by pressing the button after inserting the SD card.)
*4 This mode always records the latest measured values for the upper limit of the internal memory. (When the upper limit of the internal memory is exceeded, data items will be deleted beginning with the oldest data item)
*5 An alarm is output upon exceeding the upper limit value or lower limit value set in the threshold setting mode.
*6 A connection guide book is available for connecting to OMRON PLCs.
* 7 Not including the air particle sensor connection mode.
* 8 If using an SD card from another manufacturer (compatible with SD/SDHC card standards), data integrity cannot be guaranteed, as, depending on the SD card, there may be cases in which the card is temporarily able to read and write data, but cannot be recognized correctly during use. Please use the recommended SD cards with this product.
* 9 Nickel‑metal‑hydride batteries and alkaline batteries can be used. Manganese batteries cannot be used.
* 10 Battery life may vary depending on the measurement environment, sampling and battery type/performance.
* 11 The included connector is XW4B-02B1-H1 model, manufactured by OMRON Corporation.
Main Product Features
Unparalleled measurement accuracy
Offers a temperature resolution of 0.1°C and humidity accuracy of ±2.5%.
This allows for more precise control of temperature and humidity, contributing to improved product quality.
Equipped with a hybrid logging engine
Data can be logged to the unit (SD Card) while communicating with host devices via LAN.
Even in the event of a network failure, the unit will continue to record data.
Also enables centralized control by production technology divisions via network, with local control via SD card on the manufacturing floor.
Enables immediate response when trouble occurs
Equipped with an alarm output.
Any abnormalities in temperature or humidity are made visibly detectable, enabling immediate response.
Facilitates easy systemization of production lines.
Temperature and humidity are essential data for quality control on the manufacturing floor.
Keep temperature and humidity changes visible at all times at multiple points.
Backup using two commercially-available AAA batteries, even during a sudden power failure
Equipped with a battery‑backup function to provide non-stop LAN communication and logging operations, even in the event of a power outage or interruption.
- *In network mode, operations can continue for approximately 2 hours on batteries alone. However, battery life may vary depending on the measuring environment and battery type/performance.
Bundled with simple, user-friendly PC software
Simple, user-friendly PC software is available as a standard feature (Station Utility: Setup tool, logging tool and SD Viewer ES). Main unit setup and data logging can be done via LAN network. Additionally, logged data can be easily displayed in a waveform graph.
