Technical Data Humidity - Temperature Measuring System PCE-WMS 1 | |
Main unit remote maintenance module PCE-SM61 warehouse surveillance system | |
Input | RS 485 Modbus |
Output | 2 relays |
Interface |
Ethernet: configuration / communication USB: configuration |
Supply voltage | 20 ... 40 V AC / DC |
Power consumption | 4 VA |
Protection class | IP 40 |
In addition to the input for the PCE-P18-1 sensor units, the remote maintenance module also has relay outputs. These relays can switch on preset alarms. Furthermore, the remote maintenance module is read out and configured via the attached Ethernet interface. A special highlight of the main unit of the warehouse surveillance system is that this system can send alarms via email. This has the advantage that a preset user is informed directly by email if, for example, a measured value has been exceeded or if the memory is ready to be read out. | |
Main unit power supply PS24V03A | |
Input voltage | 90 ... 240 V AC |
Output voltage / current | 24 V DC / 3 A |
The power pack from the warehouse monitoring system supplies the remote maintenance module PCE-SM61 and the connected sensor units with voltage. The power supply, which is built into the main unit, enables up to 40 sensor units to be supplied. The remote maintenance module for warehouse monitoring and the power pack are delivered pre-wired in a wall-mounted housing. Installation is no longer necessary. Only the network configuration has to be done. The main unit of the warehouse surveillance system is ideally placed close to a network socket. From there, the PCE-WMS 1 is integrated into the LAN. The sensors are connected separately via the additional RJ45 socket. | |

The sensor unit measures temperature and humidity. In addition, other parameters for warehouse monitoring are output via the interface. The sensor unit is delivered ready for connection. Upon receipt, the sensor unit simply has to be connected to the main unit, the temperature and humidity meter, for the warehouse using a standard patch cable. The main unit recognizes this sensor immediately and the sensor unit only has to be added in the configuration. | |
The warehouse surveillance system sensor can be unobtrusively mounted at any point in the warehouse. The connection is made via the RJ45 cable socket. The sensor can be connected to the main unit via any network cable. | |
Visualization of the measurement data for warehouse monitoring in the administrator area | |
The system administrators can make all settings for the remote maintenance module in the administrator area. In addition to the display of the measured values on the map and in tabular form, alarms can be set here, users can be managed and storage settings can be made. Of course, it is also possible to integrate additional sensors and set up the map display. | |
Tabular representation of the data in the user area | |
The measured values can be viewed in the user area. Furthermore, the alarms can be viewed in the user area. The user area offers limited access compared to the administrator area. This prevents unauthorized personnel from changing or deleting settings on the warehouse surveillance system. Of course, the graphical view of the measured values is also possible, as shown in the example in the administrator area. | |
Download of the saved measurement values | |
The measured values stored by the warehouse monitoring system can be downloaded via an FTP program. You can then view the measured values in a database. |
