This device has an integrated temperature sensor and is perfect for a wide range of solutions and an easy to configure software. It also can send email alerts you'll be notified if the device goes outside the safe limits set by you.

P8610-POE is wall mountable and requires just a Ethernet with POE Switch (No Power supply required). Comes with free software for simple monitoring and datalogging or optional software if you have many P8610 monitoring back to one central sever.

Used extensively in monitoring cold rooms, warehouses, server rooms


This comes with a free configuration and monitoring software. We also offer an advanced monitoring software (DBS Monitor) that is installed in your PC and server and will offer graphical, as well as numerical data and its history. This software will also monitor up to 100 Titanium series of products and will display all data together. Please see Sensors and downloads section for more information.

Power Supply - Please Note:This product does not include a power supply. If you require a power supply please order the power supply from the Sensors and Accessories Tab.

PoE requirement: Your PoE system needs to be compatible.


How it works

Modes of Communication

Modbus TCP: Modbus TCP protocol enables to read measured values, set alarm limits, adjust the probe.
Telnet: -Port 9999 enables to set alarm limits (lower, upper limits, hysteresis for measured values and time delay), e-mail addresses, SNMP addresses, probe description, refresh of www pages (10s to 65535s), set storing interval to history (10s to 65535s), enable each communication channel. Capacity of the history memory is 100 sets of temperature, humidity, pressure + computed values. Password protection of this port is enabled. Automatic IP address assignment from DHCP server is also enabled.
WWW pages: User selectable design of www pages enabling to display curve of measurement history. User can design the look of www pages and temperature, humidity, pressure + computed values history.
SNMP: It is possible to read actual values and alarm limits. In case of alarm creation warning message (trap) is sent to addresses defined by the user (maximum three addresses).
SOAP: Online transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s.

Online transmitter enables to monitor measured values. In case of exceeding of adjusted limits warning message can be sent to specified addresses. There are the following options of alarm indication:

Alarm Indication Options

E-mail: In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses) or via e-mail to SMS message. Basic SMTP authentication is supported.
SNMP: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses).
WWW pages: In case of exceeding of adjusted temperature, humidity, pressure + computed value limits active alarm is displayed on www page.
syslog: Online transmitter enables to send text messages to selected syslog server after different events appear. E.g. after transmitter restart, alarm activation, communication error with SNTP, after firmware change, after alarm termination, after communication error with SOAP server.

Synchronizing of time and record to www table and measured values history is enabled by SNTP via Internet

Dimensions of the case (W x H x D): 88 x 126 x 39,5 mm
