Key Features

• Integrated temperature, humidity or air pressure sensor
• 2 ports for addtional plug-and-play sensors
• Remote switching of relay output
• Signal input allows query of NO/NC devices
• Fast and easy mounting, also on DIN rail
• NTP function can be activated
• Robust and compact sheet steel housing
• Power supply also via Power-over-Ethernet (PoE) possible

Switching functions

• 1 switchable, potential-free relay output with changeover contact connection (NO and NC)
• High switching capacity 36 V, 3 A
• Switching if relay outputs possible depending on sensor thresholds or inputs
• Relay has high contact reliability even with very small loads
• Self-healing function thanks to 1-channel watchdog: Each power port can be assigned its own Watchdog (ICMP/TCP), which initiates an automatic restart if necessary

Security

• 2 connectors for combined plug-&-play sensors (temperature, humidity and air pressure) to prevent frequently occurring physical hazards such as overheating and increased humidity or air pressure
• Seperate passive signal input for polling NO/NC devices (e.g. smoke detectors, leakage sensor, door contact)
• 2 inputs for redundant power supply (12 V DC) via two external plug-in power supplies
• Additional power supply via Power-over-Ethernet (PoE) possible
• Generation of status messages and alarms (e-mail, syslog, SNMP traps MQTT, SSH, Telnet)
• Encrypted e-mails (SSL, STARTTLS)
• Access protection by IP access control
• Encrypted communication through SSL (TLS 1.1, 1.2, 1.3) and SSH
• Password protected access

Operation

• Firmware update via Ethernet during operation (no restart required)
• Simple and flexible configuration via web browser, Windows or Linux program
• Dynamic assignment of an IP address via DHCP or manual assignment of static IP address
• Rapid commissioning thanks to free and reliable drivers from our technology partners
• Mounting on DIN rail thanks to mounting clip
• Robust sheet steel housing with versatile mounting options
