Key Features

• Remote switching of 4 relay outputs
• 8 signal inputs allow query of NO/NC devices
• Connector for plug-and-play sensors
• Fast and easy mounting on DIN rail
• NTP function can be activated
• Special High-Inrush relays prevent sticking of relay contacts during witch on pulse peaks

Switching functions

• 4 switchable, potential-free relay outputs with changeover connector (NO and NC)
• Each power port can be switched via HTTP(S), SNMP, ModbusTCP or command line interface via Telnet, SSH, MQTT and serial interface
• Switching voltage 230 V AC, 16 A / 24 V DC, 10 A
• Automatic switching of relay outputs depending on sensor thresholds or inputs possible
• Simultaneous switching of several switching outputs is prevented by automatic latency of 1 second
• Relays have high contact reliability even with very small loads
• States of inputs/outputs are indicated by two-color LEDs on the front panel
• Self-healing function thanks to 4-channel watchdog: Each power port can be assigned its own Watchdog (ICMP/TCP), which initiates an automatic restart if necessary

Security

• 1 connector for combined plug-and-play sensors (temperature, humidity and air pressure) to prevent often occurring physical hazards like overheating and increased humidity or air pressure
• Robust High-Inrush relays ensure safe switching operations
• 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

• Easy-to-read LED display for displaying total current, IP address and sensor values
• 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
