Monitoring System 500T - Remote Site Monitoring Bundle

Didactum Monitoring System 500T - Remote Site Monitoring Bundle

The Didactum 500T Remote Site Monitoring is the ultimate SNMP monitoring system for data centers, server rooms, and critical infrastructures where every second of power loss can cost hundreds of thousands of euros.

This ready-to-use all-in-one package includes everything needed for fully reliable 24/7/365 protection: Didactum 500T, precision temperature sensor, humidity sensor, water sensor, smoke sensor, AC mains voltage sensor (power failure alarm), and built-in GSM modem SMS alarm module with external magnetic antenna.

Scope of Delivery – Everything Included for Immediate Use

  • Didactum Monitoring System 500T – 1U 19″ high-end appliance, ARM Cortex CPU, Linux 64-bit, 8 analog ports, 4 dry contacts, 2× CAN-Bus, HTTPS/TLS 1.3, SNMP v3 AES-256
  • Temperature Sensor – calibrated ±0.3 °C, -40 to +100 °C, range up to 100 m, 2 m RJ11 cable + mounting set
  • Humidity Sensor – 0–100 % RH ±2 %, includes 2 m cable + screws
  • Water Sensor – detects just 2 drops, gold-plated contacts, extendable up to 100 m, includes 2 m RJ12 cable
  • Smoke Sensor – EN-54 photo-optical, connectable in series up to 15 units (150 m), 2 m cable
  • AC Mains Voltage Sensor – immediate alarm on power outage or fluctuations outside 180–260 V, 1.8 m USB–RJ12 cable
  • GSM Modem Module – quad-band, external 3 m SMA antenna with magnetic base (perfect reception even in steel racks), SIM card not included

When the Power Fails – You Know FIRST

The included AC mains voltage sensor simply plugs into a 230 V socket. As soon as voltage drops below 180 V or fails completely, the Didactum 500T triggers an alarm within 3 seconds – via SMS (even without Internet), e-mail, and SNMP trap to Nagios, PRTG, or Zabbix. Perfect for UPS monitoring, backup power supplies, and critical systems.

Why the Didactum 500T POWER Bundle is Germany’s Best-Selling Solution

No fans, no hard drives – only fanless high-reliability electronics housed in a solid 19″ metal chassis. The integrated thermal sensor protects the unit from overheating above 70 °C through automatic shutdown.

Technical Highlights – Unbeatable in This Price Class

  • 8 RJ11 ports + 2× CAN-Bus = connect up to 76 sensors per device
  • CAN-Bus range 305 meters over standard CAT6 cable
  • Data logger with 60,000 records – expandable via USB stick to more than 10 years of storage
  • Zoomable graphs + CSV/JSON/PDF export with company logo
  • Alarm map 2.0 with integrated floor plan editor (upload PDF/PNG)
  • PING monitoring of 100 IP addresses with packet loss chart
  • Supports MQTT, Modbus/TCP, RADIUS, LDAP, Active Directory

GSM Modem SMS Alarm – Operates Even During Total Outage

Sends SMS alerts within 8 seconds – even if Internet, LAN, and power are down. Supports up to 10 phone numbers and custom message macros: “Server Room 2: POWER FAILURE! UPS has 12 min remaining!” Remote control by SMS: “RELAY1 ON” switches on emergency fans – confirmation instantly sent back.

AC Mains Voltage Sensor – More Than Just a Power Failure Detector

Measures voltage in real time (180–260 V). Triggers an alarm in case of:

  • Total power outage
  • Undervoltage (brownout)
  • Overvoltage (surge)
  • Voltage fluctuations over ±10 %

Ideal for monitoring UPS input voltage, generator startup, or transformer station status.
