SIG-5561 ezTCP Cloud-Enabled Ethernet Temperature Monitor

The SIG-5561 from Sollae Systems is an industrial-grade Ethernet temperature gateway designed for commercial and industrial environments. It connects to a , displays real-time temperature on its built-in LED, and streams data securely to the free  via MQTT over TLS for effortless remote monitoring vie a web interface and email notifications.

Applications

The Sollae Systems SIG-5561is ideal for commercial and industrial settings requiring precise, real-time monitoring over Ethernet for safety, compliance, and efficiency. It excels in harsh environments, enabling predictive maintenance, process control, and automated notifications without constant on-site checks.

Industrial Applications

• Manufacturing Processes: Monitor metal forging, plastic molding, semiconductor production, or chemical processing to ensure consistent quality and prevent defects from temperature deviations.
• Energy & Power Generation: Track boilers, turbines, transformers, motors, pumps, compressors, bearings, and gearboxes for overheating or friction issues, supporting predictive maintenance.
• HVAC & Machinery: Supervise motor windings, fans, blowers, and controlled environments in factories or warehouses to detect lubrication problems or airflow issues.
• Food Processing: Control ovens, freezers, and storage to maintain safety standards and prevent spoilage.

Commercial Applications

• Remote Site Monitoring: Ideal for monitoring conditions at remote sites such as remote transmitters, microwave relay sites, edge computing cabinets, pump and valve stations, remote signal & control cabinets, and distant outbuildings.  
• Food & Beverage Storage: Remotely monitor refrigerators, cold rooms, and warehouses for compliance with health regulations via email alerts for threshold breaches.
• Pharmaceuticals & Labs: Ensure precise temperatures in fermentation, sterilization, storage, fridges, and freezers to protect product efficacy.
• Healthcare Facilities: Track pharmacy refrigerators, hospital storage, and labs for vaccine or medication integrity.
• Building Management: Oversee indoor air quality, ambient room temperatures, or HVAC systems in offices, retail spaces, and data centers.

Why Choose SIG-5561? Built for Industrial & Commercial Reliability

• Rugged Design: Operates in -40°C to +85°C environments with surge/reverse voltage protection – perfect for factories, warehouses, HVAC systems, food storage, and harsh commercial sites.
• Precision Monitoring: ±0.3°C accuracy across -200°C to +850°C range (16-bit resolution), with 30-day data logging on the cloud.
• Secure & Scalable: TLS 1.2 mutual authentication, IPv4/IPv6 support, and multi-user cloud access for team monitoring.

Unmatched Ease of Use – Up & Running in Minutes

No complex wiring or software installs required. The SIG-5561 is plug-and-play simple:

1. Connect Hardware (2 minutes): Plug in DC 5V power, Ethernet cable (auto-sensing straight/cross-over), and 3-wire PT100 sensor to the terminal block.
2. Download spFinder Tool (free from Sollae site): Search and auto-login (default: sig-5561/sig-5561).
3. Network Setup (1 minute): Choose DHCP auto-IP or static – save and reboot.
4. Register on Sollae Cloud (2 minutes): Sign up free at Sollae Cloud, enter the device's Client ID from spFinder, and it's online.
5. Set Web and Email Alerts (1 minute): In the cloud dashboard, define high/low thresholds – get instant email notifications for out-of-range temps. Customize with widgets or link to relays such as the and for automated control based upon the temperature settings. 

Total Setup: Under 10 minutes. Monitor via any web browser from anywhere – real-time dashboards, alarms, and historical data included free.

LED Indicators keep it simple onsite: PWR (power), RUN (operation), LINK (network), STS (cloud status), plus 3-digit temperature display.

Key Features

• Free Sollae IoT Cloud: Real-time visualization, customizable UI, event alarms, 30-day logging.
• Email Notifications: Threshold-based alerts sent directly to your inbox.
• Compact & Tough: 94 x 57 x 24 mm, 64g, wall/din-rail mountable.
• Optional PT100 Probe: -50°C to +200°C range available separately.

Technical Specifications

The optional is a 3-wire RTD sensor with a temperature measurement range of -50C to +200C.

NOTE: The SIG-5561 device supports PT100 sensors that have a measurement range of -200℃ ~ 850℃ (-328℉ ~ 1562℉). But the measurement range depends on the PT100 sensor. We provide a PT100 sensor that has the measurement range of -50℃ ~ +200℃ as an option. If users need a larger range, use another PT100 sensor.
