Tough Relay from Digital Loggers

The Tough Relay from Digital Loggers combines a durable SPDT power relay, AC current monitor, circuit breaker, energy logger, power meter, and event scheduler in a compact DIN rail-mountable package. It can operate stand-alone with its built-in real-time clock and scheduler, or connect to a microcontroller via serial I/O for remote monitoring and control.

Key Features

• SPDT Power Relay – Rugged AC/DC-rated relay with large contacts and 12A fuse
• Software Circuit Breaker – Programmable overcurrent protection
• AC Ammeter – Built-in current monitoring with energy integration for power metering
• ADC Inputs – Monitored analogue inputs for relay triggering or external DC voltage measurement
• Real-Time Clock – Battery-backed RTC for event scheduling
• Serial Output – RS-232/TTL serial for streaming status, histograms, and logs to a host processor
• FRAM Storage – Non-volatile memory for long-life data logging
• Universal Power – 5–24V DC input, approximately 1W consumption
• DIN Rail Mount – Standard DIN rail form factor for panel installation

Ideal For

• Automated power management and load switching
• Energy monitoring and logging
• Scheduled power cycling for remote equipment
• Microcontroller-controlled relay systems
