## Description

**Tough Relay** combines the features of a durable power relay, AC current monitor, circuit breaker, energy logger, power meter, and an event scheduler all in a compact DIN package. It can be used stand-alone or connected to a microprocessor via serial I/O.

This DIN rail-mountable power management system is stuffed full of functionality - [from the same folks who brought Adafruit the handy microcontroller-friendly four outlet relay](https://core-electronics.com.au/controllable-four-outlet-power-relay-module.html).

Tough Relay is a smart electromechanical relay with several features:

- A rugged AC- or DC-rated SPDT power relay with large contacts, a 12A fuse, and a software circuit breaker. Takes the place of a delay relay, circuit breaker, and voltage/current monitor.
- Universal power, 5-24VDC, about 1W.
- Built-in AC ammeter with power integration for energy monitoring.
- Monitored ADC inputs used for triggering the relay or measuring external DC voltages.
- A real-time clock and battery for scheduling.
- An RS-232 / TTL serial output for streaming histograms, status reports, etc. to a host processor.
- Long life non-volatile FRAM memory to store logs.
