Smart Relays with Universal Inputs 8-Layer Stackable HAT for Raspberry Pi

FEATURES Four relays with HALL effect sensors on loads Switch and measure AC/DC currents up to 10A Monitor load failure, compute load power, limit load current Four Analog inputs reading temperature from 10K thermistors, or Four Digital inputs reading dry contact or 24V opto-isolated signals Transition counters to 4kHz on all inputs Input counters with cumulative or PPS (pulse per second) reading up to 4kHz 2 x Quadrature encoder inputs reading up to 4000 PPS PWM inputs on each channel, reading both the fill factor and the frequency Enhanced 24V power supply delivering up to 5A at 5V to Raspberry Pi Switch loads of 10A and 250V on all four outputs Hardware watchdog power cycles the Pi on software lockup NO and NC contacts on all relays Status LEDs on inputs and outputs Switch loads of up to 10A and 240VAC/24VDC Eight layer stackable to 32 relays and 32 inputs RS485/MODBUS port Raspberry Pi reset push button Pluggable Connectors 30-16 AWG wires Uses only I2C port (address 0x15..0x0e
