Sequent Microsystems Home Automation V4 8-Layer Stackable HAT for Raspberry Pi

Description

The Home Automation HAT uses only pluggable connectors. In addition, the latest release (V4.0 and up) has two new communication ports: 1-Wire and RS485.

The card uses only 5 V power. On-board step-up power supply generates 12 V to power the 0-10 V analog outputs.

A general purpose push-button, wired directly to a Raspberry Pi GPIO pin, can be used to shut down Raspberry Pi without a keyboard, or to force any output to a desired state.

  • Ideal solution for your Raspberry Pi Home Automation projects.
  • Read temperatures in up to 8 zones with analog inputs.
  • Control your heating and cooling system with the 8 onboard relays.
  • Use the 8 optically isolated digital inputs for your security system.
  • Activate the hardware watchdog to monitor and power cycle the Raspberry Pi in case of software lockup.
  • Control four-light systems with the four PWM open-drain outputs (you supply external power up to 24 V).
  • Control four light dimmers using 0-10 V outputs.

Compatibility

The card is compatible with all Raspberry Pi versions from Zero to 4. It shares the I²C bus using only two of the Raspberry Pi’s GPIO pins to manage all eight cards. This feature leaves the remaining 24 GPIOs available for the user.

Power Requirements

The Home Automation card needs 5 V to operate and can be powered from Raspberry Pi or from its own pluggable connector. The onboard relay coils are also powered from the 5 V. An on-board 5V to 12V step-up power supply generates the voltage to drive the 0-10 V analog outputs. A local 3.3 V regulator powers the rest of the circuitry. The card needs 50 mA to operate with all relays off. Each relay needs up to 80 mA to turn on.

Relays

The 8 on-board relays have contacts brought out to heavy duty pluggable connectors, which make the card easy to use when multiple cards are stacked up. Relays are grouped in two sections of four relays each, with one common terminal and one N-O contact for each relay. Relays are rated 10 A/24 VDC and 250 VAC, but due to the board geometry limitation, the relays can switch only 3 A and 24 V, AC or DC. Status LEDs show when RELAYS are ON or OFF.

Stacking Multiple Cards

Up to eight Home Automation cards can be stacked on your Raspberry Pi. Each card is identified by jumpers you install to indicate the level in the stack. Cards can be installed in any order. The three position jumper on the upper right corner of the card selects the stack level.

  • Eight relays with status LEDs and and N.O contacts
