Control your heating and cooling system with the 8 onboard relays. Stackable design - add an additional 8-Relays board to control your sprinklers or a 4-Relays board to control high voltage appliances. 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.

Due to the large number of I\/Os, the previous version used a 40 pin, right-angle header. By removing the N-C contacts of the relays (seldom used), Sequent made enough room on the periphery for pluggable connectors with just a minor increase in board dimensions. \u003cbr\u003e\u003cbr\u003eDespite the crowded layout, they also added a DC-DC, 5V to 12V step-up power supply to power the 0-10V outputs. Now you can control four dimmers without the need for an external 12V power supply!\u003cbr\u003e\u003cbr\u003eSequent also added a general-purpose push-button wired directly to a Raspberry Pi GPIO pin. You can write a script that captures the pin state and use it to turn on a relay or an output, or to shut down the Pi when a keyboard and monitor is not available.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eEight relays with status LEDs and pluggable connectors\u003c\/li\u003e\n\u003cli\u003eEight layer stackable\u003c\/li\u003e\n\u003cli\u003eEight 12-bit A\/D inputs - 250 Hz sample rate, 0-3.3V\u003c\/li\u003e\n\u003cli\u003eFour 13-bit DAC outputs (0-10V dimmers)\u003c\/li\u003e\n\u003cli\u003eFour PWM 24V\/4A open-drain outputs\u003c\/li\u003e\n\u003cli\u003eEight optically isolated digital inputs\u003c\/li\u003e\n\u003cli\u003eContact closure\/Event counters up to 500 Hz\u003c\/li\u003e\n\u003cli\u003eFour Quadrature Encoder inputs\u003c\/li\u003e\n\u003cli\u003e26 GPIOs from Raspberry Pi available\u003c\/li\u003e\n\u003cli\u003ePluggable Connectors 26-16 AWG for all ports\u003c\/li\u003e\n\u003cli\u003eOn-board hardware watchdog\u003c\/li\u003e\n\u003cli\u003eOn-board resettable fuse\u003c\/li\u003e\n\u003cli\u003eReverse power supply protection\u003c\/li\u003e\n\u003cli\u003eBrass standoffs, screws and nuts included\u003c\/li\u003e\n\u003cli\u003eHardware self-test (with optional loop-back cable)\u003c\/li\u003e\n\u003cli\u003eOpen-source hardware, schematics available\u003c\/li\u003e\n\u003cli\u003e32-bit processor running at 64MHz\u003c\/li\u003e\n\u003cli\u003eUses only I2C port (address 0x28..0x2f ), all GPIO pins available\u003c\/li\u003e\n\u003cli\u003eWorks with any Raspberry Pi from ZERO to 5\u003c\/li\u003e\n\u003cli\u003eECCN Code EAR99\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew for v 4.0\u003c\/strong\u003e - 1-Wire and RS485\u003c\/li\u003e\n\u003cli\u003e\nCommand line \u003c\/li\u003e\n\u003cli\u003ePython Library\u003c\/li\u003e\n\u003cli\u003eNode-RED Nodes\u003c\/li\u003e\n\u003cli\u003eDomoticz Plugin\u003c\/li\u003e\n\u003cli\u003eOpenPLC example PSM integration\u003c\/li\u003e\n\u003cli\u003eArduino Library\u003c\/li\u003e\n\u003cli\u003eFirmware Update\u003c\/li\u003e\n\u003cli\u003eCODESYS Driver\u003c\/li\u003e\n\u003cli\u003eOpenPLC module\u003c\/li\u003e\n\u003cli\u003eHome Assistant Integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe card is compatible with all Raspberry Pi versions from Zero to 4.

The tip is +5V and the ring is ground. The onboard relay coils are also powered from the 5V. A local 3.3V regulator powers the rest of the circuitry.

After power-up, the watchdog is disabled and becomes active after it receives the first reset.\u003c\/p\u003e\n\u003cp\u003eThe default timeout is 120 seconds. Once activated, if it does not receive a subsequent reset from Raspberry Pi within 2 minutes, the watchdog cuts the power and restores it after 10 seconds.\u003c\/p\u003e\n\u003cp\u003eRaspberry Pi needs to issue a reset command on the I2C port before the timer on the watchdog expires.
