 The PES-2602 4-Port Digital Input Board is a Smart Expansion Board for PHPoC P4S-347 or P4S-348 V2 Shields which is designed to monitor the on/off state of high-voltage devices.

After stacking on a PHPoC P4S-347 or P4S-348 V2 Shield with an Arduino Uno or Mega, this board can be controlled by Arduino using the PHPoC library.

Each 4-Port Digital Input Board carries four photocouplers. A single Arduino Uno/Mega can support multiple 4-port Digital Input Boards.

Two different types of terminal blocks are available, based on the direction of the terminal screws. S-type can be screwed from the side, convenient when the multiple boards are stacked. T-type is screwed from the top of the board. The wire termination blocks are on the side of the board in both models.

PHPoC Smart Expansion Boards for ArduinoSmart Expansion boards for PHPoC P4S-347 or P4S-348 V2 Shields provide the additional hardware and firmware to boost Arduino Uno and Mega microcontrollers with advanced capabilities (e.g. control high-voltage devices, control/monitor motors with high accuracy).

They communicate with Arduino Uno/Mega via a defined set of commands and need to be stacked above a PHPoC [WiFi] Shield 2 (P4S-347 V2 or P4S-348 V2), firmware version of 1.4.0 or above, in order to interface with Arduino.
