Introduction The X2-Series X2BI10XD7 Industrial Digital I/O expansion board provides 7 current- sinking 24 V IEC 61131-2 compliant industrial digital inputs with diagnostics and 7 640 mA, 24 V outputs that can be configured as high-side switches or push-pull drivers. The output lines have a dedicated on-board power supply input, independent of the Strato Pi Max power supply.
Features ✓ 12÷28 Vdc dedicated I/O power supply ✓ 7 current-sinking 24 V IEC 61131-2 compliant industrial digital inputs with diagnostics, based on MAX22190 ✓ 7 640 mA, 24 V outputs that can be configured as high-side switches or push-pull drivers for high-speed switching, based on MAX14912/MAX14913 ✓...
Device identification The circuit board is identified by the "StratoExp_D7 R.1.0" markings on the lower left corner of the circuit board (front view). One or more alphanumeric characters may be printed after the version number. CIRCUIT BOARD IDENTIFICATION MARKINGS X2BI10XD7 User Guide...
Hardware setup Connections TERMINAL BLOCKS CONNECTIONS In order to install or remove the expansion board, the plastic DIN rail enclosure must be removed NOTICE Before opening the Strato Pi Max enclosure, disconnect all power sources and any connection to external devices, including USB and Ethernet cables. Follow the Strato Pi Max User Guide installation instructions.
Digital input/output section ✓ DC: nominal voltage between 12 V and 28 V (min=10.5 V, max=36 V) Respect the correct polarity: ground must be connected to I/O V- and positive voltage level to I/O V+. I/O V+ is not required for the inputs. The I/O V- connection is always required. Power and status LEDs This expansion board has four LEDs, visible through the front panel: A.
These protection mechanisms are implemented in the standard Strato Pi Max firmware provided by Sfera Labs. If the user uses custom firmware the protection logic described below shall be implemented. Some use cases may require the implementation of different or additional protection logic, or be subject to other electrical and operational limitations.
Overvoltage protection When an output line of the MAX14912/MAX14913 driver is configured as high-side and set to OFF, if a voltage is applied to that line that is higher than 0.3V + I/O V+, a considerable amount of current will flow from the output to the MAX14912/MAX14913 VDD, and to the I/ O V+ terminal, if it is connected.
I²C Configuration and control registers map Installing one or more Industrial Digital I/O Expansion Board on Strato Pi Max adds the following registers to its I²C map. The registers’ addresses below correspond to the board installed in slot 1. Add 10 for each upper slots, i.e.
