USB I/O 24 DIP R Digital I/O Module

The USB I/O 24 DIP R Digital I/O Module is the ROHS-compliant version of our previous USB I/O 24 DIP, of which differences will be outlined in a section below. The module retains the 50-pin Dual Inline Package (DIP) and fits into a standard 50-pin 900mil wide IC Socket. This makes the USB I/O 24 DIPR ideal for rapid prototyping and development work.

The module features 24 5V level signal lines that are individually programmable as input or output. As the module connects to the USB port, multiple modules can be connected to a single PC using a USB hub or hubs. Each module features a serial number, and the
PC can identify each module uniquely, thereby connecting multiple modules for a single application. The outputs of the module can source or sink up to 30mA per I/O, up to a maximum of 50mA per port, to allow for direct connection to a
variety of devices

MODULE FEATURES:

• 24 independently programmable Input / Output Pins Grouped into 3 ports.
• Single module High-Speed Digital Input / Output solution.
• Integrated Type-B USB Connector.
• On-board unique serial number and custom programmable FLASH microcontroller.
• Both USB Enumeration information and Microcontroller can be re-programmed to suit customer needs.
• The module is powered by a USB from the PC or by an external power supply.
• 50-pin Dual In-Line Package Ideal for prototyping.
• Fits into a standard 50-pin 900mil IC Socket. (Supplied with module)
• The virtual COM port driver allows access to a regular serial port.
• An optional DLL-based driver is available.
• Easy to program using popular development languages C, C++, C#, VB, etc.
• Simple command set for easy control of ports and data transfer.

Absolute Maximum Ratings

Subjecting the device to conditions outside these ratings will invalidate the product warranty and may cause
irreparable damage to the device.

• Maximum Voltage on Any Pin (referenced to GND):5.1 V DC
• Minimum Voltage on Any Pin (referenced to GND):.-0.1V DC
• Supply current when USB enumerating: 55mA
• Supply current when running with no load on I/O pins: 32mA
• Total Current to or from Any
• Single I/O Pin: 30mA
• PORT (8 Single I/O make a PORT):50mA
• Total Current in or out of all the module’s I/O pins:200mA

The difference between the two versions is as follows.

USB I/O 24 MK3

• Main Controller Ubicom SX52 (52 pin TQFP) End of Life due to Non-RoHS
• USB Controller FTDI FT245BM/BL
• Mechanicals 68.6mm x 38.2mm
• Expansion Port Header
• Led Functionality to indicate data transfer
• Not RoHS

USB I/O 24 R

• Main Controller Parallax SX48 (48 pin TQFP) RoHS Compliant
• USB Controller FTDI FT245R (28 pin SSOP) RoHS Compliant
• Mechanicals identical to MK3
• No Expansion Port Header
• No LED functionality to indicate data transfer
• RoHS Compliant
• Firmware is identical to MK3 except for identifier ‘?’ returns USB I/O 24 R

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photography lights, angles and display monitors.
