With over 2.19 million IO-Link nodes installed worldwide, this new reference design kit addresses the growing demand for larger networks by reducing the number of ICs, development costs, and time to market. Users can quickly evaluate an end-to-end IO-Link v1.1 system, along with all the necessary hardware, cabling, and software.
The DC2228A is an 8-port IO-Link master reference design that uses two LTC2874 quad master ICs to implement its IO-Link v1.1 physical interface (PHY). It leverages the LTC2874's high port count and robustness, which includes hot-swappable L+ power outputs, CQ pins up to ±50V, and operation between 8V and 34V. The DC2228A is practical to operate with either an external 24V power supply or a Power over Ethernet (PoE) system. An embedded dual-core NXP LPC43 microcontroller runs the DC2228A's protocol stack, while TEConcept's software control tool can control the board directly from a Windows PC or remotely via Ethernet for more accurate production floor simulation. Any IO-Link device, including the DC2227A, can be connected to the DC2228A.
The DC2227A is a complete IO-Link reference design that uses an LT3669-2 device transceiver IC to communicate with and power an embedded temperature sensor, light sensor, and incandescent lamp. It leverages the LT3669-2's ±60V line protection and high-current handling capabilities, along with a 300mA buck regulator and a 150mA LDO. An embedded Atmel SMART SAM3S series microcontroller runs the DC2227's protocol stack, while TEConcept's I/O Device Description (IODD) files enable compatibility with
IO-Link and SIO devices. Any IO-Link master, including the DC2228A, can work with the DC2227A.
