8-port IO-Link reference design kit
Users can quickly evaluate an end-to-end IO-Link v1.1 system, complete with all required hardware, cables and software. The DC2228A is a complete 8-port IO-Link master reference design that uses two LTC2874 quad master ICs to implement its IO-Link v1.1 physical interface (PHY), using the LTC2874’s high port count and robustness – Hot Swap protected L+ supply outputs, ±50V abs max CQ pins and 8V to 34V operation.
The DC2228A operates with either an external 24V supply or a Power over Ethernet (PoE) system. An onboard dual-core NXP LPC43 microcontroller runs the DC2228A’s protocol stack, while a TEConcept software Control Tool operates the board directly from a Windows PC or remotely over Ethernet for more accurate factory floor simulation. Any IO-Link device, including the DC2227A, can connect to the DC2228A.
The DC2227A is a complete IO-Link device reference design that uses an LT3669-2 device transceiver IC for communication and for powering an onboard temperature sensor, light sensor and incandescent lamp, exploiting the LT3669-2’s ±60V line protection and high current driving capabilities – a 300 mA step-down regulator and 150 mA LDO. An onboard Atmel SMART SAM3S series microcontroller runs the DC2227’s protocol stack, while TEConcept I/O Device Description (IODD) files support both IO-Link and SIO device operation. Any IO-Link master, including the DC2228A, can operate the DC2227A.
The DC2228A is priced at $599 and the DC2227A is priced at $299.
