Using the DC2228A, one 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 PHY, leveraging the LTC2874’s high port count and robustness. The LTC2874 offers Hot Swap protected L+ supply outputs, ±50V abs max CQ pins and 8 to 34V operation. The DC2228A conveniently operates with either an external 24V supply or a Power over Ethernet (PoE) system.
An onboard dual-core NXP LPC43 MCU 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, leveraging the LT3669-2’s ±60V line protection and high current driving capabilities – a 300mA step-down regulator and 150mA LDO.
An onboard Atmel SMART SAM3S series MCU 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.
