Distributed I/O Expansion Module 16 opto-isolated inputs and 16 opto-isolated outputs for SPiiPlus motion controllers
The HSSI-IO16 Module monitors the HSSI communication channel and its own integrity.If the integrity check fails, the module automatically turns off all outputs.
Every module is manufactured under an ISO9001 certified quality management system and meets stringent safety and EMC standards.
The HSSI-IO16 is a modular I/O expansion unit that provides
16 opto-isolated inputs and 16 opto-isolated outputs
fully coordinated with motion.
Up to 4 units of HSSI-IO16 can be daisy chained via each HSSI channel
4 HSSI Channels maximum per controller
64 inputs and 63 outputs per channel.
256 inputs and 252 outputs can be added by using 16 HSSI-IO16 modules.
I/O can be configured as either sink or source in groups of 8
Total current available to each group of 8 I/O is up to 350mA.
All outputs have overload protection.
LED indicates the state of each input and output.

Two-Axis Distributed Interface Module
The HSSI-ED2 module provides a convenient and cost-effective way to interface the SPiiPlus controller with two distributed axes.
With the ED2 performance of the distributed axes is comparable to that of the axes that are connected directly to the controller. The controller samples the remote encoders and updates the drive commands at a rate of 20kHz, providing high-bandwidth servo control, exceptional dynamic tracking, and fast settling time. Another important advantage of the HSSI-ED2 is that the cabling between the distributed axes and the motion control product is reduced to just the single HSSI CAT 5 cable.
The HSSI-ED2 module monitors the HSSI communication channel and its own integrity. If the integrity check fails, the module automatically disables the drives and turns off all the outputs.
