Part Number: IC694BEM321

The IC694BEM321 is a master controller module within the PACSystems RX3i platform, designed to facilitate I/O Link communications with up to 16 slave devices. Acting as a master in GE's proprietary I/O Link configuration, this module can handle 1,024 discrete inputs and 1,024 discrete outputs, making it a vital component for robust industrial automation systems. It can be installed in any I/O slot within the RX3i or Series 90-30 systems; however, optimal performance is achieved by placing it in the main or expansion backplane. The maximum number of I/O links supported is contingent upon the available power supply. For systems with multiple I/O Link master modules, it is essential that they are allocated to separate I/O links to ensure proper functionality. The module is equipped with a replaceable fuse for the +5 volt signal pins utilized by the Optical Adapter cable; a 0.5A fast-blow fuse can be used as a replacement if necessary. Three status LEDs indicate operational and communication health, while the Link Restart pushbutton allows for a system reset in case of link failure. It is important to note that if a fault occurs, all connected slaves must be power cycled before utilizing the Link Restart feature. The IC694BEM321 includes a front-facing module with a 20-pin Honda-type connector, designated for connectivity to the primary slave on the I/O link, and supports RS422/485 compatible signaling for seamless operation.
