Distributed I/O Controller SRM1 The SRM1s high-speed distributed I/O controller is a revolutionary design in PLC control. The SRM1 places all the processing power and control in the ultra compact master unit and allows you to distribute up to 256 points of I/O via a twisted pair network. You can create a distributed I/O network with up to 32 nodes at distances up to 500 meters away. This allows for reduced cabling costs, in- creased flexibility, lower system costs, and optimum efficiency when I/O has to be located away from the CPU. Distributed I/O system supports up to 256 I/O points SRM1 master communicates with up to 32 nodes at up to 500 meters away Twisted pair network allows easy addition of devices and reduces cabling costs High-speed communications at up to 750 kbps Multiple remote I/O options including discrete and analog I/O devices 4k Program memory 2 k Data memory UL/CSA/CE approvals Basic Configuration Peripheral Host device device CompoBus/S Communications Cable Terminator SRM1 Slave Slave Slave 32 Slaves max. 1SRM1 SRM1 Ordering Information CPU/MASTER UNITS Product Appearance Power Peripheral Serial Standards Part number supply port port CPU/Master Unit UL, CSA, DC Yes SRM1-C01-V2 CE (SeeCE (See Note 2.)

Note: 1. Information on EC Directives Individual OMRON products that comply with EC Directives conform to the common emission standards of EMC Directives. However, the emission characteristics of these products installed on customers equipment may vary depending on the configu- ration, wiring, layout, and other conditions of the control panel used. For this reason, customers are requested to check whether the emission characteristics of the entire machine or equipment comply with the EMC Directives. 2. Network power supply: One power supply can be used for communications and I/O over flat cable SCA1-4F10. Multiple power supply: Use separate power supplies for communications and I/O. Flat cable cannot be used for I/O power. Local power supply: Power can only be provided from a single source using twisted-pair cable. 2
