DIN-rail mount Modular Controller with 34 Built-in I/O points and no Operator Interface.Local I/O expansion using OCS-I/O.Introducing Horner’s Modular Controller. These are some of the most flexible controllers available – with individual components placed exactly where you want them – programmed as a single, integrated component using our free, All-in-one software package, Cscape.Modular Controllers are mounted on DIN-rail and support I/O that is snapped on the side, built-in, or both. That means all of your I/O wiring can be buried in the panel, which for many customers is the preferred approach. If your I/O needs are distributed, up to 7 OCS I/O modules each can be remotely located.Connectivity is extensive, with all models supporting industrial protocols including Ethernet/IP (Server UDP), Modbus TCP/IP (Client/Server), Modbus RTU (Master/Slave), CsCAN, FTP; and optional add on protocols: WebMI, CANopen (Master/Slave), BACnet (Server – IP/MSTP), J1939.All models support USB-C for programming. Logic languages supported include traditional Ladder and IEC 6-1131. All models will support Horner’s OCS360 cloud service in a future update – with remote connectivity, push data, long-term data storage, dash-boarding, alarm notifications, and more.The CPU250 (34 built-in I/O) are Micro class products which are an excellent value and are designed for applications where a physical HMI is not required. For HMI Connect support, please see models CPU260 & CPU300.CONTROLLERLogic Memory (Ladder/IEC)2MBLogic Scan Rate0.4 mS/kBVariables (Word-type/Bit-type)50,000/32,768 (16,384 ret)Floating-Point SupportYes (64-bit)AutoTune PID Loops(8 loops)I/OBuilt-in I/O Points34Built-in High Speed I/O4 In (500 kHz) & 2 OutBuilt-in Analog I/Oup to 8 In & 8 OutBuilt-in Analog Type (In/Out)0-10V, 4-20mA, 0-20mATotal I/O Memory (DI/DO/AI/AO)2048/2048/512/512Local Low-cost Relay I/O Expansion8-32 relaysLocal OCS-I/O Expansion7 modulesNetwork OCS-I/O Expansion (maximum)7 modulesETHERNET & INTERNETIndustrial Ethernet ProtocolsEthernet/IP (Server UDP), Modbus TCP (Client/Server)Other Ethernet ProtocolsBACnet (Server – IP/MSTP) opt, FTP (server), SMTP (client)Remote AccessOCS360 Cloud Service, WebMI via HTML5, EnvisionRVUSB & SERIAL PORTSUSB Programming PortUSB CRS-232 Ports & RS-485 Ports1 each on shared RJ45RTU/Modbus (Master/Slave) & ASCIIYesCAN NETWORKINGStandard ProtocolsCsCANI/O Expansion, Peer-to-Peer MessagingYesOptional ProtocolsCANopen, SAEJ1939 (opt)PHYSICAL SPECIFICATIONSTypical Mounting LocationDIN-railHeight (inches/mm)4.917” / 124.9 mmWidth (inches/mm)4.504” / 114.4 mmOverall Depth (inches/mm)1.969” / 50 mmOPERATING SPECS & STANDARDSSupply V (W), Input V10-30VDC (15W), 12/24VDCOperating Temperature-40° to 60°CRelative Humidity (non-condensing)5 to 95%Environmental RatingIP20Model Number: HE959CPU250Configuration: Includes 8 DC In, 10 DC Out, 8 Flexible (Digital or Analog mA/V) Inputs, and 8 Analog Out (4 x mA, 4 x V).
