Módulo E/S digital R-4RTD-8DIDO-2

EthernetRS-485LAN

Ethernet module with 4 inputs from thermoresistances and 8 digital inputs/outputsThe R-4RTD-8DIDO mixed digital module is equipped with two 10/100 Mbps Ethernet ports, supporting both Modbus TCP/IP and RS-485 serial communication with the Modbus RTU protocol. Like all models in the R Series, it is designed to meet flexible cabling requirements, limited installation space, and high I/O density applications with integrated Ethernet networking. R-4RTD-8DIDO offers 4 thermoresistance inputs and 8 digital channels, each of which can be individually configured as a digital input or output. Configuration is via a web server with HTML5 support or DIP switches. The IP address, MAC address, and firmware version associated with the module can be identified or configured on the LAN using the SDD (Seneca Discovery Device) tool.The module can be connected in Ethernet daisy chain mode with fault bypass to ensure Ethernet connection even if a module in the chain fails. In addition, the device has an advanced “ModBUS Passthrough” function, which allows the module to redirect requests from Modbus TCP-IP to RS485, effectively acting as a gateway. 4-input Ethernet module for thermoresistances and 8 digital inputs/outputs.Technical SpecificationsPower supply10..40 Vdc; 19..28 VacMax power consumption3 WIsolation1.5 kVac multi-way, even between RTD inputsLED status indicatorsPowerInput/Output statusSTS (IP address / DHCP)RX / TX (Data receiving/transmitting on RS485)Ethernet TRF / LNK (Packet transit / Ethernet connection)Protection ratingIP20Operating temperature-25..+65°CStorage temperature-30..+85°CHumidity10..90% non-condensingDimensions (WxHxD)106 x 90 x 32 mmWeight170 gEnclosurePC / ABS self-extinguishing UL94-V0 material, black colorConnections3.5 mm pitch terminal block, max wire section 1.5 mm²2x Ethernet 100Base-T ports on RJ451x RS485 port on terminalsInstallationOn DIN rail EN 60715, wall/panel mountProgrammingIntegrated Web ServerDIP SwitchSpecial functionsDual Ethernet Daisy ChainLAN fault bypassUp to 32 Peer-to-Peer Rules (I/O Mirror)Counters with frequency measurementModbus Passthrough (TCP-IP to RS485)Data memoryFeRAM for counter backupCertificationsCE, UKCARTD INPUTSNumber of channels4 independent RTDsType and RangePT100 (EN 60751/A2, ITS-90), -200..+650°CPT500 (EN 60751/A2, ITS-90), -200..+750°CPT1000 (EN 60751/A2, ITS-90), -200..+210°CNI100 (DIN 43760), -60..+250°CCU50 (GOST 6651-2009), -180..+200°CCU100 (GOST 6651-2009), -180..+200°CNI120 (DIN 43760), -60..+250°CNI1000 (DIN 43760), -60..+250°CADC24-bitDIGITAL INPUTS/OUTPUTSNumber of channels8 configurable digital inputs/outputsType and RangeVoltage: ON threshold: > 11 Vdc;OFF threshold: Compliant with IEC61131-2 type 3MOSFET, PNP; Max voltage/current: 0.2 A; 12 ÷ 24 VdcCounters8 retentive 32-bit counters, max frequency 20 HzCOMMUNICATIONInterfaces2x Ethernet ports (with LAN fault-bypass function) 100Base-T on RJ451x RS485 port on terminalsSpeedUp to 115,200 bps (RS485) / 100 Mbps (TCP-IP)ProtocolsModBUS RTU, ModBUS TCP-IP, httpEthernet communication cableUnshielded CAT5 or CAT5eModBUS communicationUp to 128 nodes without a repeater and a max speed of 115 kbpsPower supply: 10..40 Vdc; 19..28 VacMax power consumption: 3 WIsolation: 1.5 kVac multi-way, even between RTD inputsLED status indicators: Power, Input/Output status, STS (IP address / DHCP), RX / TX (RS485), Ethernet TRF / LNKProtection rating: IP20Operating temperature: -25..+65°CStorage temperature: -30..+85°CHumidity: 10..90% non-condensingDimensions: 106 x 90 x 32 mmWeight: 170 gEnclosure: PC / ABS self-extinguishing UL94-V0, blackConnections: 3.5 mm pitch terminal block, 2x Ethernet 100Base-T RJ45, 1x RS485Installation: DIN rail EN 60715, wall/panel mountProgramming: Integrated Web Server, DIP SwitchSpecial functions: Dual Ethernet Daisy Chain, LAN fault bypass, up to 32 Peer-to-Peer Rules (I/O Mirror), Counters with frequency measurement, Modbus Passthrough (TCP-IP to RS485)Data memory: FeRAM for counter backupCertifications: CE, UKCARTD Inputs: 4 independent RTDs, PT100/PT500/PT1000/NI100/CU50/CU100/NI120/NI1000ADC: 24-bitDigital Inputs/Outputs: 8 configurable, IEC61131-2 type 3, MOSFET, PNP, 0.2A, 12-24VdcCounters: 8 retentive 32-bit, max 20 HzCommunication: 2x Ethernet, 1x RS485, ModBUS RTU/TCP-IP, http, up to 128 nodes
