Modulo I/O digitale R-4RTD-8DIDO-2

EthernetRS-485LAN

Ethernet module with 4 RTD inputs 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 communication and serial RS485 with ModBUS RTU protocol. Like all models in the R Series, it is designed to meet the needs of flexible wiring, limited installation spaces, and high I/O density applications with integrated Ethernet networking. R-4RTD-8DIDO offers 4 RTD inputs and 8 digital channels, each individually configurable as a digital input or output. Configuration is performed via an HTML5-supported web server or via DIP-switch. 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 in the event of a module failure in the chain. Additionally, the device features the advanced "ModBUS Passthrough" function, allowing the module to redirect requests from Modbus TCP-IP to RS485, effectively acting as a gateway.Power supply10..40 Vdc; 19..28 VacMax absorption3 WIsolation1.5 kVac multiway also between RTD inputsStatus LED indicatorsPowerInput/Output StatusSTS (IP address / DHCP)RX / TX (Data reception/transmission on RS485)Ethernet TRF / LNK (Packet transit / Ethernet connection)Protection degreeIP20Operating temperature-25..+65°CStorage temperature-30..+85°CHumidity10..90% non-condensingDimensions (lxhxd)106 x 90 x 32 mmWeight170 gEnclosurePC / ABS self-extinguishing UL94-V0, black colorConnectionsTerminal block 3.5 mm pitch, cable section max 1.5 mm²2x Ethernet 100 base T ports on RJ451x RS485 port on terminalsInstallationOn DIN rail EN 60715, wall / panel mountingProgrammingIntegrated Web ServerDIP SwitchSpecial functionsDual Ethernet Daisy Chain connectionLAN fault bypassMax 32 Peer to Peer Rules (I/O Mirror)Counters with frequency measurementModbus Passthrough (TCP-IP to RS485)Data memoryFeRAM for counter backupCertificationsCE, UKCARTD INPUTS Number 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°CADC24bitDIGITAL INPUTS/OUTPUTS Number 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 VdcCounters8x 32-bit counters, max freq 20 HzCOMMUNICATION Interfaces2x Ethernet ports (with LAN fault-bypass function) 100 baseT on RJ451x RS485 port on terminalsSpeedUp to 115,200 bps (RS485) / 100 Mbps (TCP-IP)ProtocolsModBUS RTU, ModBUS TCP-IP, httpEthernet communication cableCAT5 or CAT5e unshieldedModBUS communicationUp to 128 nodes without repeater and max speed 115 kbpsPower supply: 10..40 Vdc; 19..28 VacMax absorption: 3 WIsolation: 1.5 kVac multiway also between RTD inputsStatus LED indicators: Power, Input/Output Status, STS (IP address / DHCP), RX / TX (RS485), Ethernet TRF / LNKProtection degree: 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: Terminal block 3.5 mm pitch, max 1.5 mm²; 2x Ethernet 100 base T on RJ45; 1x RS485 on terminalsInstallation: DIN rail EN 60715, wall/panelProgramming: Integrated Web Server, DIP SwitchSpecial functions: Dual Ethernet Daisy Chain, LAN fault bypass, Max 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 channels; PT100, PT500, PT1000, NI100, CU50, CU100, NI120, NI1000ADC: 24bitDigital Inputs/Outputs: 8 configurable; Voltage ON >11Vdc, OFF Counters: 8x 32-bit, max 20HzCommunication: 2x Ethernet (LAN fault-bypass), 1x RS485; Up to 115,200bps (RS485), 100Mbps (TCP-IP); ModBUS RTU, ModBUS TCP-IP, http; CAT5/CAT5e cable; Up to 128 nodes without repeater, max 115kbps
