It functions as a Serial Link Controller, providing the necessary infrastructure for serial communication interfaces. The module is designed to accept a pluggable personality module (PMOD), which defines the specific serial protocol requirements, such as RS-232, RS-485, or RS-422.\u003c\/p\u003e\u003cp\u003eThe module features two primary ports on the front panel: J1, an RS-232 programming port for interface with a personal computer, and J2, an applications port for connecting to third-party serial devices. The J2 port includes a software-controlled tri-state enable input (TX-ENA) for managing RS-485\/RS-422 data transmission, controlled via the UART Modem Control Register.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSerial Link Controller base unit for Ovation DCS\u003c\/li\u003e\n\u003cli\u003eSupports pluggable personality modules (PMOD) for flexible protocol selection\u003c\/li\u003e\n\u003cli\u003eDual-port configuration: J1 (Programming) and J2 (Applications)\u003c\/li\u003e\n\u003cli\u003eSoftware-controlled tri-state enable (TX-ENA) for RS-485\/RS-422 transmission\u003c\/li\u003e\n\u003cli\u003eCompatible with R1120 CPU systems\u003c\/li\u003e\n\u003cli\u003eDielectric isolation (1,000 V AC\/DC) between channels and logic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePower generation and distribution control\u003c\/li\u003e\n\u003cli\u003eWater and wastewater treatment facilities\u003c\/li\u003e\n\u003cli\u003eSteam and gas turbine governor synchronization\u003c\/li\u003e\n\u003cli\u003eGenerator protection relay data integration (SEL\/GE Multilin)\u003c\/li\u003e\n\u003cli\u003eExcitation system monitoring and adjustment\u003c\/li\u003e\n\u003cli\u003eBoiler management and burner sequencer interlocks\u003c\/li\u003e\n\u003cli\u003eCompressor skid data acquisition (vibration, temperature, surge)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1C31166G02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eEMOD + PMOD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported CPU\u003c\/td\u003e\n\u003ctd\u003eR1120 CPU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Transfer Rate (RS-485)\u003c\/td\u003e\n\u003ctd\u003eUp to 3.125 Mbps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e5 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e0 to 55 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 degC to +70 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-55 degC to +85 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity\u003c\/td\u003e\n\u003ctd\u003e5% to 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure power is disconnected before installing or removing the module from the rack.\u003c\/li\u003e\n\u003cli\u003eUse the appropriate personality module (PMOD) for the required serial protocol.\u003c\/li\u003e\n\u003cli\u003eFor RS-485 loops, install 120-ohm end-of-line termination resistors to prevent signal reflections.\u003c\/li\u003e\n\u003cli\u003eGround cable shields at one end only, typically at the cabinet entry point, to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003eVerify pinout alignment for TX+, TX-, RX+, and RX- lines when connecting to target machinery.\u003c\/li\u003e\n\u003cli\u003eFor CE-certified systems, ensure application port cables are less than 10 meters in length.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the 1C31166G02 module?\u003c\/h3\u003e\u003cp\u003eIt is an Emerson Ovation DCS Serial Link Controller base unit used to facilitate communication between the DCS network and external serial devices.\u003c\/p\u003e\u003ch3\u003eWhat is the function of this module?\u003c\/h3\u003e\u003cp\u003eIt acts as a communication gateway, enabling the DCS to interface with third-party PLCs, intelligent field devices, and various subsystems in industrial environments.\u003c\/p\u003e\u003ch3\u003eWhat is the specific application of the 1C31166G02?\u003c\/h3\u003e\u003cp\u003eIt is an EMOD assembly typically used in conjunction with R1120 CPU systems within power generation and process control applications.\u003c\/p\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":50910037278972,"sku":"1C31166G02","price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/9983\/1292\/files\/wm_1_f917de6c-85c1-4b93-a1bb-8521b39267ae.jpg?v=1785639760","url":"https:\/\/www.electronicplc.com\/products\/ovation-1c31166g02-serial-link-controller","provider":"Electronic PLC","version":"1.0","type":"link"}
