It provides a watchdog output to monitored output modules and supports power supply monitoring in multiple-PSU configurations, mixed redundant and non-redundant I\/O arrangements, and systems requiring additional watchdog current capacity.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e10302\/2\/1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType Number\u003c\/td\u003e\n\u003ctd\u003e10302\/2\/1 12600\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eWatchdog Repeater Module (WDR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.12 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4 TE x 3 HE (4 HP x 3U rack space)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e5 VDC Supply Current\u003c\/td\u003e\n\u003ctd\u003e35 mA, excluding WDROUT output current\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e24 VDC Supply Current\u003c\/td\u003e\n\u003ctd\u003e25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWDG1 + WDG2 Input Current\u003c\/td\u003e\n\u003ctd\u003e0.1 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMonitored Supply Voltages\u003c\/td\u003e\n\u003ctd\u003e5 VDC and 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRequired Watchdog Current\u003c\/td\u003e\n\u003ctd\u003eRepeater required when current exceeds 900 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e24 VDC Supply Voltage Condition\u003c\/td\u003e\n\u003ctd\u003eSupply output must remain below 37 VDC under any single or double fault condition\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSoftware Version\u003c\/td\u003e\n\u003ctd\u003eVersion 3.00 or later\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApprovals\u003c\/td\u003e\n\u003ctd\u003eCE, TÜV, UL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Connector\u003c\/td\u003e\n\u003ctd\u003eMale DIN 41612, Type F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector Rows\u003c\/td\u003e\n\u003ctd\u003ed, b, z\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Key Coding\u003c\/td\u003e\n\u003ctd\u003eHoles A5, A9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRack Key Coding\u003c\/td\u003e\n\u003ctd\u003eLarge pins A5, A9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHorizontal Bus Connection\u003c\/td\u003e\n\u003ctd\u003eRequired\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eWatchdog Output and Power Supply Monitoring\u003c\/h3\u003e\n\u003cp\u003eThe 10302\/2\/1 monitors the designated I\/O power supply voltages and connects its watchdog output to the watchdog inputs of the corresponding output modules. Installation is required in specific configurations:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMultiple power supply units: One repeater is required for each subsequent 24 VDC to 5 VDC power supply unit, such as PSU 2, PSU 3, or PSU 4.\u003c\/li\u003e\n\u003cli\u003eSpecified power supplies: Required when 24 VDC is supplied through an M24-20 HE or M24-12 HE power supply.\u003c\/li\u003e\n\u003cli\u003eElevated supply voltage: Required when the 24 VDC source can exceed 31.0 VDC. The supply output must remain below 37 VDC under single- or double-fault conditions.\u003c\/li\u003e\n\u003cli\u003eHigh watchdog current: Required when the watchdog current demand exceeds 900 mA.\u003c\/li\u003e\n\u003cli\u003eMixed I\/O redundancy: Generates the watchdog output for non-redundant output modules in configurations combining redundant and non-redundant I\/O.\u003c\/li\u003e\n\u003cli\u003eRedundant Central Parts: Supports 5 VDC monitoring in configurations with redundant Central Parts and non-redundant I\/O when 5 VDC monitoring is otherwise absent.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe module requires a horizontal bus connection. Rack space must be reserved at positions 1, 2, or 11-18 as applicable to the rack configuration. Each repeater must be installed in the same I\/O section as the output modules it monitors.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 10302\/2\/1 be replaced while the power supply is energized?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The module can be exchanged with the power supply switched on. However, the Central Part will shut down during the exchange. In configurations with redundant Central Parts and non-redundant I\/O, both Central Parts will shut down.\u003c\/p\u003e\n\u003cp\u003eQ: Which connector and rack positions does the module require?\u003c\/p\u003e\n\u003cp\u003eA: It uses a male DIN 41612 Type F connector with the d, b, and z rows. It requires a horizontal bus connection and occupies 4 TE x 3 HE (4 HP x 3U). Rack positions must be allocated according to the applicable I\/O rack configuration.\u003c\/p\u003e\n\u003cp\u003eQ: What are the module's power supply requirements?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 35 mA from the 5 VDC supply, excluding WDROUT output current, and 25 mA from the 24 VDC supply. The combined WDG1 and WDG2 input current is 0.1 mA.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVerify rack compatibility and reserve the required 4 HP x 3U mounting space before installation.\u003c\/li\u003e\n\u003cli\u003eConfirm that the horizontal bus connection is available at the intended rack position.\u003c\/li\u003e\n\u003cli\u003eCheck module and rack key coding.
