Functioning under the acronym WROB, this board provides fused power distribution and integrated voltage feedback monitoring for relay output circuits in critical industrial control environments. It supports both AC and DC voltage sensing across multiple ranges, allowing control systems to continuously monitor circuit integrity without requiring external measurement tools.\u003c\/p\u003e\n\u003ch3\u003ePower Distribution and Voltage Feedback\u003c\/h3\u003e\n\u003cp\u003eThe board features integrated 3.15 A default fuse protection combined with feedback sensing logic to safeguard relay output loops. It handles a versatile voltage matrix including 24 VDC, 48 VDC, 125 VDC, 120 VAC, and 240 VAC circuits. Built-in galvanic isolation barriers isolate outputs to prevent electrical noise transmission into sensitive downstream control electronics.\u003c\/p\u003e\n\u003ch3\u003eSystem Architecture and Terminal Integration\u003c\/h3\u003e\n\u003cp\u003eDesigned to interface directly with GE's TRLY relay module series, the IS200WROBH1A routes power through dedicated terminal board hardware. It supports connection to TDBS, TDBT, and SRLY hardware, as well as TDBTH2, TDBTH4, and TDBTH6 series terminal boards. The board supports simplex, dual-redundant, and Triple Modular Redundant (TMR) architectures, maintaining fault-tolerant operation in safety-critical turbine trip and control loops.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\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\u003eIS200WROBH1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eMark VI \/ Mark VIe Speedtronic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRelay Fuse and Power Sensing Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Acronym\u003c\/td\u003e\n\u003ctd\u003eWROB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDefault Fuse Rating\u003c\/td\u003e\n\u003ctd\u003e3.15 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage Feedback Ranges\u003c\/td\u003e\n\u003ctd\u003e24 VDC, 48 VDC, 125 VDC, 120 VAC, 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Hardware Compatibility\u003c\/td\u003e\n\u003ctd\u003eTRLY relay family\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Terminal Boards\u003c\/td\u003e\n\u003ctd\u003eTDBS, TDBT, SRLY, TDBTH2, TDBTH4, TDBTH6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Configurations\u003c\/td\u003e\n\u003ctd\u003eSimplex, Redundant, TMR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eGalvanic isolation for all outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Range\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature Range\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to 85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Options\u003c\/td\u003e\n\u003ctd\u003ePanel or rack installation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What power ranges can the IS200WROBH1A monitor?
