This Termination Board (X1-TB) provides direct connection between the I/O Card of the system and X1-Series modules. Signal isolation between system and field is provided by X1-Series galvanic isolators (X1-NIS). The 24 Vdc Power Supply of the X1-TB is connected to two connectors, for redundant power supply.Installation in Zone 2 / Division 2Foxboro FBM200 UIO Card board interfaces8 positions universal board interface for up to 8 channelsLower cables installation and maintenance costsPower supply redundancySingle DIN-Rail mountingSingle loop disconnection to ease maintenance operationsThree port isolation, Field/System/SupplyStatus: ACTIVEChannels: 8Technical DataGeneralNumber of positions8Maximum number of channels8Power Dissipation0 W without modulesSupplyVoltage24 Vdc nom (20 to 30 Vdc), reverse polarity protected, double connectors for redundant power supply, with OR diodes to mix voltagesMax allowed current consumption4 A (as total supply)Connectionscrew type for terminations up to 2.5 mm²Field InterfaceConnectionby polarized plug-in disconnect 8-position screw or push-in spring terminal blocks to accommodate terminations up to 2.5 mm²Max voltage60 VdcSystem interfaceTypeThe system interface sinks currentConnectionone SUB-D 25 poles male connector (requiring female mating connector)Cablesystem cable Type 1Max current500 mA per channelIsolationTest VoltageField/System 2.5 kV; Field/Supply 2.5 kV; System/Supply 500 VEnvironmental conditionsOperating temperaturetemperature limits –40 to +70 °CMax altitude2000 m a.s.l.Storage temperaturetemperature limits –45 to +80 °CMountingTypeHardware included for mounting on single DIN-rail 35 mmWeightabout 500 g, excluding modulesLocationSafe Area/Zone 2/Div. 2DimensionsWidth 133 mm, Depth 143 mm, Height 155 mmCertifications:ATEX: FM ATEX zone 2 X1 Series English Certificate (Europe) - FM23ATEX0039X - FM - 2025-08-13Ex: FM US X1 Series Divisions and Zones English Certificate (North America) - FM23US0073X - FM - 2025-08-12Ex: FM Canada X1 Series Divisions and Zones English Certificate (North America) - FM23CA0055X - FM - 2025-08-12IECEx: FM IECEx X1 Series English Certificate (International) - IECEx FMG 23.0018X - FM - 2025-08-12UKEx: FM UKEx zone 2 X1 Series English Certificate (United Kingdom) - FM23UKEX0040X - FM - 2025-08-14Declarations of Conformity:EU Declaration of Conformity of X1-TB-08-FOX-02UK Declaration of Conformity of X1-TB-08-FOX-02Drawings: 3D drawing available (STP format)Caractéristiques / spécifications techniques :Number of positions: 8Maximum number of channels: 8Power Dissipation: 0 W without modulesSupply Voltage: 24 Vdc nom (20 to 30 Vdc), reverse polarity protected, double connectors for redundant power supply, with OR diodesMax allowed current consumption: 4 A (total supply)Supply connection: screw type for terminations up to 2.5 mm²Field Interface connection: polarized plug-in disconnect 8-position screw or push-in spring terminal blocks up to 2.5 mm²Field Interface max voltage: 60 VdcSystem interface: SUB-D 25 poles male connector, system cable Type 1, max current 500 mA per channelIsolation test voltage: Field/System 2.5 kV; Field/Supply 2.5 kV; System/Supply 500 VOperating temperature: –40 to +70 °CMax altitude: 2000 m a.s.l.Storage temperature: –45 to +80 °CMounting: DIN-rail 35 mmWeight: about 500 g (excluding modules)Location: Safe Area/Zone 2/Div. 2Dimensions: 133 x 143 x 155 mm (W x D x H)
