RIS-SP2 VHF IS Two-Way Splitter

RIS-SP2 VHF IS Two-Way Splitter Intrinsically Safe MSHA Certified • RF Branching off Leaky Feeder Cable • DC Blocking and Termination Selection on each Branch via Jumper • 75 Ohm Impedance FEATURES Becker Mining Systems’ two-way splitters enable branching of Leaky Feeder cable in a smartcom® 150IS system. The RIS-SP2 is a fully functional VHF splitter for the frequencies 10-200 MHz. Each branch has jumpers to select its mode of operation: Terminate: 75 Ω Termination. No DC: Blocks DC voltage to/from branch. Normal: Passes RF and DC. The layout rules for smartcom® 150IS systems can be found in the latest version of drawing MSHA-IS-01.
