Plug-in terminal block TBE-D5001-HRT-003

powerplastic

This Termination Board with Enclosure (TBE) allows the remote monitoring of any HART®-compatible 4/20 mA field loop. This is achieved by one locally mounted HART® Multiplexer Modem 5700 series and by interface connectors to access field smart devices. The single TBE-D5001-HRT-003 Termination Board supports 64 channels, extendable with additional units (up to 4) to manage all 256 channels available on the HART® Multiplexer Modem 5700 series. The Mux unit connects, via the RS-485 interface, to an external PC running an FDT-based software package (PACTware™, etc.) through a dedicated Device Type Manager (DTM). The PC can communicate with multiple Mux units, located on different boards, in a multi-drop RS-485 mode. The HART® Termination Board TBE-D5001-HRT-003 is SIL 3 certified as non-interfering with the signal loops. The 24 Vdc Power Supply of the TBE is connected to two plug-in terminal blocks, for a redundant power supply.SIL 3 / SC 3Installation in Zone 2/Div. 2HART® Multiplexing Board of up to 64 analog signals (extendable to 256)4/20 mA loops isolated with dual capacitors (short circuit proof)Dedicated terminal to connect RS-485 cable shieldDouble terminal to ease RS-485 cable multi-dropLower cables installation and maintenance costsRedundant power supplyMounting hardware provided for single DIN Rail mounting kitTechnical Specifications:Number of positions: 1 x HART® Multiplexer Modem 5700 seriesMaximum number of channels: 64 on a single board, extendable to 256 with 4 boards and 1 HART® Multiplexer Modem 5700 series.
