Description
PRO NMEA Buffer 1 OPTO Input, 6 ISODrive Outputs, Serial Port, Pluggable Screw TerminalsSafely connect one Talker to six Listeners with full isolation.The Typeapproved NMEA Buffer PRONBF1 Buffer isolates and buffers NMEA 0183 data, with the power to drive multiple devices.Able to distribute up to six identical, amplified streams of data from one source, the NMEA signals are buffered to ensure that each Listener receives the data at the required voltage levels, providing consistent data quality.Isolation of the input and outputs ensures the protection of the source Talker device and Listener devices.The NMEA Buffer has ISODrive™ technology on the outputs and OPTOisolation on the input, which enables you to connect the NMEA 0183 Buffer with complete peace of mind.The stainless steel housing makes the device rugged, sturdy, and gives it increased durability. The metal case also acts as an RF Shield, making the device an ideal addition to commercial installations.To make installation quick and simple, the PRONBF1 features 2part pluggable connectors that allow use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead.The optional strain relief brackets can be provided to ensure reliable professional cable management.Helpful LEDs indicate power, input, and output operation.Features:One OptoIsolated InputSix ISODrive™ outputsOutputs automatically track the input baud rateRS232, RS422 and RS485 Listener compatibleISODrive separates the Listener from the Talker to protect both the PRONBF1 and each connected deviceWide compatibility means simplified installationSimple installation saves time and money and provides peace of mindType Approved (RINA)Technical Specifications:Power SupplyInput Supply Voltage 9 to 35V DCInput Supply Current 150mA max @ 12V DC (all outputs @ full drive into 100Ω loads)Input Protection Continuous reverse polarity and ESD protectionPower Indicator LED, Blue – Indicates unit is functioning correctlyInput Supply Connector Pluggable 2way screw terminal, 5.08mm pitchNMEA 0183 Port – Listener & TalkersNumber of Listener / Input Ports One isolated NMEA 0183 ListenerNumber of Talker / Output Ports Six isolated NMEA 0183 TalkersCompatibility Fully NMEA 0183, RS422 & RS232 compatible.
