HART interface module HART to SDI-12/

RS-485Modbus

The HyQuest Solutions „HART to SDI-12 Interface“ allows any 4-20mA HART device to be connected to an SDI-12 data logger providing the best accuracy available from the HART protocol.The Hartbeat is available in two models, HBT1 and HBT1 Plus. (See the seperate HBT1 bulletin for details). Dual SDI-12 and 4-20mA output Interface LCD Display Robust powder coated aluminium enclo-sure (IP65) User selectable options Power - +10 V t o +18 V D C Reverse polarity protection. LCD off + Backlight off + Hart on @ 4mA = 32mA min LCD on + Backlight on + Hart on @ 20mA = 118mA max Hart Interface - +16V DC (Even when power source is +10 V ) Current limited to 30mA – in the event of a short circuit. Uses Hart commands to retrieve info and also set configuration. (Allows connection of external Vega Connect Master by providing +16V DC power and no comms – DIP Sw selection) Main SDI - SDI-12 (Conforms to SDI-12 V1.3) Extra SDI - Conforms to SDI-12 V1.3 4-20mA - As a sensor - Range configurable Indicators - LED 1 Blue = Hart Comms Red = Battery Low Green = Battery OK LED 2 Red = SDI-12 #1 comms • LED 3 Green = LCD Board comms User Selectable Options - Internal DIP Switches (refer to instruction manual for details) Connection - Plug-in 6 way screw terminals and Plug-in 3,way screw terminals (refer to instruction manual for details.) Operating Temperature - -400C to +700C Environmental - IP65 Dimensions - 205mm x 100mm x 105mm (L x W x D)
