XG5500 & XG4500: I/O Expansion for XG5000 & XG4100 The XG5500 and XG4500 are two pcb's stacked together, an I/O pcb and either a XG5000 or XG4100. This combination can be installed in a Smart enclosure which can also fit all the X-Graph LCD's (except 10.4"). 104 screw contacts, with pluggable screw connectors Two types of connectors: horizontal (Ex: left and right rows), vertical (Ex: top and bottom rows) 72 multi-purpose I/O pins. Each pin is both input and output Input pins are protected for +/-30 Volt signals Inputs have selectable pull-up/down voltage with jumpers Outputs can sink 500mAmp up to 30Volt, typically used to power relays 72 inputs, max. 63 outputs Rabbit 3000 & Asix I/O pins can be routed to buffers (XG5500) with jumpers 2 Rabbit interrupt pins 4 Rabbit quadrature decoder pins 12 Asix output pins, 5 Asix input pins 24 inputs can be opto-isolated (factory option) XG5000 HVOUT pins are routed to 4 screw contacts, adding 4 more outputs XG5000/XG4100 RS485 and RS232C signals are routed to 8 screw contacts ADC inputs are routed to 8 screw contacts, with optional buffering One XG5000 high-precision ADC chip signals can be routed to 8 screw contacts Special features: GSM/GPRS module GPS module 2x5 pin boxed headers for RS232C cables xgBUS expansion connector Expansion: a second XG5500 board can be daisy-chained. This adds another 72 multi-purpose I/O pins. Up to 6 xgBUS expansion modules can be added with each 8 mulit-purpose I/O pins The XG5500/XG4500 perfectly fits a Smart enclosure with the 3.6"/4.3"/5.6"/5.7" LCD's:
