Description

The 104-AIO12-8 is a low-cost 12-channel analog multifunction I/O board which features an excellent price/performance value for PC/104-based data acquisition. The inherent "selectability" of the card’s onboard features allows the depopulation of unnecessary functionality. This keeps costs down by allowing the user to more precisely specify the board to the application’s unique requirements. The 104-AI12-8 has no outputs while the 104-AO12-4 has no inputs. The 104-AIO12-8 provides eight single-ended or eight true differential analog input channels with 12-bit resolution. 200V common-mode rejection, high input impedance (2MegOhms, typical) and factory pre-settable gain to accommodate low-level sensor inputs are also included. Analog inputs are software programmable for 0-5V, 0-10V, ±5V and ±10V, and optionally factory configurable for 4-20mA. The same ranges are jumper-selected for the four channels of 12-bit analog output. 24 parallel lines of digital I/O, eight of which also provide change-of-state detection, are also provided for a complete, low cost, multifunction data acquisition solution.
