The ProDAQ 5716 is a 1U high rack-mountable signal conditioning box for standard 19 in. racks. It provides signal conditioning for up to 16 strain gage or ICP sensors. Either one ProDAQ 3416 16-Channel ADC Function Card or up to two ProDAQ 3424 8-Channel 24-bit Sigma-Delta ADC Function Cards can be connected to the unit.
The bridge signal conditioning provides a per-channel programmable excitation voltage of up to 20 V by allowing the positive and negative excitation voltage to be programmed individually between 0..10 V (positive side) and 0..-10 V (negative side) with the current limited to 50 mA per channel. By using remote sense lines per channel any losses due to lead resistance will be automatically compensated. Built-in high-precision resistors of 120 and 350 Ohm as well as sockets for user-installable resistors allow for flexible quarter and half-bridge completion.
Each input channel is equipped with a shunt calibration resistor and provisions for removing bridge offset voltage. A trifilar common mode filter will remove any unwanted high-frequency common mode signals. Each channel also contains selectable AC/DC coupling and ICP signal conditioning circuitry. Both TEDS class 1 and class 2 are supported.
