The 78CS2 features a new high efficiency D/S design that requires less current from the power supply and substantially reduces heat generated on the CCA. The D/S channels include ON/OFF output capability, individual reference inputs for each channel, and rotation with start and stop angles. The card can drive small Torque Receivers directly without booster amplifiers or external amplifiers can be added to drive up to 30 VA. In addition to the enhanced D/S functions this card also features a new generation of S/D capabilities that include programmable Bandwidth, S-R selection, LOS & LOR thresholds, angle change alert, various interrupts, and the ability to read real time incoming signal and reference voltage levels. Along with the Synchro/Resolver simulation and measurement features, this card may also be configured with other I/O modules. Selections can be made from functions such as A/D, D/A, Digital & Discrete I/O, Signal Generators, RTD, Serial Data busses, LVDT and DLV
