Appendix G. Maximum Sampling Rates of Sensor-Based I/OIBM System/7 Installation Manual-Physical Planning, GA34-0004 provides detailed informationabout sampling rates of the various types of sensor-based I/O. As there are infinitecombinations of loads, voltages, currents, and line length which effect sampling rates, thefigures presented here are maximum and for reference only. GA34-0004 should beconsulted for specific applications.I/O type Description of application Max bits/secondDI Voltage sense (isolated) for logic level signals, short distance, high speed. 300,000Voltage sense (non-isolated) for logic level signals, short distance, high speed. 185,000Voltage sense for logic level signals, medium distance, medium speed. 10,000Voltage sense for high level signals, medium distance, medium speed.1'0,000Voltage sense for logic level signals, long distance, high speed. 300,000Voltage sense for high level signals, long distance, high speed. 300,000Contact sense. 250Response timeDO Low power group 5.8 psecMedium power group (non-isolated)3.7 /lsecMedium power group (isolated)5.8 psecContact group4 msecAOSettling time40 psecMax points/secondAl Models B 1 and E2 200Model Cl (high level inputs) 20,000Model Cl (low level inputs) 14,000Model Cl (automatic gain selection) 7,000Models DI and El 100Maximum Sampling Rates of Sensor-Based I/O G-1
