3502E | Triconex Digital Input Module

Each TMR Digital Input (DI) module has three isolated input channels which independently process all data input to the module. A microprocessor on each channel scans each input point, compiles data, and transmits it to theMain Processors upon demand. Then input data is voted at the Main Processors just prior to processing to ensure the highest integrity. All critical signal paths are 100 percent triplicated for guaranteed safety and maximum availability. Each channel conditions signals independently and provides optical isolation between the field and the Tricon.Type TMR with Self-TestVoltage 48 VAC/VDCPoints 32, commoned in groups of 8AC Range/DC Range 35-95 VAC/VDCFrequency Range DC or 47-63 HzMaximum Voltage 95 VAC/VDCNominal Turn-On 6-9 mATypical Hysteresi 7 VAC/VDCPoint Isolation 1,500 VDCNominal Input Impedance > 2.9 K
