You can use the four pulse inputs either independently or as two pairs.
Generally, they are used for dual pulse measurement, such as turbine
applications. In dual pulse mode, you can enable level A or B pulse
checking.
Each input has an input range of 1 to 10 KHz. Each channel has live
integrity checking. If cabling faults develop or if the pre-amp power
fails, the system activates a circuit fail alarm.
Table 4-19 shows the dual-pulse input pin connections. Refer to Figure
4-27 for field wiring schematics.
