The input voltage is 24/48 V DC, and each module has 2 input points.

This card can receive pulse signals generated by external devices, convert them into digital signals, and transmit the signals to the control system for processing. It can accurately measure parameters such as pulse frequency and amplitude, providing precise data support for system control and monitoring.

It is mainly applied in industrial automation fields such as electric power, petroleum, and chemical industry involved in the Emerson Ovation Control System. For instance, in the electric power industry, it can be used to measure the speed pulse signals of generators.
