The ODOT CT-124D is a 32 channel digital input that support high-level input, and could be connected to PNP sensor. The CT-124D also support low-level input, and could be connected to NPN sensor. This module can collect the digital output signal (dry contact or active output) of the field devices.  The input channels can also be connected to the 2-wire or 3-wire digital sensor and 32-bit counter for each channel, the counting frequency < 200Hz.

The ODOT CT-124D can be easy integrate with SCADA, PLC, PAC and PC based software systems for a wide range of industrial automation, measurement and process control applications.
