Codesys PLC Industrial Automation Remote IO Solution PNP Digital IO

CT-121F:16 channel digital input/24VDC/ Sink type/The input high level is valid

Module features
the module supports 16 channels digital input, supports sink input, and input voltage is 24VDC.
the module can collect digital output signal of field equipment (dry contact or active output).
the module can be accessed to 2-wire or 3-wire digital sensor.
the internal bus and field input of the module use opto-isolator.
the module supports the input signal holding function, and the holding time can be set.
the module carries 16 digigtal input channels with LED indicator on each channel.
supports counting function, by adding counting sub-module.
each input channel of the module supports a 32-bit counter with the counting frequency <200Hz.
the module can set the digital signal input filtering time and the byte transmission order of the counter.
each channel of the module can set the counting mode and counting direction independently.
