Product Characteristic
CT-122F 16 channels digital input/0VDC/Source type/Input 0V, the input low level is valid
Module features
◆ the Module supports 16 channels digital input, supports source input, the input voltage is 0V and the input low level is valid.
◆ the module could collect the digital output signal of field equipment (dry contact or active output).
◆ the module can be connected to a 2-wire or 3-wire digital sensor.
◆ the internal bus of the module and field input are isolated by optocoupler.
◆ the module supports input signal holding function, holding time can be set.
◆ the module carries with 16 digital input channel LED indicator.
◆ after adding counting submodule, the counting function is effective.
◆ each input channel of the module supports 32-bit counter with counting frequency <200Hz.
◆ the module could set the digital signal input filter time and counter byte transmission sequence.
◆ each channel of the module could set the counting mode and counting direction independently.
