CT-121F 16DI Module Kỹ thuật số ngõ ra 16 Kênh 24VDC Sink của ODOT

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.
