  • CT-121F: 16 channel digital input/24VDC/ Sink type

    CT-121F: 16 channel digital input/24VDC/ Sink type

    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.

  • CT-124H:32 channels digital input/24VDC/Sink or  Source type

    CT-124H:32 channels digital input/24VDC/Sink or Source type

    CT-124H: 32 channels digital input, sink or source, 34Pin male connector, 24Vdc, counting function supported (counting frequency up to 200Hz)

    ◆ the module supports 32 channels digital input, it supports sink input and the input high level is valid as it could support PNP sensor; it also supports source input and the input low level is valid as it could support NPN sensor.

    ◆ the module could collect the digital output signal of field equipment (dry contact or active output).

    ◆ the module could be connected to 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.

    ◆ after adding counting submodule in ODOT configured software, the counting function is effective.

    ◆ each input channel of the module supports 32-bit counter with counting frequency <200Hz.

    ◆ the module could be set the digital signal input filter time and counter byte transmission sequence.

    ◆ each channel of the module could be set the counting mode and counting direction independently
