TRICONEX 3623T Ethernet interface card

Each axis output is an optically isolated solid state switch. It turns on or off according to the logic state sent to it by the CPU. When the switch turns on, current flows through the switch. When the switch turns off, current flow stops. These outputs are intended to interface with the drive enable and drive reset inputs. When an output is turned on current can flow through the switch in either direction. This allows the outputs to be connected in a sink or source configuration. For safety reasons, all outputs turn off (no current flow) when a scan loss condition

DC Input Theory of Operation (Axis, AUX, and General Connectors)

 Each input is guaranteed "on" at 14 to 30 VDC and guaranteed "off" at 0 to 5 VDC; polarity doesn't matter. Its on/off state is converted to a corresponding logic 1 or 0. This logic state is transmitted through the system bus to the CPU module, where the processor uses it as data in the ladder program. The logic side of the input is optically isolated from the field side. The shaded blocks in the figure that follows show the limits specified by the IEC. The lines show the maximum and minimum V/I of the inputs in this module. The voltage/current curve in this graph shows that the input module is well within the IEC Type 1 limits.
