Digital Input Soft-Devices
Digital Input Soft-DevicesCompared to a PLC or other I/O product where you need to purchase a specific hardware module designed for the type of digital input that you are using, with Soft-I/O, it is all configured!
Soft-I/O supports either sourcing or sinking sensors, sometimes called positive logic and negative logic or PNP and NPN sensors. You simply use the Soft-I/O module setup page with your browser and set the type of circuit you need.
In addition, Soft-I/O supports industry standard 24VDC sensors or 5VDC TTL-level devices. Of course, because Soft-I/O can provide power on any pin, hooking up a three-wire proximity sensor could not be easier. Three wires, three pins. You are done! Compare that to the seven wires and additional power supply with a PLC or PAC. Soft-I/O has the advantage!
OverviewEach configured Versatile Digital Input Soft-Device provides one contact state digital input. You might choose Versatile Digital Input Soft-Device if you have a device that does not fit with the description of other available Soft-Devices. Generally, a Versatile Digital Input Soft-Device behaves like a pushbutton or proximity switch, but your device might have characteristics that do not exactly fit either of those devices. A Versatile Digital Input Soft-Device has two contacts. You may connect the two wires to any two Soft-I/O pins or you may connect one wire to the same pin as other Versatile Digital Input Soft-Devices and then connect the second contact to any other Soft-I/O pin, thus saving pins. You may configure the input pin to source current or sink current. It's up to you. Just make sure that the common contact is the same level. Of course, Soft-I/O will guide you to make sure that you do not accidentally connect it up incorrectly. It's that simple! Overview Each configured Relay Contact Input Soft-Device provides one contact state digital input. A single relay may have one or more contacts. If the relay contacts are "double throw" then you will have three wires, one common, one normally closed and one "normally open". You may connect the two wires from any one set of contacts to any two Soft-I/O pins or you may connect one wire to the same pin as other contacts and then connect the second wire to any other Soft-I/O pin, thus saving pins. You may configure the input pin to source current or sink current. It's up to you. Just make sure that the common contact is the same level. Of course, Soft-I/O will guide you to make sure that you do not accidentally connect it up incorrectly. It's that simple! OverviewEach configured Pushbutton Digital Input Soft-Device provides one contact state digital input. A pushbutton has two contacts. You may connect the two wires to any two Soft-I/O pins or you may connect one wire to the same pin as other pushbuttons and then connect the second contact to any other Soft-I/O pin, thus saving pins. You may configure the input pin to source current or sink current. It's up to you. Just make sure that the common contact is the same level. Of course, Soft-I/O will guide you to make sure that you do not accidentally connect it up incorrectly. It's that simple! OverviewEach configured Proximity Sensor Soft-Device provides one contact state digital input through a two or a three wire interface. Compared to wiring a proximity sensor to a PLC or conventional I/O system where you need to wire the power conductor to the positive side of the power supply and the ground conductor to the negative side of the power supply, with Soft-I/O, you simply hook up two or three wires to any pins of the module. Soft-I/O supplies the power, ground and accepts the signal, whether it is sourcing or sinking or even open collector! What could be simpler? OverviewEach configured Limit Switch Soft-Device provides one contact state digital input. A limit switch has two contacts. You may connect the two wires to any two Soft-I/O pins or you may connect one wire to the same pin as other digital inputs and then connect the second contact to any other Soft-I/O pin, thus saving pins. You may configure the input pin to source current or sink current. It's up to you. Just make sure that the common contact is the same level. Of course, Soft-I/O will guide you to make sure that you do not accidentally connect it up incorrectly. It's that simple!
IMPORTANT SAFETY NOTE: Limit switches are connected to Soft-I/O for INFORMATION ONLY! Good engineering practice requires that you follow local codes. Such codes generally require that all limit switches must UNILATERALLY ACT to remove power from potentially dangerous circuits. XiO requires that good practices be followed and that all limit swiches must act to unilaterally remove power. Often, two-pole limit switches are employed where one pole acts to remove power from the circuit while the second completely isolated set of contacts is connected to Soft-I/O to inform Soft-I/O of the limit condition. XiO does not sanction any exceptions to this rule and advises users to follow applicable codes. OverviewEach configured Dry Contact Input Soft-Device provides one contact state digital input. A single dry contact may have one or more contacts. If the contacts are "double throw" then you will have three wires, one common, one "normally closed" and one "normally open". You may connect the two wires from any one set of contacts to any two Soft-I/O pins or you may connect one wire to the same pin as other contacts and then connect the second wire to any other Soft-I/O pin, thus saving pins. You may configure the input pin to source current or sink current. It's up to you. Just make sure that the common contact is the same level. Of course, Soft-I/O will guide you to make sure that you do not accidentally connect it up incorrectly. It's that simple!
