Instance IN
The IN instances are binary sense instances that will result in a binary state based on the input voltage at the terminal. There are 3 of these instances which act independently of each other. The input switching voltage is 1.4V at the terminal where below this voltage is considered shorted and above this voltage (up to the products rated input voltage) is considered open. The instance type can be configured to fit the environment this product is placed in. For examples for wiring this instance, see How do I wire the zc-io-6?.
Instance Types
| Instance Type | Name | Description |
| 301 | Pushbutton | In this type the instance will act as a push button following the IEC 62386-301 standard. The input will act in a binary sense and no longer detect an analogue voltage. |
| 302 | Absolute Input | In this type the instance will act as a absolute input following the IEC 62386-302 standard. The instance resolution is configurable and will change whether the instance senses analogue voltage or acts as a binary input. |
| 303 | Occupancy Sensor | In this type the instance will act as a occupancy sensor following the IEC 62386-303. The input will not detect a binary state as an indication for if motion is detected and will no longer sense an analogue voltage. |
| 306 | Voltage Sensor | In this type the instance will act as a voltage sensor following the IEC 62386-306 standard. The input will detect the voltage and produce an event value in mV. |
Pushbutton
When the instance is in this type, the input is now sensed as a binary input. The input switching voltage is 1.4V at the terminal where below this voltage is considered shorted and above this voltage (up to the products rated input voltage) is considered open. The instance active state determines if the instance is considered pressed when it is shorted or open.
| Setting | Name | Setting Description | Configuration | Configuration Description |
| 194 | Active State | Controls whether the instance is active when shorted or open | 0 | The instance is pressed when the input is shorted |
| 1 | The instance is pressed when the input is open (default) |
Absolute Input
When the instance is in this type it can act as a analogue voltage sense or a binary sense. When acting as a binary sense, the switching voltage is 1.4V at the terminal where below this voltage is considered shorted and above this voltage (up to the products rated input voltage) is considered open. When acting as a analogue voltage the instances input value is based on the ratio of the input voltage to the configured maximum voltage. The instances resolution and active state are also configurable using the instances settings.
The instance resolution setting controls if the instance acts as a binary sense or analogue voltage sense. For a resolution value of 1, the instance will act as a binary sense. For any other value of resolution, the instance will act as a analogue voltage sense. When acting as an analogue voltage sense the input value is the ratio of the sensed voltage multiplied by the resolution bit mask. The maximum voltage to scale against is configurable by 0.5V increments up to 24V (48). The voltage can be calculated using the following formula.
Where;
- voltage = sensed voltage
- input value = Instance Input Value
- resolution = Instance resolution
- maximum voltage = Maximum configured voltage
| Setting | Name | Setting Description | Configuration | Configuration Description |
| 193 | Resolution | Controls the instances resolution | 1 | The instance is acting as a binary sense with an active high state |
| 2-12 | The instance is acting as an analogue voltage sense (default 10) | |||
| 194 | Active State | Controls whether the instance is active when shorted or open | 0 | The instance is pressed when the input is shorted as a binary sense |
| 1 | The instance is pressed when the input is open as a binary sense (default) |
|||
| 195 | Voltage Scale |
Controls the what voltage the maximum event value should represent, in multiples of 0.5V. Eg, resolution 10 = input value 1023 = 10V = 20 configuration |
1-48 | In multiples of 0.5V, the voltage that should be represented for the maximum input value. (default: 48) |
Occupancy Sensor
When the instance is in this type it acts as a binary sense to detect if motion has been detected. The input switching voltage is 1.4V at the terminal where below this voltage is considered shorted and above this voltage (up to the products rated input voltage) is considered open. The instance active state determines if the instance has detected motion when it is shorted or open.
| Setting | Name | Setting Description | Configuration | Configuration Description |
| 194 | Active State | Controls whether the instance is active when shorted or open | 0 | The instance has detected motion when the input is shorted |
| 1 | The instance has detected motion when the input is open (default) |
