Function | Description |
---|---|
Free-Run Refreshing | With this I/O refreshing method, the refresh cycle of the NX bus and I/O refresh cycles of the NX Units are asynchronous. |
CT Allocation | This function is used to assign each CT input to a corresponding control output. |
Reading CT Currents | This function reads CT inputs as heater currents or leakage currents. |
Heater Burnout Detection | This function detects heater burnouts. A heater burnout is detected if the control output is ON and the heater current is equal to or less than the heater burnout detection current. |
SSR Failure Detection | This function detects SSR failures. An SSR failure is detected if the control output is OFF and the leakage current is equal to or greater than the detection current. An SSR failure is a failure that is caused by an SSR short-circuit. |
Time-proportional Output | This function controls a control output by using the manipulated variable from the host controller as a duty ratio. You can also specify the minimum pulse widths and execute immediate output commands. |
Load Rejection Output Setting |
This function performs a preset output operation when the Heater Burnout Detection Unit cannot receive an output set value due to a communications error between the host and the Communications Coupler Unit or due to an error on the NX bus. |
Load Short-circuit Protection |
This function is used to protect the output circuits of the Heater Burnout Detection Unit when an external device short-circuits. This function is supported only by the NX-HB3201. |
