Digital Output Port
WIZ550web Baseboard has eight (D0-D7) relay output stage. Below is a photo of basic internal circuit. Jumper, relay NC (Normal close) and NO (Normal Open) can be set.
See the table below for State action.
| Input value | Relay status value | NC output value | NO output value |
|---|---|---|---|
| 0 | OFF | Close | Open |
| 1 | ON | Open | Close |
Output port voltage and current characteristics, see the table below.
| NO | 5A 28VDC | 10A 125VAC | 5A 250VAC |
|---|---|---|---|
| NC | 3A 28VAC | 5A 125VDC | 3A 250VDC |
Digital Input Port
WIZ550web Baseboard has eight (D8 to D15) Photocoupler via a digital input columns. Below is a photo of basic internal circuit. There is no polarity input, and ON/OFF is distinguished from this potential difference between the two input signals.
See the table below for the electrical characteristics of the input.
| Under 1.4V | Low |
|---|---|
| Over 2.1V | High |
| Max Voltage | 24V |
| Potential difference | No. There are two input signals On/Off by potential difference |
Four (D8-D11) digital inputs are connected as shown in tact switch inside the Baseboard, and these connections have select Jumper J23-J26.
Analog Input Port
WIZ550web Baseboard has four (A0-A3) analog input columns. Below is a photo of basic internal circuit. It is possible to simply enter 0 to 12V and has entered in the WIZ550WEB through the internal circuitry.
Two of the Analog Input (A0, A1) have connected with a variable resistor (10K) and a temperature sensors (TC1047AVNB) in the Baseboard, this connection can opt to J26, J28 Jumper.
