WIZ550web Baseboard Pinout

WIZ550web Baseboard Callout

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.
