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. WIZ550WEB Digital Output Port 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.

WIZ550WEB Digital Input Port

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. WIZ550WEB Digital Input Jumper

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. WIZ550WEB Analog Input Port

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. WIZ550WEB Analog Input Jumper
