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 1.4VLow
Over 2.1VHigh
Max Voltage24V
Potential differenceNo. 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
