1. Input Ports

Input ports are interfaced with a 5mm spaced terminal block which has 8 terminals. Every output port is isolated by photocoupler and supports wet contact, dry contact, NPN transistor and PNP transistor input.

WET contact

Voltage conditions in wet contact is as follows:

division condition
maximum DC input DC 30V
ON more than DC 3V
OFF less than DC 1.5V

Refer to the following figure for connection with your device.

layout_03

Dry contact

An input port is ON under being short circuit between the port and DI.G port in this type. It means additional power should be supplied between DI.V and DI.G. Refer to the following figure for connection with your device.

NPN Transistor Connection

Refer to the following figure for connection with an NPN transistor.

layout_05

PNP Transistor Connection

Refer to the following figure for connection with a PNP transistor.

2. Slave ID Switch

The slave ID is used when PHPoC board, which is called master, identifies each smart expansion board. Each smart expansion board, which is connected to one PHPoC board, should have a unique slave ID. The slave ID can be set one of the numbers from 1 to 14 by 4 DIP switches as follows:

3. LED

PES-2402 has 6 on-board LEDs.

LED Description
PWR turned ON with stable power supply
STS setting a valid slave ID > repeat On/Off in every second
setting an invalid slave ID > blinks fast
without communication with PHPoC > Off
0 turned ON with detecting input 0 is ON
1 turned ON with detecting input 1 is ON
2 turned ON with detecting input 2 is ON
3 turned ON with detecting input 3 is ON
