IO Ports Description
Digital Inputs
It's compatible with passive switch(dry node) and active level(wet node), for the active level, wet mode, the voltage range as followed:
VCC Voltage | Low Level Range | High Level Range |
24V | 0-17V | 17-24V |
9V | 0-3V | 3-9V |
Analog Inputs: multiple options
Current input : 4~20mA (INZ-IO-6042-I20)
Voltage input:
0~5V,0~10V (INZ-IO-6042-V5), (INZ-IO-6042-V10)
Resistance input: 0~10K (INZ-IO-6042-R10K)
Digital Outputs
Output type: relay output (5A@AC250V/DC30V)
Features
Support DHCP and DNS
The Remote IO Module supports DHCP and DNS to solve IP P management, IP conflict. It can fulfill telecommunication requirements through domain name..

Modbus Communication
Connect the input and output devices on site to INZ-IO-6042, and then the INZ-IO-6042 connect to the Ethernet network, so the host computer could inquiry input signal of input devices and control the relay output of output devices.

Support Web interface and Device management tool to configure device
