Overview 5 (40)
2 Overview
2.1 Introduction
The Netbiter I/O Extender series provides a solution for distributed I/O requirements. The I/O
system consists of stand-alone digital and analog input/output modules connected together on
a RS-485 two-wire multi-drop network.
The modules communicate using the Modbus RTU protocol. The 32-bit ARM CPU in the mod-
ule provides high speed data processing and fast communication turnaround times. Multiple
baud rates are selectable, from 2400 to 115200 baud.
All I/O modules fit directly onto an industry standard DIN rail. All modules have a minimum isola-
tion of 1000 VAC rms between the field and logic.
The modules are equipped with status LEDs to indicate the status of the inputs and outputs.
This visual indication assists with fault finding and diagnostics.
2.2 Data acquisition
The primary use of the Netbiter I/O Extender modules is for data acquisition in combination with
a Netbiter EC or WS gateway. The Netbiter gateway acts as a Modbus master which retrieves
and sends data from the Netbiter I/O Extender modules.

General/Common Characteristics 6 (40)
3 General/Common Characteristics
3.1 Dimensions
• The module clips directly onto an industry standard DIN rail (EN 50022).
• Field wiring is on the front of the module via a plug-in connector.
• Module power and RS-485 communications wiring are on a separate plug-in connector on
the bottom side of the housing.
• Allow at least 25 mm in front of and below the module to accommodate the wiring.
• Ensure that the space above and below the module is sufficient to provide adequate
ventilation.

General/Common Characteristics 7 (40)
3.3 EMC Considerations
The I/O modules will usually be installed in an enclosure along with other devices that generate
electromagnetic radiation, such as relays and contactors, transformers, motor controllers, etc.
Electromagnetic radiation can induce electrical noise in both power and signal lines. Direct radi-
ation into the module can also have a negative effect on the system.
Appropriate grounding, shielding and other protective steps should be taken at the installation
stage to prevent interference. Protective steps include control cabinet grounding, module
grounding, cable shield grounding, protective elements for electromagnetic switching devices,
correct wiring, as well as the consideration of cable types and their cross sections.
• Use screened twisted pair RS-485 cable with the screen grounded at one point.
• Use screened I/O, T/C, and RTD cables, with the screens grounded at one point as close
as possible to the I/O module.
3.4 Network Termination
Transmission line effects often present a problem on data communication networks. These
problems include reflections and signal attenuation.
If it should be necessary to eliminate reflections from the ends of the cable, the cable can be ter-
minated with a resistor across the line equal to its characteristic impedance. Both ends should
be terminated, as propagation is bi-directional. In the case of an RS-485 twisted pair cable, this
termination is typically 120 Ohms.
