The NIR-O Full Spectrum Analyzer is a dispersive NIR spectrometer with an IECEX/ATEX certified designed for Class 1 Div 1 and Div 2 environments. Every NIR-O comes equipped with Modbus for communicating with a distributed control system (DCS). For customers that require 4-20mA outputs, or other analog or digital, I/O Guided Wave has engineered an optional accessory I/O enclosure.

The M508plus UV-VIS Process Spectrometer is an EX IIC T4 compliant design developed for the polymer industry. The IP65 rated enclosure can include up to 16 custom digital and analog I/O and Modbus. There is no need for an external accessory enclosure.

How Many Channels Are Included on Each Module?

Each Digital Input module can accept up to 4 input channels.

• If you require only 1 digital input, then you need 1 Digital Input module. You will then have the ability to add up to 3 more inputs in the future.

Each Digital Output module can process to 4 answers or outputs.

• If you only have 2 measurement parameters, then 1 Digital Output module will meet your needs and allow up to 2 more outputs in the future.

Each Analog Input module can accept up to 2 input channels.

• If you require only 1 analog input, a Wika RTD to monitor process temperature, then 1 Analog Input module will provide the ability to add up to 1 more input in the future.

Each Analog Output module can process up to 2 answers or outputs.

• If you have 3 measurement parameters, then you need 2 Analog Output modules.
