The YTA610 provides high accuracy, stability, and reliability. 

The housing structure adopts reliable dual-compartment structure.

The sensor input can be choice of single or dual inputs. This input

can accept the RTD, thermocouple, ohm, or DC millivolt.

It converts the sensor input to a 4 to 20 mA DC analog signal or

Fieldbus digital signal. HART 7 Protocol or FOUNDATION™ Fieldbus

ITK 6 version are available. The dual input can accept two sensors

calculation of the differential or average value and the sensor backup

function. Sensor backup functions for automatically switches-over from

the primary to the backup upon sensor failure.

By adoption of local parameter switch on the Indicator, it becomes

easy to do the on-site setting work.

YTA610 features include:

• Dual-compartment field-mount housing

• Choice of HART 7. or FOUNDATION™ Fieldbus ITK 6 Protocol

• Local Parameter Setting function (Indicator model)

World-class Optical Performance

• Wavelength range: 600 to 1700nm

• High wavelength accuracy: ±0.01nm

• High wavelength resolution: 0.02nm

• Wide dynamic range: 78dB typ.

• Wide level range: +20 to -90dBm

• Fast measurement: 0.2 sec. (100nm span)

• Applicable to single-mode and multimode fibers

Improved World-class Optical Performance

Standard and High-performance models

There are two models available, Standard and High performance.

The High performance model provides even higher wavelength

accuracy and dynamic range.

High wavelength resolution: 0.02nm

High wavelength accuracy: ±0.01nm

• High performance model: ±0.01nm (C band)

• Standard model: ±0.02nm (C+L band)

Ultra-High dynamic range: 78dB typ.

With the reduced stray-light in the monochromator, AQ6370C

achieves ultra-high dynamic range of typ. 78dB.

Sharper fi lter edge

The high performance model can also achieve a higher dynamic

range within 0.2nm of the peak wavelength. With the sharper

spectral characteristics of the monochromator, spectral signals in

close proximity can be separated clearly and measured accurately.

Stray-light suppression ratio: 80dB typ.

This new specifi cation provides stray-light suppression capability

without the High dynamic mode, which takes a longer measurement

time.  The AQ6370C contributes to shortening the measurement time

with the high stray light suppression ratio.

Wide level range: +20dBm to -90dBm

The AQ6370C can measure high power sources such as optical

amplifi ers and pump lasers for Raman amplifi ers, and very weak

optical signals as well. Measurement sensitivity can be chosen from

seven categories according to test applications and measurement

speed requirements.

• Flexible installation

Base units can be shipped separately from the enclosure and installed into the enclosure at a suitable timing. This

allows a project to perform the acceptance test using the base unit at factory in parallel with field wiring work to the

enclosure at the customer site. And this minimizes the exposure of the base unit to the harsh environment such as

dust, water, and electromagnetic noise by keeping the base unit in the warehouse during field wiring work to the

enclosure.

• N-ESB / Optical ESB bus interface function

This function allows for communicating with the upper-level field control unit and N-IO node. It also allows for

communicating with the lower-level N-IO node.

Uplink:

Downlink:

1 port /N-ESB bus module (N-ESB bus or optical ESB bus)

1 port /N-ESB bus module (N-ESB bus or optical ESB bus)

• Splicing box

This is installed in the enclosure as standard. Connect the optical fiber cable of the optical ESB bus from outside to

the splicing box.

• House keeping (HK) function

Monitors the temperature in the enclosure, the system power and field power output.

• Maintenance function

The node interface unit (NIU) has a Micro-USB maintenance port for maintenance.

The setting of the node address is possible with a NIU Node Number Setting tool.

NIU Node Number Setting Tool is included in the CENTUM VP R6 software media.

• GENERAL

This General Specifications (GS) covers the hardware specifications of an N-IO field enclosure and its

related products (A2NN70D style S2. A2NN60D style S2. A2CB60 style S2. and A2CX100). The N-IO field

enclosure (A2NN70D) [System model (*1): A2ZN70D] is a standardized remote I/O enclosure for outdoor

use, which provides the accessories including field power supply units with optimized design. The N-IO

field enclosure consists of two components, one is a dedicated enclosure with terminal blocks and the

other is a base unit with an N-IO node including field power supply units. It is possible to order the

enclosure (A2CB60) and the base unit (A2NN60D)

[System model (*1): A2ZN60D] individually. In the individual orders, the base unit can be shipped

separately from the enclosure. Then this enables the user to install the base unit into the enclosure at a

suitable timing. This is defined as “Flexible installation”. The flexible installation allows a project to

perform the acceptance test using the base unit at factory in parallel with field wiring work to the

enclosure at the customer site. And the flexible installationminim izes the exposure of the base unit to the

harsh environment such as dust, water, and electromagnetic noise by keeping the base unit in the

warehouse during field wiring work to the enclosure.
