JUXTA W Series Signal Conditioners
Notice: This product was discontinued on Mar 31, 2022. See these replacement products:

Compact size, versatile mounting, and microprocessor based high performance capabilities makes the W Series an excellent choice for almost every application. The specifications of W Series signal conditioners are as same as F Series signal conditioners except for power supply voltage, second output and case width.

Details

  • Compact design for space saving. 72 mm (H) x 48 mm (W) x 127 mm (D).
  • Field configuration (WA5, WH2, WH5, WM1, WR5, WT5, WS1)
    A field configuration of the microprocessor based F Series are possible to set, change and monitor the range, zero/span, burnout, etc. from your PC (with VJ77 PC-based parameters setting tool).
  • Minimize the stock of spare units
    For example, model WT5 thermocouple input signal conditioners can be set their input type, input range, etc. by PC (with VJ77). One unit of WT5 can support 8 types of thermocouples.
  • Wired through the front-panel terminals, so the conditioner can be checked even if the lines are live.
  • Versatile I/O specifications meeting a wide range of applications.
  • Single and dual output models available
    Second output (1 to 5 V DC) is optionally available (except for WA0A, WC0A, WH0V).

They have the following advantages: Enables rack, DIN rail, or wall-mounting Enables checking of signals through operating status and live wire status (assuming the person checking the signals has experience with that)   ...
Can I change the burnout operation?
(ns-faq-juxta-11001-spec)
This is possible if it is a microprocessor type converter. You will need a handy terminal to make the change. (VJR6, VJT6, VJS2, MR6, MT6, MS2, and others cannot be changed.)
F and W series: dedicated 3-pin cable D series: dedicated 5-pin cable VJ, J, and M series computation unit: 5-pin cable + modular conversion (E9786WH, sold separately).
If it is a model that allows range changes, it is possible just like from a JHT200. However, the type of cable is different from the one that comes standard, so you will need to purchase another cable. 3-pin cable: model F9182ED 5-pin cable: model F9...
How do I change settings?

Using the following settings tool, you can change the settings listed in the user's manual that came with the conditioner. Handy Terminals JHT-100 and JHT-200 BRAIN terminal BT200 (requires cable, sold separately) VJ77 Parameter Setting Tool...
The resistance is 250 Ω (4–20 mADC). However some computing units also have 100 Ω input.
You specify it for current pulse input. The resistance you specify depends on the specifications of the transmitter (mainly the rated current of the open collector). The internal load resistances are 200 Ω, 500 Ω, and 1 kΩ, and 0.5 ...
IPTS-68: This is an international standard from 1968 where R100/R0=1.3850 that was used by the JIS from 1989 to 1997, but currently it is not in use. ITS90: An international standard from 1990 where R100/R0=1.3851, and used by the JIS from 1997 to th...
The input impedance of typical voltage input type instruments is 1 MΩ. By contrast, the allowable load impedance for voltage output is 2 kΩ or more, therefore the maximum number of units that can be connected is 500.
The input impedance of typical current input type instruments is 250 MΩ. By contrast, the allowable load impedance for current output is 750 kΩ or more, therefore the maximum number of units that can be connected is 3.
What does response speed **ms(10-90%) mean?
(ns-faq-juxta-11019-other)
It means the time until the output reaches 63% when input is applied in 10 Ω 90% steps.
The open collector needs a power supply. Use one within the maximum allowable load. ...
The total resistance ≥ zero side resistance + span resistance.
What is the output on burnout?
(ns-faq-juxta-11023-spec)
When UP, 106% of the output range or more; when DOWN, -6% or less.
What happens on a "burnout OFF"?
(ns-faq-juxta-11024-spec)
When input is interrupted it reaches ±OVER, but which of these is uncertain.
The F series has 30 steps. The W series has 40 steps. The M/VJ series has 59 steps.
On the M series you can select 50, 100, or 200 ms. On the F, W, and VJ series you can select 100 or 200 ms. (The VJXS can support 50 ms.)
It is with plug-in types. It is also sold separately.
Using a first-order lag or moving average computing unit helps suppress noise. You can use the following for this: M series plug-in type signal conditioners, VJ series compact plug-in type units, or F/W series front panel terminal type computing unit...
You can do this with a limiter or broken-line approximation function. You can use the following for this: M series plug-in type signal conditioners, VJ series compact plug-in type units, or F/W series front panel terminal type computing units. The br...

Resistors come with isolators that have terminal block format current input specifications. Please attach it to the input terminals before use.
A 90% response time is equivalent to 2.3 times the duration of a 63% response time.
What does "time constant" mean?
(ns-faq-juxta-11021-term)
In the case of conditioners, time constant reflects the response speed. In terms of a transfer function, it is expressed as OUT=INΩ(1-e EXP(-t/T)). OUT: output, IN: input, e: natural log, T: time constant, t: elapsed time When the elapsed time...
PCBs were banned from manufacturing and imports in 1975. JUXTA was first released in 1987, therefore they should not include PCBs.
Yes. To satisfy the performance specifications, you should power the unit for 10–15 minutes.
