Brand: Yokogawa
SKU: juxta-r-series-relay-input-output-cards

The R Series is DCS-supported status input / output signals interface. Relay I/O cards have 2 channels per card. Up to 16 cards (32 channels total) can be stored in a JIS and EIA conformed mounting nest, and connect with DCS (Yokogawa CENTUM-XL, µ-XL, etc.) by block connection by cable.

The R Series is a DCS-supported status input/output signals interface, consisting of relay input/output cards and a housing nest. It makes insulation for On-Off contact signal of push button switch, limit switch, etc. and transmit the signal to DCS. It also transmits status signal of DCS to field through contact output for On-Off of magnetic valve and start/stop/natural rotate/reverse rotate of motor, etc. Capability of high density mixed mounting of input / output cards, and horizontal and vertical types of mounting nests are available. Mounting nests conform with JIS and EIA specifications.

What are the merits of conditioner nests?

(ns-faq-juxta-11008-select)

These are generally used for connecting a DCS. The advantages are: 1 nest holds 16 units Allows checking while activated Removable card format One power supply for all units

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.)

How is a handy terminal (JHT200) connected to a conditioner that allows range changes?

(ns-faq-juxta-11002-setting)

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).

Can I change settings from a BT200 (BRAIN terminal)?

(ns-faq-juxta-11003-spec)

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?

(ns-faq-juxta-11006-setting)

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...

How much resistance is there for current input?

(ns-faq-juxta-11010-spec)

The resistance is 250 Ω (4–20 mADC). However some computing units also have 100 Ω input.

How many instruments can be connected to a voltage output terminal (1–5 VDC)?

(ns-faq-juxta-11014-spec)

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.

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.

Does the JUXTA VJ series support CCC and GB standards? Can it be used in China?

(ns-faq-juxta-11038-other)

JUXTA VJ series is not a CCC standard scope. Some models of the VJ series have acquired GB standard and can be used in China. Please contact us for applicable models. ...

There may be a 63% or 90% response depending on the manufacturer, but how should I compare these?

(ns-faq-juxta-11020-other)

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...

Please provide information about PCB usage. (JUXTA)

(ns-faq-juxta-11068-other)

PCBs were banned from manufacturing and imports in 1975. JUXTA was first released in 1987, therefore they should not include PCBs.

Is there a warm up time for a signal conditioner?

(ns-faq-juxta-11066-spec)

Yes. To satisfy the performance specifications, you should power the unit for 10–15 minutes.
