SIGNAL CONVERTER PCE-SCI-E

Signal converter for electrical signals, isolated, for industrial applications

Isolated signal converter for electrical signals. Accepts a wide range of AC and DC voltages, with ranges from 50 mVac/dc up to 600 Vac/dc, and a

wide range of AC and DC current signals, from 5 mAac/dc up to 5 Aac/dc. The instrument can be congured to measure frequency from any of the

AC voltage and AC current signals accepted. Unipolar and bipolar signals accepted for DC voltage and DC current signals.

Congurable output in 4/20 mA (active or passive) or 0/10 Vdc. Universal power supply from 18 to 265 Vac/dc. 3 way isolation between input, output

and power circuits. Circuit isolation prevents ground loops and transient propagation, protecting remote equipment and signal integrity.

signal ranges to specic values required. Conguration through front push-button keypad. Front information displays available for conguration and

system information (input signal value, output signal value, congured label, signal percentage and process value).

Built-in ‘ ’ functions to manually generate low and high output force

signals, to validate remote instrumentation during installation. ‘SOS’

mode to help on critical maintenance and repairs. Congurable power

frequency rejection lter. ‘ ’ function to block non-authorized Password

access to ‘conguration menu’.

3. Additional information

When the marks ‘ ’ or ‘Attention Risk of electrical shock’

appear, read the documentation for information about the

nature of the risk.

PCE Instruments | www.pce-instruments.com

If this is the rst time you are conguring the instrument, below are

the steps to follow during a rst installation. Read all the

manual sections in order to have a full and clear view of the

characteristics of the instrument. Do not forget to read the

installation precautions at section 17.

1. Install the instrument at the DIN rail

2. Read how to operate the instrument (see section 10)

3. Connect the input, the output and the power terminals (see section 9).

4. Congure the input and output signals

• choose a predened conguration code (see section 8)

• introduce the code at the instrument (see section 13.1)

5. If

needed, customize the input and output signal ranges (see section 13.4)

6. If needed, congure the display reading (see section 13.5), the key ‘UP’

(5) ‘force’ menu (see section 13.6), and the key ‘ ’ ( ) ‘ ’ function LE 3messages

(see section 13.7),

7. If needed, block access to the ‘conguration menu’ (see section 13.8)

4. Installation and start-up

To measure electrical signals in AC and DC and provide a standard

process signal in 4/20 mA or 0/10 Vdc. Accepts signals from current

shunts, signals from DC batteries of 12 Vdc, 24 Vdc, 48 Vdc, ..., signals

from tachometric dynamos of ±60 Vdc, power lines of 230 Vac, 115 Vac,

48 Vac, 24 Vdc, AC leak currents of down to 5 mAac and below, 50 and

60 Hz frequency signals from AC power lines, signals from X/5 and X/1

current transformers.

5. Typical applications

The instrument includes a congurable ‘ ’ function that provides messages

advanced information about the system, available to the operator with a

single click at the front key ‘ ’ ( ).LE 3

This information is helpful during start-up, installation, system

verication, routine maintenance and troubleshooting, as messages and

values provide information on the actual input and output signal value,

actual percentage of the input signal compared to the full scale and

scaled process values.

This information is available at any time, and is displayed sequentially

when requested. Access to this information reduces maintenance

time, improves time invested in failure location, and helps for an easy

resolution of the problem.

Additionally, each instrument can be assigned a custom label code of up

to 8 characters (see Table 1), that can be displayed at the front display

or at the messages sequence, making system identication of each

instrument an easy task.

To congure the ‘ ’ function, see section 13.7.messages

The instrument includes a congurable ‘SOS mode’ function that provides

a way to manually congure a xed output signal. This output signal

remains xed, independent of the input signal value or sensor state.

This function allows to perform urgent maintenance or repair tasks at the

input section of the system, for example replacing sensors, shunts, or

deactivating power lines, while the instrument still provides a controlled

signal that allows for the process to continue its activity, under human

surveillance. When the maintenance or repair task has been performed,

the instrument can be taken back to the standard working mode, where

the output signal is proportional to the input.

When manually activated, the ‘ ’ generates the output signal SOS mode

congured, and the front display remains ashing with the message

‘ ’. All other systems are disabled, which means that :SoS

• no error messages will be shown on display

• no key ‘ ’ ( ) ‘ ’ menu is accessibleUP 5fast access

• no key ‘ ’ ( ) ‘ ’ function is accessibleLE 3messages

• no ‘Eco’ mode activates

Only key ‘ ’ ( ) is accessible, to access the ‘SQ <conguration menu’

(eventually this access can be password locked) in order to deactivate

the ‘SOS mode’. Deactivation of ‘SOS mode’ must be performed manually

by conguring the function to ‘oFF’.

To congure the ‘ ’ function, see section 13.8.SOS mode

Labeling examples: for an application with multiple engine control,

where voltage and frequency are being measured for three engines, and

converted to 4/20 mA for retransmission to PLC or SCADA. Six PCE-SCI-E

converters are being used, to measure 0/300 Vac and 45/55 Hz. Each

PCE-SCI-E can be congured the following label for easy identication :

• Label for engine 1 frequency measurement : Eng1.hZ

• Label for engine 2 frequency measurement : Eng2.hZ

• Label for engine 3 frequency measurement : Eng3.hZ

• Label for engine 1 voltage measurement : Eng1.Vac

• Label for engine 2 voltage measurement : Eng2.Vac

• Label for engine 3 voltage measurement : Eng3.Vac
