1.0 GENERAL INFORMATION
Model 558B two-wire current-loop indicator accepts 1-5 mA, 4-20 mA, or 10-50 mA
process signals and digitally displays the process variable in percentage or
engineering units of such measurements as pressure, flow, temperature and level.
No separate power supply or power connections are required, since the 558B
obtains operating power directly from the current loop with a voltage drop of less
than 2.5 V. It can tolerate current overdrives up to 200 mA forward and 1000 mA
reverse.
The compact 558B circuit is mounted in a black polycarbonate case with the
standard 1/8 DIN panel-mount bezel and a depth of less than 110 mm (4.33 in).
Five 12.7 mm (0.5 in) high liquid crystal 7-segment digits are used to display
±1999 active counts plus one or two dummy right-hand zeros.
The 558B displays from -1999 to 1999 counts with the option of one or two
dummy right-hand “0” digits. Zero suppression or elevation capability exceeds
full scale. Program jumpers are used to scale the readout for percentage or
engineering-unit display. Both zero and span are fine-tuned with multiturn
potentiometers accessible through the display board, requiring lens removal for
readjustment.
When removed from its case, the 558B can be programmed with gas-tight
jumpers for three input ranges (1-5, 4-20 or 10-50 mA), four coarse zero ranges,
four decimal-point locations and the dummy right-hand zeros. Two additional
jumpers are provided to reverse the span slope so that increasing the input can
cause a reading decrease; thus a 4-20 mA input can be programmed to produce
a 2000 to -18000 reading when one dummy right-hand zero is also used.

3.0 MECHANICAL ASSEMBLY AND INSTALLATION
3.1 SAFETY CONSIDERATIONS
To ensure safe operation, follow the guidelines below:
VISUAL INSPECTION: Do not attempt to operate the instrument if damage
is found.
SIGNAL WIRING: Insert the proper plus and minus signal wires into the plug-in
screw-clamp connector terminals marked plus and minus. Ensure that the wires
are securely clamped in the plug-in connector by rotating the screws in the
plug–in connector clockwise but do not exceed a torque of .5 newton-meter
(.37 pound-foot). Then plug the connector firmly into the socket located on the
rear panel of the meter.
RAIN OR MOISTURE: Do not expose the instrument to condensing moisture.

5.0 CONFIGURATION
The standard 558B meter is factory-configured for an input of 4-20 mA to display
00.0 to 100.0. Field configuration for input current range, decimal point location,
dummy right-hand zero digit, coarse zero range selection, and reverse span slope
may be done by relocating internal push-on jumpers and adjusting the span and
zero potentiometers. Refer to Figure 5-1 for the span and zero potentiometers and
internal jumper locations.
5.1 STANDARD SETUP
Unless the customized configuration option is specified, jumpers are factory-installed
at S1- , S2-C, S1-B, S1-C and the unit is calibrated for 4-20 mA = 00.0 to 100.0.

6.0 CUSTOMER CONFIGURATION AND CALIBRATION
Use this procedure to determine the configuration of the 558B customized setup.
The procedure is general; customers can specify any two current inputs and their
corresponding digital readings. Pin-groups are shown in Figure 5-1.
6.1 FORMULA
Base all your calculations on either the 1-5, 4-20 or 10-50 mA range.
1. Determine the lowest input current, I1, which is specified by the customer:
I1 = mA
2. Determine the highest input current, I2, which is specified by the customer:
I2 = mA
3. Determine the reading, N1, at input current I1, which is specified by the
customer.
N1 = counts
4. Determine the reading, N2, at input current I2, which is specified by the
customer:
N2 = counts
5. Calculate the Gain, G1:
(N2 - N1)
G1 = = counts per mA
(I2 - I1)
(If G1 is greater than 125, it is out of range for a standard unit.)
6. Calculate the Required Zero Range number, RZR:
RZR = N1 - (I1 x G1) =
7. Select the Zero Range required from the following chart where the Required
Zero Range number falls between the upper and lower limits of that range:
ZR1 = -2510 to -1420
ZR2 = -1580 to -420
ZR3 = -470 to +850
ZR4 = +760 to +2000
ZR =

10
6.2 CONFIGURATION PROCEDURES
1. Remove all push-on jumpers.
2. For an input current range of 1-5 mA, no jumper is required.
For 4-20 mA input, install a push-on jumper at S1- .
For 10-50 mA input, install a push-on jumper at S1-J.
3. If N2 (Section 6.1) is less than N1, reverse the signal polarity by removing
jumpers from S1-B and S1-C and reinstalling jumpers at S1-A and S1-D.
4. Select the zero range required (ZR1-4) and install the push-on jumper as
indicated in the configuration chart (Section 5.2).
5. If a decimal point is required (DP1-5), install a push-on jumper as indicated
in the configuration chart (Section 5.2).
6. If one dummy right-hand zero is required, install jumper at S2-A.
7. If two dummy right-hand zeros are required, install jumpers at S2-A, S2-G,
S2- , and S2-J.
6.3 CALIBRATION
1. Apply an input current (I1) and adjust the zero pot (Z) to read N1.
2. Apply an input current (I2) and adjust the span pot (S) to read N2.
3. Repeat steps 1 and 2 as required to set N1 and N2 to within ±1 count.
6.4 FACTORY-SETUP LABEL
The label on the meter shows the factory-configured input and display settings.
If the configuration is changed, use the extra label included with the meter to
indicate the new settings.
