Figure 1-1. Model 508B

1.1 DEFINITION/APPLICATION

Model 508B is a signal powered, two-wire current-loop indicator that accepts 1-5 mA,
4–20 mA, or 10-50 mA process signals and digitally display (±2000 active counts) the process
variable in either percent or in engineering units for such parameters as pressure, flow,
temperature, and level.

1.2 FEATURES

In-field Programmability

Input ranges (1-5 mA, 4-20 mA, or 10-50 mA) are selected by push-on jumpers. Three decimal
points and a dummy right-hand zero may also be selected by push-on jumpers. Zero and
span may be fine tuned with precision, 25-turn potentiometers. Positive slope response may
be changed to negative slope response (e.g. , +6000 to –18000) by simply changing two other
push-on jumpers.

1
 Signal Powered

Model 508B obtains operating power directly from the current loop, requiring a drop of less
than 2.5 V or 2.5 mW at 1 mA.

Electrical Isolation/Overrange Protection

The 508B is electrically isolated from its case and is immune to most sources of electrical
noise encountered in process-control environments. In the event of input overrange currents,
the 508B can tolerate 250 mA in the forward direction and 1000 mA reverse.

Vibration/Shock/Water Resistance

Low mass and multi-point circuit board support give excellent vibration and shock resistance.
Sturdy, die-cast construction, polyurethane paint,and full fluorosilicone gasketing ensure a
virtually waterproof case.Circuit boards are conformally coated for added humidity protection.

Mounting Versatility

The 508B-1 may be mounted in a control room on either American or European relay tracks
with snaptrack adaptors. The unit can be wall mounted using an available bulkhead adaptor or
mounted in an explosion-proof enclosure for wiring compatibility with other equipment in
hazardous environments. Both the 508B-2 and the 508B-3 may be connected directly to a
conduit with a "T" junction box.

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.

This instrument will meet the requirements of certain FM safety certifications for hazardous
environments. In order to meet these requirements the appropriate intrinsic safety barrier must
be included in the installation to limit the voltage and current that may be introduced in the
hazardous environment.

EXERCISE CAUTION: Due to certain current loop installations, high common mode voltages
may be present on the loop circuits. Become familiar with the possible hazards that your circuit
may present before installing this meter or, to be safe, remove all sources of power to the
circuit while installing.

RAIN OR MOISTURE: Do not expose the instrument to condensing moisture.

 The 508B is packaged in a small, rugged, die-cast, zinc-alloy case designed to fit 3" I.D. or
larger housings, requiring less than 2" of height.

Three basic 508B configurations (508B-1, 508B-2, and 508B-3) provide mounting versatility.

The 508B-1 provides for surface, track, or explosion-proof housing mounting and is
connected with a 3-terminal, #6 screw barrier strip (beneath the display window).

The 508B-2 is equipped with a 1/2" EMT conduit fitting on the case side beneath the display.
The fitting has two 0.3 millimeter long, #18 stranded insulated wires passing through a
neoprene moisture plug for hookup to junction boxes with standard wire nuts.

The 508B-3 is equipped with a 1/2" NPT conduit fitting on the case side beneath the display.
The fitting has two 0.3 mm long, #18 stranded insulated wires passing through a neoprene
moisture plug for hookup to junction boxes with standard wire nuts.

3.4 STANDARD MOUNTING

Tapped holes on the back of the 508B case provide for custom mounting to a flat surface;
integral flanges on the back of the case provide for standard 8TK2 relay track mounting. For
flat surface mounting, use #6 hardware. For 8TK2 relay track mounting, simply push onto
track.

The following optional adaptors provide additional mounting options:

1. Adapter plate for surface mount with two #8 front-entry screws through keyhole slots or for
push-mount into TR2/2TK relay track. (Option MAT1)

2. Rail clamp for push mount onto DIN EN 50 022 relay track. (Option MDT1)

3. Spring retainers for mounting in 76.4 to 88.9 mm (3 to 3.5 in) inside diameter explosion-
proof housings. (Option MXS1)

4. Wire brackets for mounting the 508B above a transmitter in a single housing.

WARNING: Input currents in excess of protective limits can damage your meter

4.1 508B-1

The 508B-1 has a 3-terminal barrier strip on the front of the case below the display window.
The signal inputs are marked with a "+" or a "–" symbol. The third terminal (case ground) is
marked with a "/ / / " symbol. Use of a shielded cable, properly dressed, is recommended.

4.2 508B-2 and 508B-3

Both the 508B-2 and 508B-3 come equipped with a male conduit fitting on the side of the
case. The 508B-2 fitting is 1/2" EMT; the 508B-3 fitting is 1/2" NPT. Each conduit fitting is
plugged with a rubber stopper. Two 0.3 millimeter long, #18 stranded insulated wires are
passed through each stopper. The two wires are white and black. The black wire is the "+"
signal input; the white wire is the "–" signal input. Either unit can be hooked up using
standard wire nuts.

DP1 Decimal point 1.999

DP2 Decimal point 19.99
DP3 Decimal point 199.9
DRHZ Dummy right-hand zero

G Gain expressed in counts per mA

I1 Lowest input current in mA
I2 Highest input current in mA

N1 Reading in displayed counts at input current I1

5.2 CALCULATION

NOTE: An alternate FS calculation procedure is given in Section 5.3

1. Base all calculations on one of three ranges: 1 mA to 5 mA, 4 mA to 20 mA, or 10 mA to

50 mA. Write results of calculations in blanks provided below each procedural step.
2. Determine the lowest input current, I1, specified by the customer:
I1 = _________mA
3. Determine the highest input current, I2, specified by the customer:

4. Determine the reading, N1, at input current, I1, specified by the customer:
N1 = _________counts
5. Determine the reading, N2, at input current, I2, specified by the customer:
N2 = _________counts
6. Calculate the gain (G1):

G = (N2 - N1) = ( - ) counts per mA

(I2 -I1) ( - )

7. Calculate the required range number:

RN = N1 - (I1 x G) =_________

NOTE: If G is greater than 500, it is out of the operating range for the standard unit.

1. If the current range chosen in either Section 5.2 Step 1 or Section 5.3 Steps 1 and 2
equals either 4 mA to 20 mA or 10 mA to 50 mA, install a push-on jumper as indicated in
Table 5-1.
2. If N1 (5.2 Step 3 or 5.3 Step 3) is more positive than N2 (5.2 Step 5 or 5.3 Step 4),
