DESCRIPTION
The premium features of the Apollo Series can now be applied to
measurement of process variables. With its high sensitivity and
programmability, the Apollo Current-Loop Indicator (APLCL) can be set up for
a wide variety of applications. In most plants the APLCL can be used for 90 to
95% of current-loop indicator needs for readout of pressure, flow, temperature,
level and other variables.
The rugged construction and sealed metal front bezel meet the requirements
of NEMA 4/IP65, when properly installed. This allows the APLCL to be used
in dirty, hostile environments and in wash-down areas. In addition, the attractive
flat-black and brushed aluminum front dresses up any control panel.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
SPECIFICATIONS
1.
DISPLAY:
3 1/2-digit (1999), 0.56" (14.2 mm) L.E.D., minus sign displayed
on negative current flow. Decimal points inserted before 1st, 2nd, or 3rd least
significant digits by DIP programming switches.
2.
POWER:
Available for 115 or 230 VAC ±10%, 50/60 Hz, 6 VA.
3.
INPUT SENSITIVITY:
(Numerical Readout Change/mA)
260 units/mA @ 4 to 20 mA input
105 units/mA @ 10 to 50 mA input
(max. allowable input current, 170 mA)
4.
COMPLIANCE:
Voltage drop across input at max. signal current, less than
600 mV for both 4 to 20 and 10 to 50 mA ranges.
5.
INPUT RESISTANCE:

6.
SCALING RANGE:
SPAN
: 32 coarse steps
(binary progression with 5 DIP switches, rear
access)
. Each step providing approx. 8.125 numerical units/mA/step
sensitivity for 4 to 20 mA input and 3.25 units/mA/step for 10 to 50 mA
input. Fine adjust
(front access)
brackets the coarse step increments.
OFFSET
: 16 coarse steps
(binary progression with 4 DIP switches, rear
access)
with ± switch to add or subtract offset. Each step adds or subtracts
approximately 175 from the numerical display for a total offset range of
±2700. Front access fine control brackets the steps.
