Description
The V116 and V132 are compact,
4 digit indicators (with alarms)
that fit 1/16 and 1/32 DIN cutouts,
respectively. They accept temperature
inputs from J, K, T, L, N, R,
S, C, B, and Platinel II type
thermocouples and two-wire Platinum
100 Ohm (Pt100) RTDs. Process
variables such as 4-20mA or
ranges within -12 to 80mV can
also be measured. Other thermocouple
types such as D and E and custom
curves can be configured at
the factory. Voltage ranges
up to 0-10V can be measured
with the optional (model SUB2-1V1)
adaptor.
Three
programmable setpoint alarms
can be field configured as high
or low, non-latching and high
or low or new, latching. The
new alarm indicates when a latched
alarm has not been acknowledged
and the measured value crosses
the setpoint trip level a second
time. Alarm hysterisis (deadband)
can be configured from 1 to
9999 process variable units.
The
alarms can be linked to either
the relay output or the digital
I/O terminals. The digital I/O
terminals can be configured
for remote alarm acknowledgment.
When configured as an output,
those terminals will provide
a TTL signal or drive an optional
(model SUB2-1R7) relay. These
alarm outputs can be configured
in combination (e.g., one or
all three alarms linked to the
relay) and will operate in fail-safe
(i.e., normally energized) or
non-fail- safe modes. Additionally,
the display can be configured
for password protection, limiting
operator access to any or all
func- tions. An alarm blocking
function is also configurable
to prevent alarm tripping during
process or start-up.
Thermocouples,
two-wire RTDs and mV inputs
can be accepted into the indicator.
Current signals such as 4-20mA
are input using the 2.49 Ohm
shunt resistor, included with
the indicator and mounting hardware.
Other shunt resistor values
can be used to measure higher
current levels provided the
produced signal is within the
-12mV to 80mV input range. Similarly,
voltage inputs such as 0-10V
can be measured using the optional
attenuator (model SUB2-1V1).
The input can be scaled as desired
for display. Offsets and two
point slope adjustments are
fully programmable to compensate
for sensor variances.

Application
The V116 and V132 are excellent
for temperature and process
variable measurement especially
when panel space is limited.
Extremely compact and efficient,
the NEMA 4X, plug-in from front,
panel mount indicators can fit
in the smallest enclosures or
OEM panels.
The
field configurable VisiPak indicators
make an ideal standard- ized
solution for a variety of temperature
measurement and on- off control
applications. For example, either
the V116 or the V132 can be
used to control the heating
and cooling elements in an oven
or environmental control system
using two setpoints for high
and low temperature limits.
Similarly, a 4-20mA pressure
signal can be monitored and
the setpoints can be used to
control or alarm the gas pressure
or liquid level in a tank or
vessel. Weight, flow, pressure,
temperature, speed, position
and rate are just some of the
process variables that can be
accurately displayed and moni-
tored with these highly compact
and effective units.
