GENERAL DESCRIPTION
Model 2B22 is a high performance, compact voltage-to-current
converter offering 1500V dc input to output isolation in interfacing
standard process signals. The input stage of the model 2B22 is single
resistor programmable to accept voltage ranges from 0 to +1V to 0 to
+10V. The isolated output current range is 4 to 20mA, and the 2B22
can be operated with 0 to 1000
grounded or floating loads.
Using modulation techniques with transformer isolation for reliable
performance, the 2B22 is available in three accuracy selections offering
guaranteed nonlinearity error (2B22L: ±0.05% max, 2B22K: ±0.1%
max, and 2B22j: ±0.2% max) and guaranteed low span drift:
±0.005%/
°
C max, ±0.01%/
°
C max, and ±0.015%/
°
C max, respectively.
The internally trimmed span and offset errors are ±0.1% max for the
2B22L and ±0.25% max for the 2B22J/2B22K. Both span and offset
are adjustable by the optional external potentiometers.
Featuring a wide range, single supply operation (+14V to +32V), the
2B22 provides isolated +28V loop power and is capable of delivering
rated current into an external 0 to 1000
load resistance. The unique
output stage configuration also allows the user to utilize an optional
external loop power supply to interface systems designed for a two-
wire operation.
APPLICATIONS
Model 2B22 has been specifically designed for high accuracy
applications in process control and monitoring systems to offer
complete galvanic isolation and protection against damage from
transients and fault voltages in transmitting information between
subsystems or separated system elements. The 2B22
meets the requirements of the instrument Society of America Std. 50.1
"Compatibility of Analog Signals for Electronic Industrial Process
instruments" for Type 4, Class U isolated current loop transmitters.
In the industrial environment, model 2B22 can serve as a transmission
link between such system elements as transmitters, indicators,
controllers, recorders, computers, actuators and signal conditioners. In
data acquisition and control systems, the 2B22 may act as an isolated
interface between the D/A converter output of a microcomputer and
standard 4 to 20mA analog loops.
DESIGN FEATURES AND USER BENEFITS
High Reliability:
Model 2B22 is a conservatively designed, compact
module capable of reliable operation in harsh environments. To assure
high reliability, the 2B22 has a calculated MTBF of over 270,000
hours and has been designed to meet the IEEE Standard for Transient
Voltage Protection (472-1974: Surge Withstand Capability).
Process Signal Compatibility:
The versatile input stage design with a
single resistor gain adjustment enables the 2B22 to accept any one of
the standard inputs
0-1V, 0-10V, 1-5V; or 1-5mA, 4-20mA, 10-
50mA; and provide standard, isolated 4-20mA output.
Isolated loop Power:
Internal 28V dc loop supply, completely isolated
from the input power terminals (±1500V dc isolation), provides the
capability to drive 0 to 1000
loads and eliminates the need for an
external dc/dc converter.
