2B20 General Description

Model 2B20 is a complete, modular voltage-to-current converter providing the user with a convenient way to produce a current output signal which is proportional to the voltage input. The nominal input voltage range is 0 to +10V. The output current range is 4 to 20mA into a grounded load. Featuring low drift (0.005%/°C max, 2B20B) over the -25°C to +85°C temperature range and single supply operation (+10V to +32V), model 2B20 is available in two accuracy grades. The 2B20B offers precision performance with nonlinearity error of 0.005% (max) and guaranteed low offset error of ±0.1% max and span error of ±0.2% max, without external trims. The 2B20A is an economical solution for applications with lesser accuracy requirements, featuring nonlinearity error of 0.025% (max), offset error of ±0.4% (max), span error of ±0.6% (max), and span stability of 0.01%/°C max. The 2B20 is contained in a small (1.1" x 1.1" x 0.4"), rugged, epoxy encapsulated package. For maximum versatility, two signal input (VIN1 and VIN2) and two reference input (REFIN1 and REFIN2) terminals are provided. Utilizing terminals VIN1 and REFIN1 eliminates the need for any external components, since offset and span are internally calibrated. If higher accuracy (up to ±0.01%) is required, inputs VIN2 and REFIN2 with series trim potentiometers may be utilized.

2B22 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.

2B23 General Description

The model 2B23 is a high performance, low cost voltage to current converter featuring ±1500V pk input to output isolation for interfacing with standard process signals. The input stage of the 2B23 may be single resistor programmed to accept voltages within a 0 to +10V range (+0.1V to +10V full scale). The isolated output is pin programmable to provide current in the range of 4 to 20mA or 0 to 20mA and can be operated with 0 to 800W grounded or floating loads.

The 2B23 uses reliable transformer isolation techniques and is available in two accuracy selections offering guaranteed non-linearity error (2B23K: ± 0.05% max, 2B23J: ± 0.1% max) and guaranteed low span drift (2B23K: ±0.005%/°C max, 2B23J: ±0.01%/°C max). The internally trimmed span and offset errors are ±0.1% for the 2B23K and ±0.25% for the 2B23J. Both span and offset may be adjusted using optional external potentiometers.

Featuring wide range, single supply operation (+14V to + 28V dc), the 2B23 provides isolated loop power, thus eliminating the need for an external dc/dc converter.
