Thermocouple and RTD Single Input 400B and 410B Indicators
The 400B and 410B Series measure temperatures with laboratory accuracy. Signals from thermocouples and RTD’s can be displayed with 1° or 0.1° resolution. High instrument accuracy is achieved with a superior combination of low noise analog-to-digital conversion, multi­segment linearization conformity and isolated electronics. The standard resolution version, the 400B, has a 1° resolution. The higher resolution version, 410B, provides a 0.1° resolution. A miniature “DIP” switch, easily accessible behind the front panel, makes the °C to °F conversion a snap. You can add one option card to either the Model 400B or 410B.

Inputs
Thermocouple Multi-Input 402B and 412B Indicators
The 402B and the 412B have multi-input boards that can switch between five inputs of a common input type (e.g., 5 Type K thermocouples). A row of five pushbutton switches, accessible on the front panel, permits easy switching between sensor readings. There are screw terminals located at the rear of the instrument where up to five sensors can be attached. The 402B has a standard 1° resolution. The 412B has a 0.1° resolution.
DC and Scaled DC 400B and 410B Indicators
For dc voltage single range indicators, the 400B and 410B provide exceptional accuracy and resolution for direct measurement of dc voltages. Ranges from 25 mV to 25 Vdc can be selected and measured with laboratory accuracy and repeatability. The 400B displays the voltage within -1000 to 2500 counts with 1-count accuracy. The 410B provides an additional decade of resolution from -10000 to 25000 and accuracy to 0.01% of reading. Both instruments offer exceptional 1-count repeatability.
For Additional Controllers, See Section P
Scaled dc Voltage and Current Loop Single Input 400B and 410B Indicators
The Models 400B and 410B display process parameters with laboratory accuracy. Signals from current transmitters, signal conditioners or other dc voltage sources can be scaled to display directly in engineering units.
Three types of input/display ranges are available. The I-1 range accepts 4 to 20 mA as its input and automatically scales and displays indicated results as 0.0 to 100% on the 400B (0.00 to 100.00% on the 410B). The decimal point position can be changed via programming, and various engineering unit labels are included. For user scalable, wide ranging displays from 4 to 20 mA inputs, select the I-3 range, or for 0 to 5 V, select the V5 range. Both provide the ability to scale and offset the instrument’s display proportional to process engineering units.

dc Voltage Multi-Input 402B and 412B Indicators
Models 402B and 412B provide low cost measurement in applications where more than one voltage input is needed. Five front panel pushbuttons provide convenient selection between similar inputs. All channels must measure the same input range (e.g., -10 to 25 volts).
Scaled dc Voltage Multi-Input 402B and 412B Indicators
Models 402B and 412B can be specified with the V5 range to provide the ability to switch between five inputs of a commonly scaled voltage (e.g., all inputs accepting 1 to 5 Vdc inputs can be scaled to display 0 to 2500). A row of five pushbutton switches permits easy switching between input readings.
