Mounting Kits
The Model MK 296 and MK 296HP Mounting Kits are for
resistive or voltage programming of the Model 930. The MK
296HP is a high current version with a power transistor to
increase the range to 0.5A. The Model MK 298 allows
adjustment of the “l(fā)ive zero” for 4 to 20 mA systems. All three
mounting kits consist of the PC board, PC connector with
built-in guides, and the necessary potentiometers. When
ordered with the Model 930 the unit will be delivered mounted.
They can be plugged into the 22-100MK Power Source Kit
(page F2) or used with any of the CALEX supplies or DC/DC
Converters.
For the MK 298 the output current can be programmed for
input voltages other than 0 to 10 Volts by changing the value
of RS.
The formula for RS is:
RS = Vin (max)
10
Ι
0 (max)
Where: Vin (max) = max programming (input) voltage
Ι
0 = max output current
Note: +VS must be a regulated (0.1% or better) source, and
be 14 Volts to 24 Volts.
To Calibrate: repeat as necessary
1. With the max Vin adjust the span pot. for max
Ι
out
2. With min Vin adjust the zero pot. for min
