IMPORTANT SAFETY CONSIDERATIONS
You must consider the possible negative effects of power, wiring, component, sensor, or software failure in the design of
any type of control or monitoring system. This is very important where property loss or human life is involved. It is
important that you perform satisfactory overall system design and it is agreed between you and Acromag, that this is your
responsibility.
The information of this manual may change without notice. Acromag makes no warranty of any kind regarding this

to update, or keep current, the information contained in this manual. No part of this manual may be copied or

This manual is for 4-wire (separate isolated power) SP300 transmitters that convert DC voltage and current
signals to dual isolated voltage or current output signals. To split microBlox (uB) module inputs similarly,
please refer to our uBSP-P-1 model. If your application requires dual 2-wire (loop-powered) outputs instead,
please refer to similar SP200 series models. For thermocouple input signals, please refer to our SP333 (4-wire)
and SP233 (2-wire loop-powered) models.
