Dwyer SC4130-4151-4380 series

The SC4380 Process Signal Converter/Isolator accepts virtually all standard process signals as input, and isolates and retransmits the signal in either the same units or virtually any other standard process signal. The SC4380 can be field programmed for reverse or direct action and can receive and transmit single sided or bipolar* signals. Low voltage units (SCL) are also available.

The SC4151 RTD Transmitters each offer a fixed scale range input (selected when ordered) and a linearized, isolated, field selectable 4 to 20 mA or 0 to 10 VDC output. Output is selected by simple switch settings. Low voltage units (SCL) are also available.

SC4130 Thermocouple Transmitter offers a fixed scale range input (selected when ordered) and a linearized, isolated, field selectable 4 to 20 mA or 0 to 10 VDC output. Output is selected by simple switch settings. Low voltage units (SCL) are also available.

*Note: The term “bipolar” refers to an input or output that crosses zero volts. Certain devices have ranges that run from minus to plus voltages ( e.g. -1 to +5 VDC, -10 to +10 VDC, etc.). The SC4380 Iso Verter® II can be set up to accept bipolar signal input or provide bipolar output.

• Signal conditioners used in panels for isolation and converting signals for boilers and control systems.
