Transmitter, High Voltage Input, Loop-Powered

• Multi-range ±15V, ±75V or ±150V input

• Universal current/voltage ouput

• 12-32V DC power

The TT338 model is a space-saving four-wire transmitter that isolates and converts a high level DC voltage input to a proportional control signal. DC current and voltage output are both supported on a single model. An optional DIN rail bus can deliver primary or redundant power to multiple units without wiring.

High-voltage isolation separates the input from the output circuit. Isolation protects from surges, reduces noise, and eliminates ground loop errors.
