Acromag - Model TT238 - High Voltage Input, Loop-Powered, 2-Wire Transmitter
From Signal Converters, Transmitters
The TT238 model is a space-saving two-wire transmitter that isolates and converts a high level DC voltage input to a proportional 4-20mA control signal. A single unit supports multiple voltage input ranges for extra flexibility. Power is received from the output loop current or a local DC supply when using a three-wire connection. High-voltage isolation separates the input from the output circuit. Isolation protects from surges, reduces noise, and eliminates ground loop errors.
