The Crompton Instruments 256-TWMU Transmitter Module accepts a 4–20 mA signal and presents a 500 Ω burden, intended for use in 60 Hz three-phase, three-wire electrical systems. It provides a fixed current-loop interface suitable for standard instrumentation networks that require a defined burden in a 3‑phase configuration. Key specifications include a 4–20 mA input range and a 500 Ω burden, compatible with 60 Hz 3‑phase installations.
