Description
The ABB 23WT22 Voice Frequency Message Device Module is designed to provide stable and clear voice frequency signal transmission in industrial control and monitoring systems. This module supports standard voice frequency ranges from 300Hz to 3.4kHz, enabling efficient conversion between voice and telegraph signals, and is suitable for use in control systems, monitoring terminals, or industrial communication networks. Its integrated reliable signal modulator/demodulator maintains high signal accuracy and interference immunity in complex industrial environments.

The module operates on a standard 24V DC power supply with a power consumption of approximately 10W. Its input/output impedance is designed to be 600Ω, and the output signal level is +4dBm, providing clear and effective voice frequency communication output. The operating temperature range is –10°C to +50°C, and the storage temperature range is –20°C to +70°C, adapting to various industrial field conditions. It also supports non-condensing environments with relative humidity of 5%–95%. The module has an IP20 protection rating, making it suitable for installation within control cabinets or communication enclosures.

The 23WT22 has a wide range of applications and can be used for full-duplex or half-duplex communication, multi-point or point-to-point configuration between industrial data terminal equipment (DTE). It meets the needs of long-distance and stable voice frequency signal transmission in industrial sites and is an important component for providing reliable industrial communication links.
