The TXHX13‑ZW20DX1 is a high‑speed carrier communication single‑phase module with OFDM modulation, 0.7‑12 MHz carrier range, up to 10 Mbps data rate, and…
The TXHX13‑ZW20DX1 module is designed for smart‑grid electricity information collection systems, providing high‑performance, low‑power carrier communication for single‑phase smart meters. It interfaces with concentrator modules to deliver meter data, tariff updates, event reporting, and remote firmware upgrades.
Key technical features include OFDM signal modulation, four selectable working bands (0.7‑2.93 MHz, 2.441‑5.615 MHz, 1.758‑2.93 MHz, 1.953‑11.96 MHz), communication rates from 55 kbps to 10 Mbps, and a CSMA/CA access mechanism. The module operates from –40 °C to +70 °C, consumes ≤1.5 W dynamic and ≤0.4 W static power, and can communicate up to 200 m (500 m max) over power‑line channels. This manual is written in Chinese.
| Signal modulation method | OFDM |
|---|---|
| Carrier frequency range | 0.7‑12 MHz |
| Communication rate | 55 kbps–10 Mbps |
| Power spectral density (in‑band) | ≤‑45 dBm/Hz |
| Communication distance (typical) | up to 200 m |
| Communication distance (maximum) | up to 500 m |
| Dynamic power consumption | ≤1.5 W |
| Static power consumption | ≤0.4 W |
| Operating temperature range | -40 °C to +70 °C |
| Input power requirement | 12 V DC ± 1 V, load ≥125 mA, ripple Vp‑p <1‰ |
It supports the DL/T645‑1997/2007 multi‑function meter communication protocol and the DL/T698.45 data exchange protocol.
The module requires a 12 V DC supply with ±1 V tolerance, a load of at least 125 mA, and the supply ripple must be less than 1‰ peak‑to‑peak.
Under normal conditions the module can communicate up to 200 m, and up to 500 m under optimal conditions.
It can operate from –40 °C to +70 °C.
