Description
Features:
This product series comprises a relay module controlled via an industrial RS485 interface. The number of relays can be 8, 16, or 32, utilizing the Modbus RTU protocol, with integrated power isolation, ADI magnetic coupling isolation, self-recovery backup, and TVS protection circuitry. It features an ABS DIN rail enclosure. This product is easy to use, characterized by fast communication speed, stability, reliability, and safety, and can be applied to various industrial control devices or applications with high communication requirements.
Supports device address setting (1-255) for cascading multiple devices via the RS485 bus, with flash-on/flash-off functions. The integrated current isolation can be automatically closed by instructing the relay to remain open for a specified period, providing a stable isolation voltage. No additional power supply is required at the isolation end. The integrated ADI magnetic coupling isolation enables signal isolation with high reliability, strong interference suppression, and low power consumption.
Integrated self-recovery protection and TVS (transient voltage suppressor) effectively suppress surge voltages and transient peak voltages in the circuit, preventing overcurrent and overvoltage, lightning protection and onboard antistatic optical isolation, and preventing relay highs and interference in the voltage circuit.
Using a special relay drive chip, integrated freewheeling diode protection, stronger and more stable drive capability, integrated anti-reverse connection circuit to prevent reverse connection of positive and negative poles and burning out the circuit.
Use of high-quality relays that allow access to loads: ≤10A 250VAC or ≤10A 30V DC, rail-mounted ABS protective housing, easy to install and use, safer with a housing
There are 3 external LED indicators for easy display of the MCU status and the signal transceiver status. Only the 32-channel version has an integrated voltage regulator chip and supports a wide voltage supply from 7 to 36 V.
