The ASM-83 uses a 32-bit ARM processor with a clock speed up to 72MHz. Its high-performance hardware architecture ensures powerful data processing capability.

It can provide up to 6 Ethernet ports, 6 CAN ports and 24 serial ports (RS-232/RS-485), to be specified when ordering.

It is equipped with 64KB of non-volatile FRAM (retains data after power failure).

The protocol processing module is highly flexible. It can connect to radio stations, carrier equipment and other devices to support synchronous and asynchronous communication at various baud rates. It supports one or two of the following protocols: ML2000, CDT, 1801, IEC101, N4F, IEC104, IEC103.

Via “intelligent interface modules”, it connects to intelligent devices from other manufacturers, providing standard RS-232, RS-485 ports and corresponding interface protocols.

With a highly reliable design, it ensures stable contact of components and connectors. It is shock and vibration resistant, suitable for strong electromagnetic interference environments, and can operate normally at temperatures from -25℃ to +60℃. Its insulation, voltage withstand and anti-interference performance comply with IEC international standards.

Complete background maintenance software with a clean and friendly interface, supporting parameter configuration, message monitoring and data viewing.

In DC inductive circuits with voltage ≤ 250V, current ≤ 0.5A, time constant 5±0.75ms, the breaking capacity of output contacts is 50W, continuous allowable current ≤ 5A (resistive load).

Access cycles: > 10 billion times

Insulation resistance between power supply and output circuits, measured with a 500V megohmmeter: ≥ 100MΩ.

a) Operating conditions: withstand vibration response and shock response tests at severity Level I.

b) Transportation conditions: withstand vibration endurance, shock endurance and bump tests at severity Level I.

In accordance with GB/T 13729-1992 Clause 3.8, under standard atmospheric conditions, the device can withstand 1MHz±0.1MHz damped oscillatory interference (common mode 2.5kV, normal mode 1kV, repetition rate 400 times/s) applied to the AC power circuit while in normal operation.

The device complies with severity Level III in GB/T 15153.1-1998 Table 13, withstanding 6kV contact discharge.

10 positive and 10 negative discharges are applied to accessible surfaces at intervals ≥1s. Temporary indicator errors are allowed during testing.

In accordance with GB/T 15153.1‑1998 Table 12 severity Level 3, the device can withstand 2.0kV(p) fast transient burst interference. Temporary indicator errors are allowed during testing.

The ASM-83 communication management unit is an important part of substation integrated automation systems, suitable for substations of 110kV and below.

It is mainly used to collect on-site information of the entire power transformation and distribution automation system, transmit data to the local background or remote dispatch master station, and send commands from the background or master station to each measurement and control device to realize local or remote control.

It can complete data exchange with bay-level equipment, protocol conversion, central signal processing and other functions.
