1. 繼電器輸入：該模塊通常配備多個繼電器輸入通道，用于接收外部信號。這些信號可以來自傳感器、開關(guān)、按鈕等設(shè)備。

2. 輸入類型：繼電器輸入模塊通常支持多種輸入類型，例如數(shù)字輸入（開關(guān)量輸入）和模擬輸入（電壓或電流輸入），以適應(yīng)不同的控制需求。

3. 冗余性：為了確保系統(tǒng)的可靠性，某些模塊可能具備冗余輸入通道，以便在一個輸入通道出現(xiàn)故障時，可以切換到備用輸入通道。

4. 隔離：繼電器輸入模塊通常具有輸入通道之間的隔離，以防止干擾和故障傳播。

5. 編程和配置：該模塊通常支持可編程的配置和設(shè)置，用戶可以根據(jù)實際需求進行設(shè)置和參數(shù)調(diào)整。

6. 通信接口：繼電器輸入模塊通常具有通信接口，可以與其他設(shè)備或控制系統(tǒng)進行數(shù)據(jù)交換和通訊。

7. 環(huán)境適應(yīng)性：繼電器輸入模塊通常需要適應(yīng)工業(yè)環(huán)境的惡劣條件，包括高溫、濕度、塵埃等。

Relay Input: This module is typically equipped with multiple relay input channels for receiving external signals. These signals can come from devices such as sensors, switches, buttons, etc.

Input Types: Relay input modules typically support multiple input types, such as digital inputs (switching inputs) and analog inputs (voltage or current inputs), to adapt to different control requirements.

Redundancy: To ensure the reliability of the system, certain modules may have redundant input channels so that they can switch to a backup input channel in the event of a failure in one input channel.

Isolation: Relay input modules typically have isolation between input channels to prevent interference and fault propagation.

Programming and configuration: This module usually supports programmable configuration and settings, and users can make settings and parameter adjustments according to actual needs.

Communication interface: Relay input modules typically have communication interfaces that allow for data exchange and communication with other devices or control systems.

Environmental adaptability: Relay input modules usually need to adapt to harsh conditions in industrial environments, including high temperature, humidity, dust, etc.
