1. Product Overview

2. Core Parameters

3. Product Features

• High Reliability and Industrial-Grade Design: Adopts durable materials and strict industrial standard design to adapt to harsh industrial environments (such as high temperature, humidity, and dust).
• Flexible Logic Programming: Supports AND and OR logic combinations. Users can set complex “Voting Logic”, such as “If both the amplitude and frequency of Sensor A are abnormal, trigger an alarm”.
• Deep Integration: Seamlessly integrates into the BENTLY NEVADA 3500 system architecture, and cooperates with the 3500/93 display module or 3500/94 VGA module to realize graphical parameter display and alarm management.
• Fast Response: The relay output has an extremely short response time, ensuring that key equipment can be powered off or stopped at the initial stage of a fault to prevent the fault from expanding.

4. Structure and Composition

• Relay Output Channels: Usually includes 16 independent channels, each of which can be independently programmed and controlled.
• Indicator Lights: An LED indicator light may be provided next to each channel to display the current on-off status of the relay.
• Communication Interface: Communicates with the host or display through the 3500 system internal bus (such as 3500/11, 3500/12 and other communication modules).
• Backplane Installation: Usually designed for 19-inch rack-mounted installation, inserted into the 3500 system backplane.

6. Installation and Maintenance Recommendations

Installation Environment

• It is recommended to install in a dry environment without corrosive gases, avoiding direct exposure to rain or oil pollution.
• The installation location should be convenient for wiring, and parallel laying with high-power motor cables should be avoided to reduce electromagnetic interference.

Wiring Specifications

• Power Supply: Ensure the power supply voltage is 24VDC, and the current capacity is sufficient to drive all relay coils.
• Load: The rated current and voltage of the relay contacts should be within their bearing range to avoid overload.
• Signal Cables: Correctly connect the alarm output cables (Alarm Output) or input cables (Alarm Input) of the 3500 system to the corresponding ports of the module.
