BENTLY 3500/32 is a 4-channel relay module mainly used for mechanical status monitoring and protection systems in industrial automation. The following is a detailed analysis of it:

Basic parameters and specifications

Model: BENTLY 3500/32

Type: 4-channel relay module

Function: Provides four relay outputs and highly configurable relay logic interfaces for mechanical status monitoring and protection.

Relay type: Two single pole double throw (SPDT) relays connected together to form a double pole double throw (DPDT) form.

Work environment:

Working temperature: -30 ° C to+65 ° C

Storage temperature: -40 ° C to+85 ° C

Humidity: 95%, non condensing

Functional characteristics

High configurability: Each of the four outputs can be independently programmed to enable voting by configuring alarm drive logic for each relay.

Alarm driven logic: programmed using AND and OR logic, can use any combination of alarm inputs (warning or danger) from any monitoring channel or monitoring channel in the rack.

Easy to use: Provides an easy-to-use interface for highly configurable AND/OR logic combinations, including “normal” and “true” and voting options, as well as blocking relay channel options.

Widely used: widely used in fields such as power generation, chemical industry, petroleum, water treatment, etc., for monitoring and protecting critical equipment.

Technical specifications

Input power consumption: generally 6 watts

LED indication:

OK LED: Flashes when the module is working properly

TX/RX LED: used for transmission and reception, flashing when the communication between this module and other modules in the frame is normal

CH Alarm LED: Flashes when the relay channel is in an alarm state

Contact life: 100000 times @ 5A, 24Vdc or 120Vdc

Arc extinguishing condition: 250Vrms
