TRICONEX 3721 Power Supply High Density Module Invensys

TRICONEX 3721 is a powerful and widely used industrial control module. Here is a detailed introduction:

Basic Information

Series: Triconex series, designed for industrial automation and safety-critical applications.

Type: Digital input card for TRICONEX Trident Safety Instrumented System (SIS).

Specifications

Digital input: 16 channels, individually configurable.

Input type: contact closure, voltage signal or current signal.

Input range: 0-30VDC or 0-24mA (sink or source current).

Input filter: programmable from 0 to 1 second.

Input debounce time: programmable from 0 to 500 milliseconds.

Input voltage isolation: 1500Vrms between field side and logic side.

Input current isolation: 3000Vrms between field side and logic side.

Hot swap: supported, can be replaced without interrupting the operation of the Triconex system.

Operating temperature: -40°C to +70°C.

Shock and vibration: Tested to IEC 60068-2.

Power consumption: 4 watts maximum.

Compatibility: Triconex Trident safety instrumented system.

Features

High reliability: Triple redundant (TMR) design allows the system to operate normally even if a single module fails. Hot-swap function allows replacement while the system is running, reducing maintenance downtime.

High accuracy: Supports multiple input types with an accuracy of up to 0.1% FS, which can accurately monitor digital signals.

Flexibility: 16 channels can be configured individually, and users can set parameters such as input type, filter, debounce time, etc. according to specific applications.

Strong anti-interference ability: Differential inputs suppress common-mode interference, ensure accurate data transmission, and can work stably in harsh industrial environments.

Ease of use: Can be configured using Triconex's TriStation 1131 software, which has a user-friendly interface and is easy to operate.

Application areas

Oil and gas: used for process monitoring, safety interlocking and emergency shutdown systems, reliable monitoring of digital signals, and ensuring safe operation.

Renewable energy: such as wind power generation, solar photovoltaic systems and energy storage systems, which can accurately monitor and control the digital signals of related equipment.
