TRI-SEN DI3201E module

Product Overview:

TRI-SEN DI3201E is a 32 channel digital input module designed specifically for distribution automation terminals and industrial sites.

It supports AC/DC wide voltage input, with 3500 V insulation isolation and low leakage current design,

It can directly access circuit breaker status, contactor feedback, button or sensor dry contact signals, and upload data in real-time to PLC, RTU or SCADA systems with high anti-interference ability.

Main features and advantages

Wide voltage input: Each channel can accept 165-265 V AC or 110-220 V DC dry contact signals, compatible with various on-site switch power supplies and battery packs.

High isolation withstand voltage: Input output logic three terminal withstand voltage of 3500 V AC, leakage current ≤ 5 mA, insulation impedance ≥ 100 M Ω, can work stably in strong electromagnetic interference environment for a long time.

High density channel: 32 optoelectronic isolated inputs, only one module is needed to cover the state data acquisition of the entire distribution cabinet, saving cabinet space.

Modular hot swappable: DIN rail installation, supports live plugging, maintenance without power outage, shortens downtime.

Intelligent diagnosis: The onboard LED indicates each channel, and with the help of the upper computer, it can read information on wire breakage, short circuit, and power failure, making it easy to quickly locate.
