SPDSI13 ABB Digital input module High densityhigh reliability compatibility multiple control systems

Product Overview

The ABB SPDSI13 is a high-performance 16-channel digital input module specifically designed for the ABB Freelance DCS system and is an important component of the S800 I/O series. This module supports dry contact and wet node signal input and is widely used in industrial automation scenarios such as power, chemical, water treatment, metallurgy and manufacturing where system stability and response speed are strictly required.

The SPDSI13 adopts a modular design and is used in conjunction with dedicated terminal units. It supports quick plugging and unplugging as well as on-site maintenance, significantly enhancing the efficiency of engineering deployment and system availability.

Core features

16 independent digital input channels, high-density design saves cabinet space
Supports dry contact or wet node signal input, and is compatible with 24VDC or 120/230VAC input
Electrical isolation: Each input channel is electrically isolated from the system bus, providing strong anti-interference capability
Fast response time: < 2 ms (typical value), meeting the requirements of high-speed control
Clear status indication: The panel is equipped with dual groups of leds (each group has 8 channels), which can display the input status in real time
Plug-and-play design: With a dedicated terminal base, it supports hot-swapping of modules (system support required)
DIN rail mounting, compatible with standard control cabinet layout
Powered by the I/O bus, no additional external power supply is required
Seamlessly integrated into Freelance DCS and other compatible control systems
