JUUKO HS3604 ID:11003B33 Digital Input Module

Overview

The JUUKO HS3604 ID:11003B33 is a 4-channel digital input module for JUUKO distributed control systems. The JUUKO HS3604 ID:11003B33 collects discrete on-off signals from field sensors, limit switches and auxiliary contacts, and transmits these status data to the DCS master controller via the internal backplane bus. It supports signal filtering and channel status diagnosis, and is commonly stocked as spare hardware for industrial automation cabinet maintenance and replacement.

Features

The JUUKO HS3604 ID:11003B33 provides 4 independent digital input channels with reverse polarity protection and surge suppression. It supports configurable input debounce time to eliminate signal jitter from mechanical switches. The JUUKO HS3604 ID:11003B33 is equipped with LED indicators for each channel to quickly show signal state and fault condition. It follows the JUUKO bus protocol and hot-swap design, allowing module replacement without shutting down the whole DCS rack. The JUUKO HS3604 ID:11003B33 uses standard rack mounting and consistent pin definition for direct plug-in replacement.

Specs

Device Type: 4-channel digital input module Model: JUUKO HS3604 ID:11003B33 Channel Count: 4 digital input channels Input Type: Dry contact or 24VDC logic input Diagnosis: Per-channel LED status indication Bus Interface: JUUKO DCS internal backplane bus Mounting: Rack slot installation Protection Grade: IP20 Application: DCS system, industrial process signal acquisition, safety interlock signal input

Principle

The JUUKO HS3604 ID:11003B33 scans each input channel cyclically to read the on/off state of field devices. After filtering unstable signals, the module packs the channel status into bus data frames and sends them to the DCS main controller. The module continuously monitors channel circuit integrity. If short circuit or abnormal voltage is detected, the JUUKO HS3604 ID:11003B33 marks the corresponding channel fault and uploads alarm information to the host system.

Applications

The JUUKO HS3604 ID:11003B33 is used for collecting valve feedback, motor auxiliary contact and alarm switch signals in chemical and power plant DCS control systems. It serves interlock condition signal acquisition for process skid and boiler auxiliary control loops. The JUUKO HS3604 ID:11003B33 applies to spare stock and emergency repair of existing JUUKO DCS racks. It also supports new DCS cabinet assembly and I/O expansion projects.
