GE TIS600‑128‑RED‑GE Digital Input Interface Module

Technical Specifications Digital Input Channel Quantity: 128 channels Input Signal Type: Dry‑contact / wet‑contact configurable Input Rated Voltage: 24‑125 VDC Input Impedance: 4.7kΩ typical value Response Time: ≤4ms per channel Backplane Communication: TIS600 internal system bus Operating Power Supply: 24VDC Operating Temperature: ‑40℃ ~ +70℃ Storage Temperature: ‑50℃ ~ +85℃ Relative Humidity: 5%‑95%, non‑condensing Mounting Form: Plug‑in slot installation for TIS600 series rack Certifications: CE, UL industrial control compliance

Functional Features High‑density 128‑channel discrete digital signal acquisition capability. Support dry‑contact and wet‑contact field signal input configuration. Red LED status indicator lamps on front panel for each channel status display. Built‑in hardware filter to suppress field electromagnetic interference signal. Comprehensive channel self‑diagnosis for open‑circuit and abnormal input detection. Real‑time status data upload to main controller via backplane bus. Support hot‑swap operation under system running status.

Application Scenarios Large‑scale petrochemical plant interlock system discrete signal acquisition. Power plant auxiliary equipment status centralized monitoring system. Industrial process safety interlock input signal collection. Manufacturing factory mass‑limit‑switch and sensor status monitoring. TIS600 control system expansion for discrete I/O capacity upgrade.

Structural Characteristics Standard single‑slot plug‑in module housing for TIS600 series rack. Front‑panel array of red LED indicator lamps corresponding to each input channel. Front‑side field signal terminal block for field wiring connection and maintenance. Back‑plane golden‑finger connector for internal system bus communication.

Working Principle Field discrete contact signals access front‑side terminal block. Hardware filter circuit filters high‑frequency interference noise. Signal conditioning circuit converts field contact state into digital logic level. On‑board logic chip collects all channel status data, transmits processed data to main controller through back‑plane bus

Installation Requirements Insert module into designated slot of TIS600 series standard rack. Guarantee rack protective grounding strictly according to system grounding specification. Field signal wiring adopts shielded twisted‑pair cables, separate routing from high‑power power cables.
