Technical Specifications Output Signal Type: Discrete digital output Rated Output Voltage: Isolated relay output type Channel Quantity: 16 output channels Field‑to‑Backplane Isolation: High‑voltage electrical isolation for each group Backplane Interface: Series 90‑70 backplane bus Operating Power: Supplied through 90‑70 rack backplane Operating Temperature: ‑40 ℃ to +70 ℃ Storage Temperature: ‑50 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Single‑slot module for GE 90‑70 rack Certifications: CE, UL industrial control compliance
Functional Features 16‑channel relay‑type discrete output to drive field on‑off actuators. Group‑wise electrical isolation separates internal system circuit and field load side. Front‑panel LED status lamps show on‑off state of each output channel. Receives output command from 90‑70 CPU via backplane bus and drives field loads. Built‑in hardware diagnosis for channel abnormal status feedback to main controller.
Application Scenarios Field actuator driving for chemical and process‑control automation system. Solenoid valve and relay control for manufacturing production line equipment. Switch‑state output for metallurgy and power industry interlock control loops. Legacy GE 90‑70 PLC automation system spare‑part replacement.
Structural Characteristics Standard single‑slot plug‑in structure compatible with GE 90‑70 rack. Front‑panel LED indicator for every output channel status display. Front‑mounted terminal block for field load wiring connection. Backplane golden‑finger interface for command data and power supply access. Locking mechanism for firm installation inside rack against vibration displacement.
Working Principle Main CPU transmits logic output commands to this module via rack backplane bus. Internal circuit drives corresponding relay contact action according to command signal, so as to switch on or off field load circuit.
Installation Requirements Install module into suitable slot of GE Series 90‑70 standard rack. Ensure rack protective grounding strictly follows official grounding specification. Field load wiring shall select proper wire gauge matching load current.
