Description
Emerson 1C31197G05
Technical Specifications: Rated supply voltage: 24 VDC Isolation rating: 1500 VAC Operating temperature: 0 ℃ to 60 ℃ Storage temperature: -40 ℃ to 85 ℃ Relative humidity: 5% to 95% non-condensing
Functional Features: Multi-channel screw terminals for field cable connection. Built-in transient voltage suppression components absorb voltage spikes from field wiring. Low-pass filter reduces high-frequency noise interference. LED power indicator reflects module operating status. Reserved test points support on-site signal measurement without cable removal. Mechanical anti-misplug structure prevents wrong card installation. It supports hot swap of matched Ovation I/O cards.
Application Scenarios: Petrochemical process parameter monitoring, thermal power plant turbine auxiliary control, municipal water treatment automatic control, cement production line monitoring, pulp and paper factory process control, metallurgy continuous production signal collection.
Performance Parameters: Terminal contact resistance: less than 10 milliohm Signal bandwidth: DC to 10 kHz Vibration withstand: 10 Hz to 150 Hz, 0.5g Shock withstand: 10g peak, 11ms MTBF: 204000 hours
Material Composition: Housing material: UL94-V0 flame retardant thermoplastic. Terminal hardware: nickel-plated brass. Circuit board substrate: FR4 epoxy glass fiber board. Surge protection components encapsulated by epoxy resin. DIN rail fixing spring clip: stainless steel.
Structural Features: 35mm DIN rail snap buckle installation. Front panel arranges screw terminals and channel marking area. Top card socket is reserved for I/O card plugging. Positioning buckle ensures accurate alignment with matched I/O hardware. Dust-proof grooves are molded on shell surface to reduce dust accumulation. Ventilation slots provide passive heat dissipation.
Working Principle: Signals coming from field instruments connect to front screw terminals. Signals go through built-in surge protection circuit and EMI filter circuit, then transfer to I/O card mounted on the top socket. The I/O card converts analog or digital signals into digital data and transmits data to Ovation controller. The terminal base distributes 24V DC power for field signal loops.
Installation Requirements: Install on standard 35mm DIN rail inside control cabinet. Reserve 20mm vertical ventilation space. Route field instrument cables and high voltage power cables separately. Terminal screw tightening torque ranges from 0.6 N·m to 0.8 N·m. Complete power-off operation before wiring work.
Precautions for Use: Do not install in environments with corrosive vapor, conductive dust or heavy oil mist. Anti-static wristband must be worn when maintaining internal circuits. Check terminal screw tightness periodically. Disconnect all field wiring before removing the terminal base from DIN rail.
