Description
Emerson 1C31116G04
Technical Specifications: Operating voltage: 24VDC. Number of signal channels: 16 channels. Isolation voltage: 1500VAC. Operating temperature: 0℃ to 60℃. Storage temperature: -40℃ to 85℃. Humidity range: 5% ~95% non-condensing.
Functional Features: Each channel has independent overvoltage protection circuit. LED indicators display on/off status of each input channel. It supports dry contact and wet contact signal input. It has channel fault detection function. DIN rail installation, convenient for cabinet layout. It can work continuously for long time in industrial cabinet environment.
Application Scenarios: Power plant boiler auxiliary equipment status collection, valve position feedback signal acquisition, pump running status monitoring, chemical plant switch signal collection, metallurgical equipment interlock signal monitoring.
Performance Parameters: Input signal response time: less than 1ms. Contact withstand current: 1A per channel. Vibration: 10~150Hz, 0.5g. Shock: 10g, 11ms. MTBF: 210000 hours.
Material Composition: Base shell: UL94-V0 flame retardant plastic. Terminals: nickel-plated brass. Circuit board: FR4 glass epoxy board. Protection diode and resistance components are soldered on PCB. Fixed spring clip: stainless steel.
Structural Features: Standard DIN rail buckle structure. Front panel has channel LED indicators and printed channel numbers. Upper card slot for digital input card. Screw terminals arranged in two rows on front face. Anti-misplug structure prevents mismatching with other type I/O cards. Dust-proof edge design reduces dust accumulation.
Working Principle: Field dry contact or wet contact switch signal is connected to terminal block. Signal passes through isolation and protection circuit, then transmits to matched digital input card. The card identifies on and off state of contact and sends digital data to Ovation controller. The terminal base provides necessary power supply for wet contact input.
Installation Requirements: Install on 35mm DIN rail. Keep 20mm vertical space for heat dissipation. Separate field signal cable and high voltage power cable. Tighten terminal screw torque between 0.6~0.8 N·m. Cut off power before wiring work. Keep away from high electromagnetic interference equipment.
Precautions for Use: Do not connect high voltage AC signal to digital input terminals. Wear anti-static wristband when touching circuit part. Check terminal tightness during quarterly maintenance. Stop using the module if burning marks appear on the shell. Avoid installation in environment with corrosive gas.
