Description
Emerson 1C31238H01
Technical Specifications: Nominal supply voltage:24 VDC Insulation voltage:1500 VAC Operating temperature:0 ℃ ~60 ℃ Storage temperature:-40 ℃ ~85 ℃ Humidity:5% ~95% non-condensing
Functional Features: Multi-channel screw wiring terminals. Built-in surge suppression circuit. EMI filter eliminates high-frequency electromagnetic noise. LED power working indicator. Reserved signal test jacks for maintenance measurement. DIN rail snap mounting. Mechanical anti-mismatch structure. Support hot swap of matched I/O cards.
Application Scenarios: Power plant boiler auxiliary monitoring, petrochemical refining process control, metallurgical equipment interlock control, paper mill production line control, municipal sewage automatic control.
Performance Parameters: Terminal contact resistance less than 10 milliohm Vibration resistance:10 Hz~150 Hz,0.5g Shock resistance:10g peak,11ms MTBF:207000 hours
Material Composition: Shell: UL94-V0 flame retardant plastic. Terminal screws: nickel-plated brass. PCB substrate: FR4 epoxy glass fiber board. Electronic protection components soldered on PCB. Mounting spring clip: stainless steel.
Structural Features: 35mm DIN rail snap buckle structure. Front panel arranged with screw terminals and channel label printing. Top card socket for I/O card plugging. Anti-misplug positioning buckle. Dust-proof grooves on housing surface.
Working Principle: Field sensor and actuator signals connect to front wiring terminals. Signals go through surge protection and filter circuits, then transmit to I/O card mounted on the base. I/O card converts analog or discrete signals into digital data and transmits data to Ovation controller. The terminal unit distributes DC power supply for field signal loops.
Installation Requirements: Mount on standard 35mm DIN rail. Reserve 25mm vertical heat dissipation space. Separate analog signal cables and high voltage power cables. Terminal screw torque 0.6~0.8 N·m. Cut off relevant power supply before wiring.
Precautions for Use: Do not install in environment with corrosive vapor or conductive dust. Anti-static wristband required for maintenance work. Regularly inspect terminal screw tightness. Stop using the terminal unit if shell cracks or burn marks appear.
