Description
Honeywell CC-TUIO31
Technical Specifications 32 signal termination channels; built-in 250 ohm HART matching resistors configurable by jumper; TVS surge suppression per channel; screw-type field terminal blocks; operating temperature -40 ℃ to +70 ℃; mating connector for CC-PUIO31 electronic card.
Functional Features Concentrates multi-core field instrument wiring; provides jumper selection for current or voltage signal mode; suppresses transient surge from field wiring; channel LED indicates wire fault status; separates field wiring side and electronic module side.
Application Scenarios Field signal marshalling for 4-20mA transmitters, solenoid valves, limit switches and pulse sensors in Experion PKS DCS cabinets.
Material Composition Flame-retardant glass fiber panel; FR4 signal conditioning PCB; TVS surge protection components; high-density screw terminals; gold-plated connectors for electronic module.
Structural Characteristics Rack-mounted termination board; front side has dense screw terminals for field cable access; rear connector accepts CC-PUIO31 electronic module; jumper pins for signal mode configuration.
Working Principle Field cables connect to screw terminals on the front side. Signals pass through surge suppression circuits and optional HART resistors, then transfer to CC-PUIO31 electronic module via rear connector. The module routes signal to analog or digital circuit according to jumper setting.
Installation Requirements Mount in standard Honeywell control cabinet rack; tighten all field terminal screws to prevent high contact resistance; configure jumpers according to signal type drawing; shield layer of instrument cable connects to cabinet ground bar.
Operation Notes Do not change jumper setting while field instrument is powered; isolate loop power before removing field wiring; inspect terminal tightness after long-term vibration operation.
