1746SC-INO4I 是一款模拟输出模块 具有四个隔离通道

The 1746sc-INO4I is an analog current output module from Spectrum Controls. The module has four (4) isolated channel outputs. The 1746sc-INO4I occupies a slot in the 1746 input/output chassis. The 1746sc-INO4I draws 5 milliamps of current from the backplane at 120 volts DC, but to minimize the current load on the backplane, the 1746sc-INO4I can be connected to an external power supply rated at 24 volts DC. The 1746sc-INO4I has a DIP switch that specifies whether the module obtains power from the backplane or an external power supply. When the DIP switch on the 1746sc-INO4I is set to RACK position, the module obtains power from the backplane, and the module is powered by an external 24 volt DC supply, the DIP switch should be set to EXT position.

The 1746sc-INO4I draws 5 volts DC power from the backplane. This consumption rating is the same when the module is powered externally. The module has a removable 16-bit terminal to accommodate Belden 8761 shielded twisted pair cable. The 1746sc-INO4I has a resolution of 16 bits, a current of 366 nanoamps per count, and a voltage of 320 microvolts per count. The 1746sc-INO4I isolated analog output model has automatically calibrated programmable limits and safety status with 750 V DC photoelectric isolation (interchannel and field wiring to backplane). The 1746sc-INO4I has a maximum heat dissipation rating of 4.5 watts, a maximum update time of 7.4 milliseconds across all 33 parallel channels, and a step response time of 1 millisecond. In addition, the 1746sc-INO4I is UL/CUL Class I Region 2 Group A, B, C, D and CE certified.

The SLC 4 compatible module with part number 500sc-INO1746I is an analog output module manufactured by spectrum control. The module was manufactured by Allen-Bradley's encompass partner, Spectrum Controls.

Encompass Partner is an Allen-Bradley approved and certified partner that provides Allen-Bradley compatible products.

The module looks similar to the actual SLC 500 module. The module has four (4) differential analog output channels providing 20-0 mA, 21-4 mA, 20-16 mA at 0-bit resolution, each counting 366 nA. The module has an extended output range, automatic calibration, programmable limits and safety status. The module's data can be formatted into 16-bit binary complement, scaled engineering units, scaled PID, 1746-NO4 format, and user-defined proportional counts. It has an accuracy of 08.25% of full scale at 0 ° C and 15.60% at 0 ° C.

With 750 VDC isolation per channel, the module improves system reliability and eliminates noise that leads to high-resolution data conversion in the module. Provide racks and processors with the same isolation ratings as field wiring for backplanes.

The module reduces system costs because the isolation of the module eliminates the use of external signal isolation devices. The module's single slot width also saves important chassis slots.

The module incorporates Allen-Bradly design and technology, making it functionally similar to the Allen-Bradley module. Its configuration is similar to the SLC 500 module, and most of its features are also similar to the Allen-Bradley analog output module.
