The 1746sc-INO4I is an analog current-only 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 a current of 120 milliamperes at 5 Volts DC from the backplane, but to minimize the current load on the backplane, the 1746sc-INO4I can be interfaced with an external power source with a voltage rating of 24 Volts DC. The 1746sc-INO4I has a DIP switch to specify whether the module draws power from the backplane or an external power source. When the DIP switch on the 1746sc-INO4I is set to the RACK position, the module draws power from the backplane while the module is powered from an external 24 Volts DC power 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 same when the module is powered externally. The module has a removable 16-position terminal block which accommodates a Belden 8761 shielded twisted pair cable. The 1746sc-INO4I has a resolution of 16 bits, a current of 366 Nano-Amps per count, and a voltage of 320 microvolts per count. The 1746sc-INO4I isolated-channel analog output model has auto-calibration programmable limits and safe states, an optoelectrical isolation of 750 Volts DC (channel-to-channel and field-wiring-to-backplane). The thermal dissipation rating for the 1746sc-INO4I stands at a maximum of 4.5 watts, a maximum update time of 33.7 milliseconds for all the 4 channels in parallel, and a step response time of 1 millisecond. Additionally, the 1746sc-INO4I is UL/CUL class I, division 2, groups A, B, C, D, and CE certified.

The SLC 500 compatible module with part number 1746sc-INO4I is an analog output module that is manufactured by spectrum control. This module is manufactured by AB’s encompass partner Spectrum Controls.

Encompass partners are AB approved and certified partners that provide AB compatible products.

The appearance of this module resembles an actual SLC 500 module. This module features Four (4) differential analog output channels that provides 0-20 mA, 0-21 mA, 4-20 mA in 16-Bit resolution, 366 nA per count. This module features extended output ranges, auto-calibration, programmable limits and safe states. The data of this module is capable of being formatted to 16-Bit Two’s complement, Scaled Engineering Units, Scaled for PID, 1746-NO4 format and user-defined proportional counts. It has an accuracy of 0.08% of full scale at 25 Deg. Celsius and 0.15% at 60 Deg. Celsius.

This module features Increased system reliability by each channel is provided with 750 VDC isolation, eliminating noise ross talk which results to the module’s high resolution data conversion. The same isolation rating is provided for field-wiring to backplane for rack and processor protection.

This module reduces system cost as the module’s isolation eliminates the use of external signal isolating devices. The single slot width of this module also saves important chassis slot.

This module incorporates Allen-Bradly design and technology which allows it to function similarly like an AB module. It is configured similarly to an SLC 500 module with most features also similar to an AB analog output module.
