The 1746sc-INO4I draws 5 volts DC from the backplane. This consumption rating is the same when the module is powered externally. The module has a removable 16-bit terminal block that accommodates Belden 8761 shielded twisted-pair cable. 1746sc-INO4I has 16-bit resolution, 366 nano-amps per count, and 320 microvolts per count. 1746sc-INO4I isolated channel analogue output models have auto-calibrating programmable limits and safety states, and are optically isolated for The 1746sc-INO4I isolated channel analogue output model has auto-calibrated programmable limits and safety states, and is opto-isolated to 750 volts DC (channel-to-channel, field wiring to backplane). 1746sc-INO4I is rated for thermal power dissipation up to 4.5 watts, with a maximum update time of 33.7 milliseconds for all 4 parallel channels, and a step response time of 1 millisecond. In addition, the 1746sc-INO4I is UL/CUL Class I, Division 2. Groups A, B, C, D, and CE listed.

Part number 1746sc-INO4I SLC 500 compatible module dcs-sis.com is an analogue output module manufactured by spectrum control. This module is manufactured by Spectrum Controls, an Allen-Bradley partner.

Encompass Partners is an Allen-Bradley approved and certified partner to provide Allen-Bradley compatible products.

This module is similar in appearance to the actual SLC 500 module. The module has four (4) differential analogue output channels providing 0-20 mA, 0-21 mA, 4-20 mA at 366 nA per count with 16-bit resolution.The module features extended output ranges, auto-calibration, programmable limits, and safety status. The module’s data can be formatted into 16-bit binary, scaled engineering units, PID scaling, 1746-NO4 format, and user-defined proportional counts. Its accuracy is 0.08 per cent of full scale at 25 degrees Celsius and 0.15 per cent at 60 degrees Celsius.

Each channel of the module is galvanically isolated at 750 VDC, which improves system reliability by eliminating the noise crosstalk that occurs when converting the module’s high-resolution data. The same isolation level as the backplane field wiring provides protection for the rack and processor.

Since the module’s isolation eliminates the need for external signal isolation devices, system costs are reduced. The module’s single-slot width also saves critical chassis slots.

The module uses Allen-Bradley design and technology and functions like an Allen-Bradley module. Its configuration is similar to the SLC 500 module and most of its features are similar to the Allen-Bradley analogue output modules.
