About the 1746SC-INO4I

The 1746sc-INO4I is Spectrum Controls’ analogue pure current output module. The module has four (4) isolated channel outputs.The 1746sc-INO4I occupies one slot in the 1746 Input/Output Chassis.The 1746sc-INO4I draws 120 milliamps of current from the backplane at 5 volts DC, but in order to minimise current loading on the backplane, the 1746sc-INO4I can be interfaced with an external power supply rated at 24 volts DC. The 1746sc-INO4I has a DIP switch that specifies whether the module is to be powered from the backplane or from an external power supply. When the DIP switch on the 1746sc-INO4I is set to the rack position, the module is powered from the backplane, and when the module is powered from an external 24 Vdc power supply, the DIP switch should be set to the EXT position.

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.
