SMART Transmitter Power Supply Model HiC2025 is for the supply of intrinsically safe transmitters located in an explosive atmosphere and can also be used with an active intrinsically safe current source. It transfers the analog input signal to the non-intrinsically safe side as an isolated current signal.Bi-directional communication is supported for transmitters that use current modulation to transmit data and voltage modulation to receive data.SMART Current Driver Model HiC2031 repeats a 4 - 20 mA input signal from a non-intrinsically safe source to drive intrinsically safe HART I/P converters, valve actuators, and displays located in an explosive atmosphere.The modules mount into a HiC Termination Board.Ambient temperature range -20 ºC to +60 ºC.
The modules shall be installed in an enclosure or cabinet that at least is in compliance with the requirements of the standards listed and that provides a degree of protection of at least IP54.Provision shall be made externally to provide transient protection, set at a level not exceeding a peak voltage of 119 V.The modules may only be disconnected from or connected to the HiC Termination Board if the system is de-energized or if no explosive atmosphere is present.The use of operating elements is only allowed if if the system is de-energized or if no explosive atmosphere is present.
Electrical dataModel HiC2025Supply:19 ... 30 V (via Termination Board),rated current maximum 45 mA,power maximum 1.1 W.Output:4 ... 20 mA or 1 ... 5 V on maximum 300 Ω (source mode) or4 ... 20 mA, 15 … 26 Vdc (sink mode).Model HiC2031Supply:19 ... 30 V (via Termination Board),rated current maximum 30 mA,power maximum 700 mW.Input:4 ... 20 mA (max. 30 mA),maximum 27 V.For data of the intrinsically safe input, respectively output circuits, refer to Certificate of ConformityIECEx CES 06.0002.
