АИ-701 Высокая производительность Интеллектуальная индикации / ала

Suitable for measuring and displaying temperature, pressure, flow, level, humidity .... etc with measurement accuracy of 0.2% full scale.MAIN FEATURES: ◊ Programmable and modular inputs, multiple input types of thermocouples and RTDs, voltage/current inputs and two-wire transmitters are fieldselectable. ◊ Dual display windows, convenient to set parameters and alarm points. Various dimensions are selectable. ◊ Support up to 4 loops of alarms, or 2 loops of high limit alarms plus 2 loops of low limit alarms. Alarms can be outputted to different relays or one. ◊With functions of digital calibrating, digital filtering, and thermocouple cold junction auto compensating, free of maintenance and easy operated. ◊Support RS485 communication interface, enable to communicate with computers. ◊Retransmission function, cooperating with X3 high precision current output module (0.2%FS), can retransmit temperature with accuracy of 0.3% ◊High quality and performance hardware design, using high performance tantalum capacitor or ceramic capacitor. ◊Universal 100-240V power supply, with thunderbolt proof and 10 seconds protection from connecting to 380VAC by mistake. Model Code Legend The ordering code of AI-701 is made up of 8 parts, for example: AI-701 AI31 X3 L5L1 S4 — 24VDC (1)(2) (3)(4)(5)(6) (7) (8) (1)model AI-701, Indicating/Alarming Instrument with measurement accuracy of 0.2%FS (2)shows the dimension: SIZEFront PanelCut-out DimensionDepth BehindRemarkW*HW*HMountingA/A296*96MM92*92MM100MMA2 is intelligent light bar panelB160*80MM152*76MM100MMC/C380*160MM76*152MM100MMC3 is intelligent light bar panelD72*72MM68*68MM95MME/E548*96MM45*92MM100MME5 no front panel, DIN rail mounted.F96*48MM92*48MM100MM Note: D dimension instruments have no MIO slot, and its COMM and ALM share the same slot and can't be installed at the same time. Its ALM only support AL1 single loop alarm.(3)-(7)shows the module types installed on the following sockets: MIO (multiple input/output), OUTP (main output), ALM (alarm), AUX (auxiliary output), COMM (communication).

Note: Current module X3 and RS485 communication module S share the same power supply in the instrument, and are not electric isolated to each other. Therefore, if X3 current module is installed in OUTP slot and RS485 communication is need at the same time, then RS485 communication module should be S4 which itself has isolated power supply.
