【英文介绍】
The 1756-OF8H is an analog output module that is part of the Allen-Bradley Logix controller platform. The module has eight (8) voltage or current output channels and one (1) high-speed addressable Remote Sensor (HART) modem. Each channel can be configured for 0-20 mA and 4-20 mA output current signals, while configurable voltage output signals are +/-10 VDC. The resolution of all ranges of the module is 15-16 bits.
Allen-Bradley's 1756-OF8H ControlLogix Voltage/current analog Output module is an analog output module with eight voltage or current outputs, each with a HART modem. It has an optional voltage/current signal range of -10.4336-10.4336V and 0-21.2916mA. The 1756-OF8H has a total output rating of +/ -10V or 0-20mA and a signal resolution of 15-16 bits across all ranges. It also has backplane current consumption of 230 mA @ 5.1 VDC and 230 mA @ 24 VDC for a total backplane power of 6.54W. It has a heat dissipation of 16.78 BTU/ hour and a power consumption of 4.92W. The isolation voltage of the 1756-OF8H is 50V, and the basic insulation test between the output channel and the backplane lasts 60 seconds at 1500V AC.
Unlike other analog I/O modules, the 1756-OF8H provides open circuit detection, and the circuit detection time must be set to less than 0.1 mA. Its current build up time (without HART) is slightly less than 23ms, less than 37ms with HART, and voltage build up time with resistance load ranges from 8.5ms to 95%. Its calibration accuracy (HART free) is 0.1% (voltage) and 0.15% (current), and its standard calibration interval is about 12 months. The 1756-OF8H offset drift is 100 V/°C or 200nA/°C, and the module's overall module error is 0.15% (voltage) or 0.3% (current). It has T4 North America, ATEX and IEC temperature codes and is available in an open housing grade. The 1756-OF8H operates at a temperature range of 0 ° C to 60 ° C, with a relative humidity of 5-95% and no condensation.
