产品详细资料
R1和R2的建议值如下:R1=15K 1%,1W(26.4V时大功耗为47mW)R2=3K9 1%,1W(26.4V时大功耗为182mW)以上两种电路的建议值范围如下:假设:•回路电源电压=24V±10%•大现场电缆线路电阻:<100 全部的这意味着<50+50 两条电缆。•小隔离度为0.75M 场回路导体之间。•这些值将允许输入更准确地检测表示OPEN CCT-OFF-ON-SHORT CCT的不同电压电平,还将检测过电压和既非ON也非OFF的输入。这些值验证了在可能出现错误的接通和断开状态声明之前,是否会声明线路故障。F&G电路还允许两个设备处于报警状态,而不报告短路所有输入电路均适用于单工、双工和TMR配置。•F&G电路假设设备为无电压触点。
The suggested values for R1 and R2 are as follows: R1 = 15K 1%, 1W (maximum power dissipated is 47mW at 26.4V) R2 = 3K9 1%, 1W (maximum power dissipated is 182mW at 26.4V) Suggested range of values for both of the above circuits are as follows:Assumptions: • Loop supply voltage = 24V ± 10% • Maximum Field Cable Line Resistance: < 100 total; this means < 50 + 50 for the two cables. • Minimum Isolation is 0.75M between the field loop conductors. • These values will allow the input to detect more accurately different voltage levels that represent OPEN CCT - OFF - ON - SHORT CCT and will also detect Over Voltage and an input which is neither ON nor OFF. The values verify that a line fault will be declared before it becomes possible for a false declaration of On and Off states • The F&G circuit will also allow two devices to be in alarm without reporting short circuit. • All of the input circuits are suitable for simplex, dual and TMR configurations. • The F&G circuit assumes that the devices are volt-free contacts.
