Current/Voltage Input Module (Simpli?ed Type) 电压/电流输入模块(简化型)
This module receives 4-20 mA from 2-wire transmitters and 1-5 V standardized signals.
Items Speci?cations
Model AAM10
Input signal 1 to 5 V DC 4 to 20 mA DC (*1) (*2)
(It is possible to supply power to a transmitter)
Input resistance 1 M? at power-up (100 k? at power-down) 250 ?
Allowable input voltage/current -10 to 30 V DC 40 mA DC or less
Transmitter power supply - 25.0 to 25.5 V DC
(Output current limit: 60 mA DC or less )
Auxiliary voltage output None
Square root extraction None
Accuracy Voltage input: _4 mV; Current input: _16 mA
Effect of ambient temperature For 10 _C change: Voltage input: _8 mV
change Current input: _32 _A
Data update period 50 ms
Current consumption 250 mA or less (5.0 V DC)
Signal isolation Input signals are isolated between systems. Withstanding voltage: 1500 V AC/min
How installed Installed in the I/O Module Nest.
How connected Connected to the terminals of the I/O Module Nest with M4 screws.
How input signals are speci?ed Specify input signals and range by software setting.
*1: This module can be combined with MTL barrier 728. At this time, wiring resistance must be 10 ? or less and the lowest operating voltage of the 2-wire transmitter must be 12 V DC or less.
*2: When the power of AAM10 is OFF or an abnormal condition occurs, the current input loop is open. Do not share current signals with other receivers. To share signal, attach Shunt Resistance (250 ?) to current-output module and share voltage output.
