Altitude Operating Conditions
The characteristics in the tables below apply to the modules BMX AMO 0210 and BMX AMO 0210H for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.

Voltage Output
The BMX AMO 0210 and BMX AMO 0210H voltage outputs have the following characteristics.
Nominal variation range
+/-10 V
Maximum variation range
+/- 11.25 V
Analog resolution
0.37 mV
Load impedance
1 KΩ minimum
Detection type
Short circuits
Current Output
The BMX AMO 0210 and BMX AMO 0210H current outputs have the following characteristics.
Nominal variation range
0..20 mA, 4..20 mA
Available maximum current
24 mA
Analog resolution
0.74 µA
Load impedance
600 Ω maximum
Detection type
Open circuit(1)(2) 
(1)
The open circuit detection is physically detected by the module if the target current value is different of 0 mA. 
(2)
Open circuit detection is enabled with the Wiring CTRL parameter.
Response time of Outputs
The maximum delay between transmission of the output value on the PLC bus and its effective positioning on the terminal block is less than 2 ms:
NOTE: If nothing is connected on the BMX AMO 0210 analog module and the channels are configured in the range 4..20 mA, there is a detected I/O error as if a wire is broken.
For the 0..20 mA range, there is a detected I/O error as if a wire is broken only when the current is greater than 0 mA.
CAUTION
RISK OF INCORRECT DATA
If a signal wire is broken or disconnected, the last measured value is kept.
  • Ensure that this does not cause a hazardous situation.
  • Do not rely on the value reported. Check the input value at the sensor.
Failure to follow these instructions can result in injury or equipment damage.
