104 POINT I/O Module Data
Analog Input Modules
The 1734-IE2C Analog Input Module is a two-channel module that converts
an analog input current to a digital value. The module resolution is 16 bits
across 0 to 21 mA. The module has two modes.
• 0…20 mA
• 4…20 mA (default mode)
• Scaling to any 16-bit signed integer (–32,768…+32,767) -
Default for 1734-IE2C scalers are +3277 @ 4 mA for low
and +16,383 @ 20 mA for high
• Operates in Unipolar mode
The 1734-IE2V Analog Input Module is a two-channel module that converts
an analog input voltage to a digital value. The module resolution is 16 bits
across -10…+10V. The module has two modes.
• 0…10V dc (default mode)
• +/- 10V dc
• Scaling to any 16-bit signed integer (–32,768…+32,767) -
Default for 1734-IE2V scalers are 0 @ 0V for low
and +10,000 @ 100V for high
• Operates in Unipolar or Bipolar modes
