Physical Design and Interface Details
The AMM11 adopts a compact footprint that fits standard Yokogawa I/O racks. Its dimensions measure 130 mm in length, 100 mm in width, and 25 mm in depth. Moreover, the module weighs roughly 250 grams, which simplifies rack installation and field replacement. Twenty screw terminals secure field wiring without specialized tooling.
Performance and Signal Processing Capabilities
This module multiplexes sixteen voltage inputs into a single acquisition path. The 16:1 multiplexing ratio reduces hardware overhead while maintaining signal integrity. The 16-bit A/D conversion delivers high-resolution data for demanding measurement loops. Additionally, channel-to-channel isolation prevents interference between adjacent inputs. Consequently, the unit suits dense monitoring applications requiring tight tolerances.
Power and Environmental Considerations
The AMM11 operates on a 24 V DC nominal power supply. Power consumption remains approximately 3.5 W during normal operation. The operating temperature range spans 0°C to 55°C for industrial environments. Storage temperature extends from -20°C to 70°C. Furthermore, humidity tolerance reaches 95% RH without condensation.
