7.3.4.3. Analog (G) Module (RMC150)
Two Control Outputs and Two 16-bit Voltage Inputs
Note: Delta recommends using the Ho module instead of the G module. The similarly-priced H
module has four analog inputs instead of two, and supports 4-20 mA feedback.
The Analog (G) module for the RMC150 interfaces to analog voltage transducers (current is
not supported). Providing two 16-bit resolution inputs, this module includes control outputs
and is capable of controlling pressure, force, and position applications. The Analog (G) module
front bezel is labeled ANLG2.
The Analog (G) module can be used for position control. However, higher precision of position
can typically be obtained with MDT or SSI feedback. Analog systems are often very susceptible
to noise.
In addition to the Analog (G) module, the RMC150 supports the following analog modules:
 Analog (H) Module
Two control outputs and four 16-bit inputs for controlling position, velocity, pressure,
or force.
 Analog Inputs (A) Module
A four-input 12-bit analog module with no control outputs. Used for reference inputs,
or the secondary inputs of position-pressure or position-force axes.
