Prior to the LED test, the module will run through the loader, during which time it will
have a red CPU LED. After the LED test, the firmware will continue initialization, after
which time the LEDs resume their regular behaviors.
7.3.4. Analog Modules
7.3.4.1. Analog (H) Module (RMC150)
Two Control Outputs and Four 16-bit Analog Inputs
The Analog (H) module for the RMC150 interfaces to analog voltage or current transducers.
Providing four 16-bit resolution inputs, this module includes control outputs and is capable of
controlling pressure, force, and position applications. The Analog (H) module front bezel is
labeled ANLG.
The Analog (H) 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 more
susceptible to noise.
In addition to the Analog (H) module, the RMC150 supports the following analog modules:
 Analog (G) Module
Two control outputs and two 16-bit analog voltage inputs for voltage-feedback
position, velocity, pressure, or force control applications.
 Analog (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.
Features
• Four isolated 16-bit inputs
• 8 times oversampling
• ±10 V, ±5 V, and 4-20 mA input ranges
• +10 V exciter output
• Two isolated, ±10 V, 12-bit control outputs per module
• Current output up to ±200 mA with VC2124 converter option
Part Number
The part number of the Analog H module is Hn, where n is the number of Analog (H)
modules.
For example, RMC150E-H1 is an RMC150E with one Analog (H) module. RMC150E-H3-Q1
is an RMC150E with three Analog (H) modules and one Quadrature module.
Setting Up the H Module
