Analog (A) Module (RMC150)

Four 12-bit Analog Inputs

The Analog (A) module for the RMC150 provides four 12-bit resolution analog voltage or current inputs. This module does not include control outputs. The Analog (A) module is typically used for reference inputs, such as from a joystick, or for the secondary input of a position-pressure or position-force axis. The Analog (H) module front bezel is labeled Analog Inputs.

In addition to the Analog (A) 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 (G) Module
Two control outputs and two 16-bit analog voltage inputs for voltage-feedback position, velocity, pressure, or force control applications.

Features

Four isolated 12-bit inputs
8 times oversampling
±10 V, ±5 V, and 4-20 mA input ranges
+10 V exciter output
Broken wire detection

Part Number

The part number of the Analog (A) module is An, where n is the number of Analog (A) modules.

For example, RMC150E-M1-A1 is an RMC150E with one MDT and one Analog (A) module. RMC150E-S2-A2 is an RMC150E with two SSI and two Analog (A) modules.
