4 Voltage or Current Outputs, with Fault Inputs and Enable Outputs
The CA4 module for the RMC200 provides 4 analog outputs intended for controlling an actuator. With individually configurable ±10 VDC, ±20 mA, or 4-20 mA, the CA4 can connect directly to a wide range of actuators. Each analog output has an associated Fault Input and Enable Output.
Features
4 analog outputs: ±10 VDC, ±20 mA, or 4-20 mA, individually configurable
Supports custom ranges within the ±10 VDC and ±20 mA ranges, such as 0-10 V, 0-5 V, 1-5 V, etc.
18 bit resolution
(4) 24 VDC Enable outputs
(4) 24 VDC Fault Inputs
Enable inputs and Fault outputs may be used as general-purpose discrete I/O
Unpluggable terminal blocks
Part Number
The part number of the CA4 module is R200-CA4.
Setting Up the CA4 Module
Wiring
See CA4 Wiring.
Axis Definitions
In order to use a CA4 analog output, it must be assigned to an RMC internal software axis, via the Axis Definitions Dialog.
Output Parameters
After a CA4 analog output has been assigned to an axis, the following axis parameters must be configured:

Description |
|
Off |
No power to the RMC200 or the module was not inserted when the RMC200 powered up. |
|
Blue |
The module was recognized at power-up. |
Control Output LEDs: Out0 .. Out3
|
State |
Description |
|
Off |
Not assigned The output is not assigned to an axis. |
|
Green |
Operating normally The axis is operating normally with no latched errors. |
|
Red |
Error The axis has at least one error bit set that has halted the axis. |
|
Amber |
Simulate mode The axis is in simulate mode. |
Enable Output LEDs: En0 .. En3
|
State |
Description |
|
Off |
Enable Output inactive The Enable Output is currently inactive. If configured as an axis Enable Output, the output may be Active Closed or Active Open, but when a general purpose output, it will always be Active Closed. |
|
Green |
On - as Enable Output The Enable Output is configured as an axis Enable Output and is currently active (may be configured as Active Closed or Open). |
|
Yellow |
On - as general-purpose output The Enable Output is configured as a general-purpose output, and the output is currently closed (active). |
Fault Input LEDs: Flt0 .. Flt3
|
State |
Description |
|
Off |
Fault Input inactive The Fault Input is inactive (logically off). If configured as an axis Fault Input, the input may be active high or active low, but when a general purpose input, it will always be active high. |
|
