C200H-DA003

What type of module is this?

The C200H-DA003 is an eight-channel analog voltage output module for Omron C200H-series PLC systems. It converts digital values from the PLC into voltage signals used by compatible field devices.

How many analog output channels does the module provide?

It provides eight analog voltage output channels, allowing one module to control up to eight compatible devices or process signals.

Which output signal ranges are supported?

The module supports 1 to 5 V, 0 to 10 V, and -10 to +10 V output ranges. The required range is configured for each output through the PLC's allocated data memory.

Is this an analog input or analog output module?

It is an analog output module. The DA designation identifies it as a digital-to-analog unit that sends voltage signals from the PLC to external equipment.

Which PLC series is this module designed for?

It is designed for use with Omron C200H-family PLC configurations, including supported C200H, C200HS, C200HE, C200HG, and C200HX systems. CPU compatibility and rack capacity should be checked before installation.

What are typical applications for this module?

Typical uses include providing analog reference signals to variable-frequency drives, valve positioners, process controllers, actuators, indicators, and other equipment that accepts a compatible voltage input.

How is the module mounted?

The module mounts into a compatible C200H backplane slot. Its upper hook is engaged first, after which the module is rotated into position and secured using the lower locking lever.

How does the PLC exchange data with the module?

The PLC exchanges operating data with the module through allocated IR and DM areas. The selected unit number determines which words are assigned to the C200H-DA003.

How is the unit number selected?

A rotary unit-number switch on the front of the module assigns its IR and DM word ranges. Each Special I/O Unit in the PLC must have a unique setting to prevent an I/O UNIT OVER error.

What do the front indicators show?

A steadily illuminated green RUN indicator shows normal operation, while a flashing RUN indicator identifies adjustment mode. An illuminated red ERROR indicator means the module has detected an error.

What cable type is recommended for the analog outputs?

Shielded twisted-pair cable is recommended for external output connections. Analog cables should be routed separately from AC wiring, high-voltage cables, main circuits, and other potential sources of electrical interference.

What terminal hardware should be used?

The terminal block accepts crimp-style fork or ring terminals for M3 screws, with a maximum terminal width of 6.0 mm. The specified tightening torque is 0.5 N·m.

Can individual output channels use different voltage ranges?

Yes. The required output use and signal range are defined through the module's allocated data memory, allowing channels to be configured according to the connected equipment.

Does the module provide output hold functionality?

Yes. Its output hold function determines the output behavior during operating-state changes or specified PLC conditions. The required behavior should be configured to suit the machine's control sequence.

Can its offset and gain be adjusted?

Yes. The module includes a dedicated adjustment mode for offset and gain calibration. The rear operation-mode switch must be set correctly, and normal mode should be restored before regular operation.

What should be checked when replacing an existing unit?

Confirm the full model marking, voltage-output requirement, number of channels, selected signal ranges, unit-number setting, terminal assignments, rack compatibility, and IR/DM configuration. The replacement should match the existing application rather than being selected by appearance alone.
