Omron C200H-DA003
Original price was: $350.00.$236.00Current price is: $236.00.
The Omron C200H-DA003 is a high-performance Analog Output Module designed for the legendary Sysmac C200H series PLCs.1 This module allows the PLC to control external devices that require a continuously variable signal, such as Variable Frequency Drives (VFDs), proportional valves, or chart recorders.
Even though the C200H series is legacy hardware, the DA003 remains a critical component in many existing industrial installations due to its reliability and high resolution.
1. Signal Specifications
The “DA” in the model name stands for Digital-to-Analog. This specific module converts digital values from the PLC into analog current or voltage signals.
-
Number of Channels: 8 Analog Outputs.2
-
Output Signal Types:
-
Voltage: 3$0$ to 4$10V$, 5$-10$ to 6$+10V$, or 7$1$ to 8$5V$.9
-
Current: $4$ to $20mA$ (ideal for long-distance signals to minimize noise).
-
-
Resolution: 1/4096 (12-bit). This provides high precision for fine-tuned control of machine speeds or valve positions.
2. Connectivity and Wiring
The module features a removable terminal block, allowing you to replace the hardware without disconnecting all the individual wires.
-
Terminal Type: 20-point screw terminal block.
-
External Power Supply: Requires an external 24V DC power source to drive the analog output loops.
-
Isolation: The module features optocoupler isolation between the PLC bus and the external output terminals to protect the CPU from electrical surges.
3. Technical Specifications
| Feature | Details |
| Model | C200H-DA003 |
| I/O Points | Occupies 10 “Special I/O” words |
| Conversion Time | Max 4 ms per 8 channels |
| Accuracy | $\pm 0.3\%$ of full scale at $25^\circ C$ |
| Internal Current Consumption | $100mA$ (at 5V DC from the backplane) |
| External Power Consumption | $200mA$ (at 24V DC) |
4. Configuration and Setup
Unlike modern “Plug-and-Play” modules, the C200H-DA003 requires manual hardware configuration:
-
Unit Number Switch: A rotary switch on the front panel sets the “Unit Number” (0–F). This determines the memory addresses (IR/CIO words) assigned to the module in the PLC.
-
Output Range Settings: Small DIP switches or jumper pins (depending on the revision) located on the side or back of the module are used to select between Voltage and Current for each channel.
5. Common Troubleshooting
-
“ERC” LED Lit: This usually indicates a hardware error or a configuration mismatch in the PLC settings.
-
No Output Signal: Check the external 24V DC supply. Analog modules cannot generate a signal using only the PLC backplane power.
-
Signal Drift: If the output is inconsistent, ensure that the shielded cable’s ground is connected at only one end to prevent ground loops.
