Key Parameters and Features
Core Features & Advantages
-
Flexible, Field-Configurable Output Range: The module's standout feature is its ability to be configured on the fly for either the standard 4–20 mA or the 0–20 mA range using a simple hardware jumper . This flexibility allows it to adapt to a wide variety of field devices and application needs without requiring additional components or reprogramming.
-
High Precision with Configurable Fail-Safe Behavior: The module delivers reliable 13-bit resolution and industry-standard accuracy, ensuring precise control over actuators . It also allows users to define the output state in case of a system fault, choosing to either hold the last value or go to the low end of the range, which is critical for maintaining process safety during communication loss .
-
Hot-Swap Capability for Minimal Downtime: The module supports hot insertion, allowing it to be replaced without powering down the system. This capability significantly reduces downtime for maintenance . However, it is important to note that improper hot insertion can potentially disrupt other modules on the same backplane .
Typical Applications
The IC200ALG326 is widely used in process and discrete manufacturing applications requiring precise analog control of output devices, such as :
-
Process Control: Driving current-to-pressure (I/P) transducers, proportional valves, and positioners in chemical and refining plants.
-
Industrial Machinery: Controlling variable frequency drives (VFDs) and servo drives for speed and torque control in material handling and packaging.
-
Building Automation: Regulating dampers, valves, and pumps in HVAC systems.

FAQ
Q1: Can the IC200ALG326's output range be changed?
A: Yes. The module's default current output range is 4–20 mA, but it can be configured for 0–20 mA by installing a jumper wire on the field terminals . The range jumper is located at terminal B1 (JMP 1) .
Q2: How many output channels does it provide?
A: The module provides eight single-ended current output channels, all arranged in a single group .
Q3: What is the module's resolution and update rate?
A: The IC200ALG326 features 13-bit resolution (approximately 2.5 µA per count) and a maximum module update rate of 15 ms .
Q4: Can the module retain output states during a power or communication loss?
A: Yes. A configuration jumper (located at terminal B3 for hold function) allows you to set the outputs to either hold their last state or default to the low end of the range (0 or 4 mA) if backplane power, communication, or the PLC is interrupted . This requires the external field power supply to remain uninterrupted .
Q5: What is the module's accuracy?
A: At 25°C, the accuracy is ±0.3% typical and ±0.5% maximum of full scale. Over the full operating temperature range (0 to 60°C), the maximum accuracy is ±1% .
Q6: What load types does the module support?
A: The module supports a maximum resistive load of 800 Ω (dependent on field voltage), a maximum capacitive load of 1.0 µF, and a maximum inductive load of 0.5 H .
Q7: Is the module hot-swappable?
A: Yes, the IC200ALG326 supports hot-swapping for easy maintenance . However, it is recommended to turn off power first or perform the procedure correctly, as improper hot insertion could disrupt backplane power .
Q8: What do the LED indicators show?
A: The module has two green LEDs :
Q9: What cable type is recommended for wiring?
A: Shielded twisted pair cable is recommended for all analog channel connections to reduce signal noise .
