• Ensure the rack power supply has sufficient capacity for the 700 mA draw.
• Use shielded, twisted-pair cables for each output to minimize noise interference.
• Connect cable shields to ground at the panel end only to prevent ground loops.
• Configure each channel's output range and scaling in Unity Pro software.
• Respect the 400-meter maximum cable distance to maintain signal integrity.

Technical FAQs

• What types of devices can this -10 to +10 mA output drive?

This bipolar range is ideal for controlling devices like proportional valves, servo controllers, or chart recorders that require a signal with a directional component (e.g., open/close, forward/reverse).

• How does the 12-bit resolution affect control precision?

12-bit resolution divides the 20 mA span (-10 to +10 mA) into 4096 steps. This provides a theoretical control increment of about 0.005 mA, allowing for very fine and smooth adjustments to your process.

• What is the benefit of the 500V channel isolation?

This high level of isolation prevents a fault or voltage spike on one output channel (or the field device) from damaging the other channels or the main controller, significantly improving system robustness.

• Can I use it to output a 4-20 mA signal instead?

While the hardware range is -10 to +10 mA, you can configure the software scaling in Unity Pro to use a subset like 4-20 mA. However, you must ensure your field device can interpret the chosen software range correctly.

• Why is there a 400-meter cable limit?

This limit ensures the voltage drop across the cable's resistance does not cause the current signal at the actuator to deviate unacceptably from the value set by the module, preserving control accuracy.
