Frequently Asked Questions and Selection Guide

• Question: Can I mix AC and DC loads on different channels of this module?
• Answer: You can mix different voltages only between the separate isolated groups of four output channels.
• Question: Does this module contain internal fuses to protect against overcurrent faults?
• Answer: This unit lacks internal short-circuit protection so you must install external fuses for safety.
• Question: How do I choose between relay outputs and transistor outputs for my application?
• Answer: Select relay variants for high current capacity and choose transistor versions for high-frequency switching tasks.
• Question: What causes premature failure of relay contacts during inductive load operation?
• Answer: Inductive voltage spikes degrade contacts quickly when you omit external RC snubbers or freewheeling diodes.
