Frequently Asked Questions
- What is the minimum load current required for the relay contacts?
The system requires a minimum load current of 5mA to maintain reliable contact closure. - Can I use this module for high-frequency pulse switching?
No, the mechanical nature of these relays limits resistive switching to a maximum of 2Hz. - Does this module include built-in diagnostic alarms for wire breaks?
This specific model does not support diagnostic alarms or wire-break detection features. - Why should I choose this relay module over a transistor output module?
Relays provide physical potential separation and handle higher AC voltages compared to standard transistors. - How do I manage the group-based output structure?
The 8 outputs operate in groups of 2, allowing for flexible circuit partitioning per application.
