| Frequently Asked Questions |
|
Q1: Is the I/O electrically isolated?
No—none of the digital I/O or counters are galvanically isolated; shared L– reference is used.
Q2: What if there's a fault or overload?
The controller auto-detects short circuits, voltage faults, or overloads and deactivates affected I/O to put them in a safe state.
Overtemperature (>70 °C), overvoltage, or undervoltage are similarly handled.
Q3: Can it handle Modbus communication?
Yes—it supports Modbus over RS‑485 and works as an OPC client for data exchange.
Q4: What’s the power requirement?
Requires a 24 V DC, up to 8 A supply (1 A for controller, 7 A usable by I/O). Use a slow-blow fuse.
