Overview
Processor Status Contact
The processor status contact provides an external indication of CPU abnormality. The contact opens when the CPU enters an abnormal state, allowing an external monitoring or alarm circuit to detect the condition. Its rated load must not exceed 30 VDC and 0.3 A.
Power Supply Configuration
The available power supply options are specified by suffix code. The listed configurations cover two AC voltage ranges and one DC supply option:
- 100-120 VAC at 50/60 Hz
- 220-240 VAC at 50/60 Hz
- 24 VDC
The selected supply voltage must match the converter’s ordered configuration. Confirm the complete model and suffix before connecting the power supply.
