FAQ
Frequently Asked Questions (FAQ)
Q1: How many input channels does the DI803 module support?
A1: It supports 8 input channels at 230 V AC/DC with current sinking.
Q2: Are the channels electrically isolated?
A2: Yes, all 8 channels are individually isolated for enhanced safety.
Q3: What is the special role of Channel 8?
A3: Channel 8 can be configured for power supervision of Channels 1–7.
Q4: How does the digital filtering work?
A4: Noise pulses shorter than 2/4/8/16 ms can be filtered out; longer ones pass.
