FAQ

Q1: Can the module handle both digital and analog signals simultaneously?
A1: Yes, it integrates discrete inputs/outputs and analog inputs/outputs within one unit.

Q2: What analog signal types are supported?
A2: Standard industrial signals including 0–10 V, ±10 V, and 4–20 mA.

Q3: Is system downtime required for replacement?
A3: No, the module supports hot-swapping for continuous operation systems.

Q4: How is communication handled?
A4: Through Modbus and RS-485 directly, with Ethernet available via the system backbone.

Q5: Does it support redundancy?
A5: Yes, redundant power input is supported, and system-level redundancy depends on controller configuration.
