Main Functions

1. 16‑channel digital signal acquisition：Support dry‑contact and wet 24 VDC input, collect status of auxiliary contacts of circuit‑breakers, valves, limit switches, proximity switches and relay feedback signals.
2. Group‑wise galvanic isolation：4 channels per isolation group, effectively eliminate ground‑loop interference when connecting field devices with different grounding reference points.
3. Hardware & software debounce filter：Hardware RC filter plus software configurable debounce time, eliminate contact bounce interference from mechanical contacts, avoid false signal flipping.
4. Full channel self‑diagnosis function：Detect field circuit open‑circuit, abnormal input voltage, internal circuit fault. Fault information with channel number is uploaded to DCS controller for alarm log.
5. Per‑channel LED status indicator
   • Green ON：Input channel logic‑high
   • Green OFF：Input channel logic‑low
   • Red flash：Channel fault status
6. Parameter configuration via Control Builder software：Input polarity inversion setting, debounce time adjustment, diagnosis function enable/disable, fault latch / auto‑reset mode.
7. Hot‑swap support：Module can be plugged and pulled out online without powering off the rack, convenient for maintenance and replacement.

Installation & Wiring Requirements

1. Insert module into Advant OCS standard rack slot, lock mechanical latch; back‑plane bus completes power supply and ModuleBus communication automatically.
2. Ensure cabinet ventilation, avoid conductive dust, corrosive gas and strong electromagnetic interference source nearby.
3. Separate digital‑input signal cables from high‑voltage AC power cables, keep wiring distance to reduce interference coupling.
4. For dry‑contact input application, external 24 VDC power supply shall meet power‑rating requirement; do not mix different potential power domains inside one isolation group.
5. Cabinet protective grounding must comply with industrial control grounding specification to guarantee isolation performance and anti‑interference capability.
6. Check input voltage shall not exceed 30 V DC maximum rating to prevent module damage.
