• Input Type: Dry contact (dry), wet contact (24 V DC), PNP, NPN (configurable per channel group of 4)
• Input Current: 3 mA (typ.) per channel
• Isolation: 500 V DC (channel-to-channel, channel-to-bus)
• Scan Rate: 10 ms (standard), 1 ms (fast scan option)
• Diagnostics: Open wire detection, short circuit detection, stuck-at detection
• Communication: Ovation backbone bus (redundant A/B)

• Protection Class: IP20 (chassis-mounted)
• Certifications: CE, FCC, ATEX Zone 2 (optional), IEC 61508 SIL 2

Functional Features:

• Redundant A/B Bus: Automatic failover, zero data loss on bus switch
• Per-Channel Diagnostics: LED per channel (green = active, red = fault, off = inactive)
• Group Configuration: Channels 1–4, 5–8, 9–12, 13–16 independently configurable
• Debounce Time: 1 ms to 100 ms (software configurable)
• Fail-Safe Mode: Inputs default to defined state on communication loss

Performance Parameters:

• Operating Temperature: 0°C to +60°C
• Storage Temperature: -40°C to +85°C
• Relative Humidity: 5% to 95% (non-condensing)
• Vibration Resistance: 1 g (10–500 Hz, IEC 60068-2-6)
• Shock Resistance: 15 g (11 ms half-sine, IEC 60068-2-27)
• MTBF: >200,000 hours (at 40°C)

Material Composition:

• Housing: Zinc die-cast alloy, black epoxy coating
• PCB: FR-4, 4-layer, conformal coated (UL94 V-0)
• Terminals: Pluggable screw terminals, tin-plated, 1.5 mm² max
• Connectors: Ovation backplane connector, 96-pin DIN 41612

Structural Features:

• Dimensions: 220 x 125 x 25 mm (W x H x D)
• Mounting: DIN rail (35 mm) or chassis slot (Ovation rack)
• Weight: approximately 0.45 kg
• LEDs: 16 channel status LEDs + 2 bus status LEDs (A/B)

Working Principle:
Input signals are opto-isolated and sampled by the module’s FPGA at the configured scan rate. Data is transmitted over the redundant Ovation backbone bus (A and B) to the controller. On bus A failure, automatic switchover to bus B occurs within 10 ms with no data loss.

Applicable Industries:
Power generation (thermal, nuclear, hydro), oil & gas refining, chemical processing, pulp & paper, water treatment

Installation Requirements:

• Install in Ovation I/O rack (chassis slot or DIN rail)
• Use shielded cable for input signals, ground at one end
• Maximum cable length: 300 m (shielded twisted pair)
• Do not mix input types (dry/wet) on the same channel group without reconfiguration

Usage Notes:

• Configuration performed via Emerson DeltaV / Ovation Workstation software
• Do not apply voltage exceeding 30 V DC to any input
• Replace module only with Emerson 5X00225G01 or approved equivalent
• Periodic calibration per IEC 61508 schedule (typically every 24 months)
