Working Principle

Advantage Highlights

1. Single field wiring terminal set for dual redundant IOMs, eliminates duplicate field cable runs
2. Sub-8ms redundant switchover time ensures zero loss of analog process measurement signals
3. Integrated HART multiplexing and surge protection built into redundant base unit
4. Certified for SIL 2 safety loop redundant analog input architectures
5. Single DIN rail mount simplifies redundant I/O rack layout engineering

Applicable Industries

Installation Requirements

1. Mandatory pairing with two identical redundant analog input IOMs (CC-PAIX01 / CC-PAIH01)
2. Install on 35 mm standard DIN rail inside Class 1 industrial control cabinet
3. All field analog cables utilize shielded twisted pair, single-point earth connection at CC-TAIX11 ground lug
4. Minimum 15 mm vertical clearance above chassis for passive heat dissipation
5. Cabinet protective earth bus hardwired to IOTA dedicated earth terminal screw

Usage Precautions

1. Both paired redundant IOM modules must run identical firmware revision versions
2. Do not exceed 30 VDC transient voltage applied to any field input terminal
3. Separate high-voltage power wiring from analog signal cables routed to CC-TAIX11
4. Avoid over-tightening terminal screws beyond specified torque rating to prevent housing damage
5. During IOM hot-swap maintenance, verify redundant secondary IOM online status before disconnecting primary unit
