Phoenix IB IL 24 DO Series: Distributed Digital Output Modules - Selection Guide
Product Overview
The Phoenix IB IL 24 DO Series consists of distributed digital output modules designed for IB bus industrial automation systems. Featuring 24V DC power supply, 35mm DIN rail mounting, and flexible packaging (PAC plug-and-play, standard), these modules cover diverse channel configurations (2/4/8/16/32 channels) and functional variants—including high-density (HD), NPN output, dual-stable (2MBD), enhanced function (EF), and special-purpose (ME) models. With output current ratings up to 2A per channel and compliance with industrial standards, they enable reliable load control for actuators, valves, relays, and other industrial devices in distributed automation setups, control cabinets, and manufacturing lines.

Application Scenarios & Recommended Models
1. High-Density Cabinet Installations
- Requirement: 32-channel DO in space-constrained cabinets
- Recommended Model: 2862822 (IB IL 24 DO 32/HD-PAC)
- Key Reason: HD high-density design minimizes cabinet space; PAC plug-and-play for quick deployment
2. NPN-Type Load Control
- Requirement: NPN-compatible digital output (e.g., NPN sensors/actuators)
- Recommended Models: 2878340 (32-channel HD), 2861496 (2-channel PAC)
- Key Reason: NPN output type matches NPN load polarity; high-density/compact options available
3. High-Current Load Control (2A)
- Requirement: 2A per channel for small motors, valves, or heavy relays
- Recommended Models: 2861263 (2-channel PAC), 2861603 (8-channel PAC)
- Key Reason: 2A current rating handles heavy loads; PAC packaging simplifies installation
4. Latching Control (Dual-Stable)
- Requirement: 8/16/32-channel latching function (no power retention)
- Recommended Models: 2861687 (8-channel), 2862013 (16-channel), 2692898 (32-channel)
- Key Reason: 2MBD dual-stable design maintains output state without continuous power
5. Extreme Temperature Environments
- Requirement: 8-channel DO for -40℃~85℃ operating conditions
- Recommended Model: 2701213 (IB IL 24 DO8/HD-XC-PAC)
- Key Reason: XC extended temperature rating; HD high-density for space efficiency
6. Basic Fixed Installations
- Requirement: Cost-effective DO for non-mobile setups
- Recommended Models: 2726256 (4-channel), 2726269 (8-channel), 2740106 (2-channel)
- Key Reason: Standard mounting (no PAC) for permanent installations; cost-effective basic functionality
Core Advantages
- IB Bus Specialization: Seamless compatibility with IB bus distributed automation systems
- Flexible Channel Configurations: 2~32 channels cover small-to-large scale load control needs
- Dual Packaging Options: PAC plug-and-play for fast deployment; standard mounting for fixed setups
- Functional Diversification: NPN output, 2A high-current, dual-stable latching, and extended temperature (XC) variants
- High-Density Design: HD models maximize control cabinet utilization (up to 32 channels per module)
- Industrial-Grade Reliability: -25℃~70℃ standard operating temperature, 2kV insulation, and IP20 protection
- Global Compliance: CE/UL/CSA certifications enable international deployment in industrial applications
Installation & Usage Notes
- Bus Compatibility: Ensure modules match the IB bus system version (check firmware for integration)
- Voltage Matching: Power modules with 24V DC (19.2~28.8V) to avoid malfunctions or damage
- Polarity Attention: NPN-suffixed models require correct NPN load wiring (verify polarity before power-on)
- Current Limitation: Do not exceed 2A per channel for 2A variants; use relays for loads >2A
- Mounting Spacing: Reserve ≥5mm between modules for heat dissipation, especially for 16/32-channel HD models
- PAC Connector Handling: Avoid damaging plug-in connectors during installation; ensure full insertion for secure connections
- Dual-Stable (2MBD) Wiring: Follow latching control guidelines (requires set/reset signals for state changes)
- Environmental Protection: Install in dry, dust-free control cabinets (IP20 protection); avoid direct moisture exposure
