Product Introduction & Supply Chain Strategy
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. The IFM AC1028 serves as an IP67 field-mounted AS-Interface I/O module, interfacing digital limit switches, inductive proximity sensors, and solenoid valves directly to an AS-Interface master scanner.
Securing a genuine New Surplus AC1028 for your local buffer stock eliminates severe total cost of ownership (TCO) risks caused by field network outages. Second-hand or repaired field blocks often suffer from degraded insulation displacement contacts (IDC) and compromised O-ring seals from past thermal cycles. Holding factory-sealed inventory on-site guarantees full 10 to 15 year operational longevity, preventing $50,000 per hour unplanned conveyor and packaging line outages.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Enforce strict Lock-Out/Tag-Out (LOTO) protocols on the 24 V DC auxiliary power supply and AS-i power conditioner.
- Verify the AS-i yellow flat cable and black auxiliary power cable are free from outer jacket tears.
- Note the target slave address (1 to 31 or 1A to 31B) assigned to the replacing field module.
Stage 2: Removal
- Unplug all M12 sensor and actuator connector cables from the front face of the module.
- Loosen the central mounting screw securing the upper AC1028 module body to the lower base plate.
- Lift the upper module straight off the mounting base to disengage the insulation displacement blades from the flat cable.
Stage 3: Installation (Clone & Seat)
- Address the new AC1028 module using an IFM hand-held addressing unit (AC1154/AC1144) via the addressing socket before mounting.
- Align the module housing over the lower mounting base, ensuring the AS-i flat cable lies flat in its guide channel.
- Tighten the central mounting screw to drive the gold-plated insulation displacement contacts through the flat cable, establishing a watertight IP67 seal.
Stage 4: Power-On & Testing
- Reconnect all M12 field cables to their corresponding digital input/output sockets.
- Energize the AS-Interface bus and check the front LED indicators: confirm solid green PWR (Power) and solid green FAULT (no bus errors).
- Toggle field inputs to confirm active LED channel feedback and verify successful cyclic communications with the AS-i Master scanner.
Firmware/Software Versions & Upgrade Notes
- AS-i Slave Profile: Uses Slave Profile S-7.A.E (4 inputs / 4 outputs, extended addressing mode).
- Master Compatibility: Fully compatible with all AS-Interface v2.1 and v3.0 Master Gateways (e.g., IFM AC1401/AC1402, Siemens CP343-2, or Allen-Bradley 1769-SM2).
- Addressing Notes: If substituting an older AS-i v2.0 module, ensure the AS-i Master scanner supports Extended Addressing (A/B slave structure) to prevent node configuration mismatches.
Frequently Asked Questions (FAQ)
Q: Why is your New Surplus pricing lower than OEM direct, but higher than refurbished options?
A: Our pricing reflects the market cost of securing genuine, unused global inventory. Refurbished parts are cheap because they carry high failure risks from corroded insulation displacement blades and cracked housings. Our New Surplus inventory delivers original OEM quality at a fraction of factory list price.
Q: Is this IFM AC1028 field module truly unused?
A: Yes. Every unit is brand-new, stored in protective packaging, and shows zero wear or puncture marks on internal contact blades. Packaging is opened solely for visual inspection and quality verification.
Q: Can I hot-swap the module while the AS-Interface bus is powered?
A: Yes. AS-Interface modules support live removal and replacement on the yellow flat cable. However, ensure connected field actuators are placed in a safe state before disconnecting the module.
Q: Do I need an addressing cable to configure this unit?
A: Yes. You can program the slave address through the M12 addressing socket using an AS-i handheld addressing device, or automatically via an AS-i Master that supports automatic slave replacement (if only one node is missing).
Q: What warranty coverage comes with this module?
A: We provide a full 1-year replacement warranty on all New Surplus modules, covering complete functional operation under standard industrial operating conditions.
