Allen-Bradley 100S-F Safety Contactor
The Allen-Bradley 100S-F, also cataloged as the 100S-F Safety Contactor, operates as a dedicated hardware component for hazardous power isolation and safety circuit interlocks within industrial safety systems. It directly de-energizes high-voltage power lines and drives safety-critical motor loads upon receiving trip commands from emergency stop loops, machine guarding interlocks, or two-hand control units.

Firmware Flash Compatibility and Deterministic I/O Integration
Engineered for integration with Allen-Bradley safety PLC racks and Guard I/O architectures, the safety contactor operates reliably in high-density control enclosures without disturbing backplane bus communication velocity. Mechanically linked auxiliary contacts provide positive-guided feedback status directly to safe EtherNet/IP deterministic networks. This enables controller-level diagnostic verification during firmware flash compatibility updates and safety-state validation checks without false feedback trips.
Frequently Asked Questions
Q: How do the auxiliary contacts on the 100S-F support safety circuit monitoring?
A: The contactor uses mechanically linked (positively guided) auxiliary contacts to ensure the normally closed (NC) monitoring contacts never close simultaneously with the normally open (NO) power contacts, allowing safety relays to reliably verify contact state.
Q: Can the 100S-F be installed in standard industrial control enclosures?
A: Yes, the unit supports standard 35 mm DIN rail or direct panel mounting and features an IP20 or higher enclosure rating for installation within standard control panels.
Field Installation Guidelines
- Disconnect all primary line power and auxiliary control power before installing or servicing the safety contactor.
- Securely mount the unit onto a standard 35 mm DIN rail or screw-mount it onto a panel backplate using proper torque limits.
- Terminate power cables and auxiliary feedback circuits using properly sized copper conductors and tighten terminal screws firmly.
- Wire the mechanically linked auxiliary NC contacts directly into the feedback loop of the safety relay or Guard I/O module to ensure active fault monitoring.
- Verify mechanical movement and electrical isolation prior to applying main power to connected motor loads.
