The Allen-Bradley 100-FSV136, also cataloged as the 100-FSV136 Surge Suppressor Module, operates as a dedicated hardware component for transient voltage spike attenuation within Bulletin 100 contactor and control circuits. The varistor-based circuit clamps high-voltage transients generated by inductive load switching, maintaining voltage levels within specified limits across 56-136 VAC or 78-180 VDC control lines.

Backplane Bus Communication & Hardware Execution
Integrated directly onto the contactor coil terminals, the 100-FSV136 module protects backplane bus communication velocity and firmware flash compatibility of connected PLC output cards. By absorbing inductive voltage spikes right at the coil source, the suppressor prevents electromagnetic interference (EMI) noise coupling into EtherNet/IP deterministic networks or adjacent I/O modules, preventing false logic triggers and backplane comms dropouts.
Frequently Asked Questions
Q: Does the installation of the 100-FSV136 varistor module increase the contactor drop-out delay time?
A: Varistor-based suppressors add minimal off-delay to the contactor drop-out time (typically 2-5 ms), maintaining predictable coil release characteristics compared to diode-based suppression circuits.
Q: Is the 100-FSV136 module polarity-sensitive when operating on DC control circuits?
A: No, the metal oxide varistor (MOV) construction provides bidirectional clamping capability, allowing connection across the coil terminals regardless of DC polarity orientation.
Field Installation Guidelines
Ensure main incoming control power is de-energized and locked out prior to physically attaching the module to the contactor coil terminals.
Snap the 100-FSV136 directly onto the front coil terminal slots of the compatible Bulletin 100 contactor or control relay until the retention latch engages.
Verify that terminal connection pins align properly with the coil screws and tighten the terminal screws to the manufacturer-specified torque limits.
Keep control loop wiring short and direct to avoid forming inductive loops that could pick up ambient electromagnetic interference.
Inspect the module body periodically for discoloration or structural damage resulting from severe power line voltage surges.
