System Protection Module
The System Protection Module protects the system from external transients by providing a “specific path” for currents to flow to ground in the case where the pipeline potential exceeds the normal utility ground.

Description
The SPM provides a convenient and safe path for excessive current to flow to ground bypassing the sensitive electronic circuitry in the RTU or other electronic device.
- Six Channel protection in one module
- Four Stages of protection. Inductance, Capacitance, High Energy Clamp, Fast Second Stage lower energy Clamp
- Physical layout of dual circuit board design keeps high energy and protected low energy components isolated. Energy dissipating resistors connect the stages of the two boards.
- Manufactured in a standard 3/4″ PVC conduit fitting. Makes installation easier. Installs in the conduit going to the equipment. Right, Left, and
- Straight through versions available.
- Available in Panel Mounted and Expansion Rack versions
- Pluggable pigtail allows easy wiring termination on the equipment side.
- Terminal screws for field termination.
- UL approval for use in intrinsic safe circuits.
- Multiple Versions avai1able including RS232, transducers and High Speed Devices.
