APOLLO-2100 SEISMIC SWITCH

Rugged industrial seismic switch with tri-axial sensor, real-time PGA output, and 8-hour battery backup. Designed for critical shutdown protection in valves, pipelines, motors, and process control systems. NEMA-4/4X enclosure ensures reliability in harsh environments.

Price range: $8.595,00 through $8.995,00

OVERVIEW

Description

The Industrial Seismic Switch is a fully integrated monitoring system that combines a tri-axial digital seismic sensor (detecting both “P” and “S” waves) with a built-in 8-hour reserve battery for uninterrupted operation.
Each unit is shipped with a pre-drilled base plate for effortless installation. The standard model includes a NEMA-4 rated enclosure, while an optional stainless steel secondary enclosure provides NEMA-4X corrosion-resistant protection for harsh environments.

This smart seismic device offers user-configurable alarm setpoints, real-time Peak Ground Acceleration (PGA) outputs, and RS-232C serial communication for instant data retrieval.


Industrial Seismic Switch for Critical Applications

Ideal for mission-critical industrial environments where accidental shutdowns cannot be tolerated.
Applications include:

  • Valves, solenoids, and actuators
  • Process control systems
  • Pipelines and pumping stations
  • Hazardous material and chemical facilities
  • Electronic security doors
  • Motors and elevators

Key Features

  • Multi-Setpoint Sensor Control — User-selectable alarm thresholds from 0.025 g to 0.5 g, in 0.001 g increments per axis (X, Y, Z).
  • Real-Time Data Output — Continuous PGA data via RS-232C serial connection.
  • Automatic Self-Diagnostics — Power-on and periodic self-tests ensure operational integrity.
  • Battery Backup — Maintenance-free 8-hour internal battery guarantees operation during power loss.
  • High-Reliability Design — Solid-state triaxial accelerometer with ±0.001 g precision and no moving parts.
  • Rugged Industrial Output Relays — Form C (NO/NC) dry contacts rated up to 250 V / 6 A; user-selectable latching or timed alarm reset.
  • Easy Installation — Front-panel test/reset switch, LED status indicators, and ample wiring space.
  • Standards Compliance — Meets ASCE 25, ANSI Z21-70, ASME A17, and related seismic design standards.

Enclosure Options

  • Standard NEMA-4 Painted Steel: 15” W × 15” D × 10” H
  • Stainless Steel NEMA-4: 16” W × 16” D × 10” H
  • Stainless Steel NEMA-4X (with Secondary Enclosure): 24” W × 24” D × 12” H

Each enclosure features a fully gasketed door, status indicators (fault, AC power loss, seismic trip, and power on), and space for rigid or flexible conduit terminations.


Installation

The system is mounted via four ¼” bolts on the provided pre-drilled aluminum baseplate. Installation requires no precise leveling. The unit can also be wall-mounted in select configurations (consult factory). All wiring terminations are clearly labeled for quick field connection.


Available Options

  • 230 VAC / 50 Hz power supply
  • 24 VDC operation
  • Bypass switch(es)
  • Additional Form C trip relay contacts
  • Stainless steel NEMA-4X secondary enclosure
  • Custom logic integrations (flow, pressure, leak detection, or level monitoring feedback)
