Overview

The Moore Industries SPA/HLPRG/2PRG/U‑A0 Site Programmable Alarm belongs to the SPA2 series of programmable limit alarm trips. It is designed to provide on/off control, process condition warnings, rate‑of‑change alarms, and emergency shutdown functions in industrial automation systems. With its site‑programmable inputs and outputs, engineers can configure the device directly in the field without factory intervention.

This module is widely used in Safety Instrumented Systems (SIS) and general process monitoring applications, where reliable alarm signaling is critical.

Technical Data

Typical Applications

• Process monitoring: Detecting unwanted conditions in chemical, oil & gas, and power plants.

• Safety Instrumented Systems (SIS): Providing shutdown signals when thresholds are exceeded.

• Rate‑of‑change alarms: Identifying rapid changes in process variables.

• General automation: On/off control for pumps, motors, and actuators.

• Retrofit projects: Replacing legacy alarm trip modules with modern programmable units.

Key Features

• Universal input flexibility: Accepts current (4–20 mA, 0–50 mA) or voltage (0–10 VDC, 1–5 VDC).

• Dual relay outputs: Configurable for high/low alarms, shutdown, or control functions.

• Universal power supply: Operates on wide AC/DC ranges for global compatibility.

• DIN‑rail mounting: Compact and easy to install in control panels.

• Field programmability: No factory return required for reconfiguration.
