PLC with integrated I/O MultiGard II

12-Ianalog inputsanalog outputs

Overview
MultiGard II is a pre-configured, programmable logic controller (PLC) engineered for blower safety and control. Designed for industrial blower systems, it monitors critical operating conditions in both constant-speed and variable-speed applications and supports limited multi-blower monitoring when only a subset of variables is required.

Key features

• Pre-configured, programmable logic controller (PLC) tailored for blower safety
• Compatible with constant speed and variable speed blower systems
• Scalable for monitoring multiple blowers when monitoring variables are limited

Hardware inputs / outputs

• Twelve 120 VAC digital inputs
• Twelve 120 VAC digital (relay) outputs
• Up to 24 analog inputs
• Up to four analog outputs

Monitor capabilities

• Surge detection and motor overload protection
• Bearing, inlet and discharge temperature monitoring
• Motor and bearing vibration protection
• Support for multiple blower applications with streamlined variable monitoring

Technical specifications & application scope

• Product type: Pre-configured PLC for blower safety and control
• Digital I/O: 12 inputs (120 VAC) / 12 relay outputs (120 VAC)
• Analog I/O: Up to 24 analog inputs, up to 4 analog outputs
