RMP420  Remote Multipurpose Input/Output

RPM420 is a multipurpose I/O module for use in Alarm monitoring and Integrated Control Systems. RMP420 is designed for 32 field input channels in single topologies. Its interface towards the host control computer (RCU) is provided by redundant I/O bus.
The module is approved for Ex Zone 2 applications.
Functions
• 32 software configurable multipurpose solid-state channels.
• Analog and Digital Input and Output (AI, AO, DI and DO).
• 2 or 3 wire Resistance Temperature Detector (RTD).
• 2 channels can be configured as pulse/frequency/encoder input.
• Short-circuit protected I/O loop power output.
• Dual Remote I/O process BUS interface for redundant communication with host computer(s).
• Communication ports galvanically insulated from other module circuitry.
• Loop monitoring (per channel)
