Description
RPM420 is a multipurpose I/O module for use in Alarm monitoring andIntegrated Control Systems. RMP420 is designed for 32 field input channelsin single topologies. Its interface towards the host control computer (RCU) isprovided 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 withhost computer(s). • Communication ports galvanically insulated from other module circuitry. • Loop monitoring (per channel).
BENEFITS • Over-voltage protection • Extensive module diagnostics • I/O channels onlineconfigurable • Soft and hard fail-safe • Dual watchdog • Certified for use inhazardous area zone 2 • RIO module and I/O loop,powered from the samesource • Automatic recovery protection e.g. automaticstart of faulty channels • Easy installation andreplacement • Simple and safe FW upgrade • Status LED
