RTU-Expander 3004 for Perseus, 30 digital inputs, 4 relay outputs, Modbus RTU, DIN rail - HW group 600929

For central distribution boards that collect dozens of alarm contacts, the RTU-Expander 3004 offers the highest input density of the series: 30 digital inputs and 4 relay outputs on 12 DIN rail modules, connected through a single RS-485 line.

Benefits

• Highest input density: 30 inputs for dry contacts such as smoke detectors, door contacts, motion sensors or power presence monitoring.
• Pulse counting: S0 pulse inputs compliant with EN 62053-31, Class B, record pulses from devices such as energy meters.
• Local switching: 4 relay outputs rated for 50 V and 1000 mA.
• Scales as needed: several RTU-Expanders can be daisy-chained from the RS-485 terminal block of one Perseus unit.
• Bus powered: 12 V nominal (GND and +U) is supplied through the same RS-485 terminal block.

Applications

• Central sub-distribution boards and control cabinets in data centers and plant rooms
• Collecting fault and common alarm contacts, for example from cooling systems or CDUs in liquid cooling
• Smoke, door and motion detectors from several rooms wired to one point
• Industrial installations monitored by Perseus

Compatibility

• HW group Perseus Industrial family devices, connected via Modbus RTU on the RS-485 terminal block
