The Emerson 396509-05-3 (Series A) serves as a foundational component for the ControlWave™ Micro RTU/PLC system. This dual-purpose module provides both regulated power distribution and discrete signal interfacing. It delivers a steady 1000 mA @ 24 VDC to the backplane while simultaneously managing up to 16 configurable digital I/O channels. We provide this unit as 100% Brand New original stock, ensuring it meets all factory performance benchmarks for mission-critical infrastructure in oil, gas, and water sectors.
This module integrates power management and field signal processing into a single high-density slot:
| Feature | Specification |
| Input Voltage | +24 VDC Nominal |
| Backplane Output | 1000 mA @ 24 VDC |
| Field Power Rating | 3600 mA @ 24 VDC |
| I/O Capacity | 16 Configurable Digital Channels |
| Signal Type | Discrete ON/OFF (Dry Contact / 24 VDC) |
| Isolation | Optical/Electrical Isolation per Channel |
| Operating Temp | -40°C to +70°C (-40°F to +158°F) |
| Humidity | 5% to 95% RH (Non-condensing) |
| Hazardous Rating | Class I, Division 2 Approved |
Optimized Rack Space: By combining the power supply and 16 digital I/O channels into a single module, you free up backplane slots for additional specialized analog or communication cards.
Superior Thermal Resilience: The Series A design operates flawlessly in extreme environments ranging from -40°C to +70°C. It eliminates the need for external cabinet heaters or cooling fans in most remote terminal unit (RTU) deployments.
Robust Signal Integrity: Per-channel optical isolation shields the sensitive ControlWave processor from field-side electrical surges and ground loops, preventing hardware damage and data corruption.
High-Current Field Support: With a 3600 mA field power rating, the module provides ample current to drive multiple solenoids, actuators, and large relay banks directly from the rack interface.
Q: Can this module replace a standard power-only module in a ControlWave rack?
A: Yes, provided the rack configuration accounts for the 16 digital I/O points. The 396509-05-3 offers the same power delivery capabilities as standalone units but adds significant I/O density.
Q: How do I configure the channels as either Inputs or Outputs?
A: You define the channel direction through the ControlWave Designer software. The hardware supports flexible "Dry Contact" or 24 VDC typical discrete signals depending on your wiring and software logic.
Q: Does this unit include local termination?
A: The module supports local termination via the standard ControlWave Micro connector system. We recommend verifying your existing cable assembly compatibility if upgrading from an older Series card.
Q: Is this module compatible with Series B components?
A: This is a Series A module. While many ControlWave components maintain cross-series compatibility, you should verify the specific backplane version to ensure 100% timing and diagnostic synchronization.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
