Besi Marine 93BE30 Temperature Controller & Sensor Interface
Model: 93BE30 (R205 20-053) | EDR201a-Druck Interface | 230V AC | 3 Relay Outputs
Product Overview
The genuine Besi Marine 93BE30 Temperature Controller (often indexed as R205 20-053), integrated with the specialized EDR201a-Druck Sensor Interface, is a heavy-duty, marine-grade instrumentation module engineered for critical shipboard automation. Operating on a standard 230V AC auxiliary power supply, this high-precision unit is equipped with 3 independent relay outputs (rated up to 250V / 2A) to drive alarms, interlocks, or active cooling systems. Highly versatile, it is designed to process inputs from Pt100/Ni100 RTD sensors as well as standard 4-20mA telemetry inputs. Built to withstand relentless hull vibration and harsh maritime environments, it serves as a crucial replacement or emergency spare for vessel engine rooms and industrial control systems.

Key Features & Operational Benefits
- Triple Relay Versatility: The 3 independent 250V/2A relays allow for complex multi-stage alarm logic, tripped interlocks, or cascading control loops from a single interface.
- Dual Signal Architecture: Natively interfaces with Pt100/Ni100 RTD elements or 4-20mA current loops, simplifying cross-platform integration into complex SCADA networks.
- Druck Signal Conditioning: Equipped with the advanced EDR201a-Druck conversion board to provide rapid telemetry response and clean noise suppression under industrial workloads.
- Marine-Grade Resilience: Rigid housing design and reinforced electronics shielding protect the internal processing units against continuous low-frequency hull vibration and saline moisture.
