Optical Sensors & Detector – Transducer for Photodiodes
Multiboard (TW-MF2CAB)
Multiboard TW-MF2CAB Modular Interface Board for Multi-Channel Signal Conditioning and Photodiode Sensor Integration
The TW-MF2CAB Multiboard is a versatile multi-channel interface and signal conditioning platform designed to connect, amplify, and synchronise multiple photodiode or sensor modules in one unified system.
Engineered for precision UV and optical measurement setups, it supports dual-channel operation for simultaneous input acquisition and configurable amplification through AMPCON transimpedance stages.
The board offers adjustable gain control, temperature-compensated circuitry, and low-noise signal routing, ensuring accuracy and stability for high-sensitivity SiC or GaP photodiodes.
Equipped with USB, RS-485, and analogue output options, the TW-MF2CAB allows seamless integration with VOLTCON controllers, UVMicroLog/UVMiniLog dataloggers, and SGLUX UVRRM reference systems.
Compact, modular, and industry-ready, the Multiboard simplifies multi-sensor connectivity for laboratories, production monitoring systems, and environmental UV networks requiring traceable, synchronised data acquisition.
Understanding Multiboard (TW-MF2CAB)
The TW-MF2CAB Multiboard acts as a centralised hub for connecting two or more UV or optical sensors, converting individual photocurrents into precise voltage outputs.
Each channel features an independent amplifier stage, filter circuit, and calibration interface, allowing fully isolated and noise-free operation.
Engineers can select or adjust the transimpedance gain for each channel via jumpers or digital control.
The system is ideal for applications that demand multi-point UV monitoring, such as curing chambers, disinfection tunnels, or sensor calibration benches.
With its compact layout and robust signal architecture, the Multiboard ensures accurate, stable, and coordinated sensor readouts.
