4-20 mA Input Module
The 4–20 mA Input Module is a GOcontroll Moduline-compatible expansion card designed to interface with passive industrial-grade sensors using the 4–20 mA current loop standard. It adds ten current loop input channels to your modular controller, allowing for accurate and reliable acquisition of analog, current loop based process signals.
Each input is equipped with diagnostic capabilities such as wire break detection. The module also features onboard power supplies (Active current loop) and configurable filtering, ensuring stable operation even in electrically noisy environments.
Applications
- Pressure transmitter measurement
- Level transmitter measurement
- Flow transmitter measurement
- Temperature transmitter measurement
- Position and displacement transmitter measurement
- Load and force transmitter measurement
- Interfacing passive (2-wire) 4-20 mA industrial sensors
Features
- Ten 4-20 mA current-loop input channels
- 12-bit measurement resolution across the 4-20 mA range
- Configurable measurement filtering for stable readings in noisy environments
- Protected 16 VDC built in power supply (use with passive sensors)
- Wire break detection on each input
