Product Overview
The WBI334U01-S uses electromagnetic isolation to convert DC current into a load-independent current signal. The manufacturer specifies a selectable nominal input within the documented 0-1mA through 0-5A span; the exact nominal input must be confirmed for each order.
Key Features
- Exact WBI334U01-S DC current-transducer model
- 0-20mA or 4-20mA DC output
- 12V DC or 24V DC auxiliary-supply options
- 150ms supplier-listed response time
- 35mm DIN-rail installation

Applications
The supporting image shows a general industrial cabinet environment and does not depict a verified WBI334U01-S installation.

Industrial DC current monitoring
Condition a verified unidirectional DC current input for a compatible 0-20mA or 4-20mA receiving interface.
Control-cabinet signal interfaces
Use the DIN-rail format in measurement and control cabinets after confirming nominal input, supply and load conditions.
Information to Confirm for Selection
Provide the required nominal DC input, 0-20mA or 4-20mA output, 12V or 24V DC auxiliary supply, receiving-device load, quantity and application. Confirm the exact dimensional and terminal drawing before wiring. Do not select this product as a bidirectional sensor or protection device.
FAQ
Which input current should be ordered?
The manufacturer states a nominal input span from DC 0-1mA through 0-5A but does not enumerate every order code. State the required nominal input for supplier confirmation.
Are input current, output and auxiliary supply the same field?
No. They are separate selection fields. Confirm all three before quotation.
Is bidirectional current measurement verified?
No. The manual shows I+ and I- with a zero-to-positive DC input range. This page does not claim bipolar measurement.
