Overview
The Gould Modicon B552 is a Universal DC Output Module designed for legacy Modicon PLC systems. This discrete output card conditions four independently useable DC output signals, sharing common source and return connections to signals used internally in the controller. The B552 provides the capability of using discrete output voltages varying from 10-48VDC, making it suitable for industrial control applications requiring reliable discrete DC outputs.
Key Features
- Four independent DC output channels with shared common and return
- Supports 10-48VDC output voltage range
- Universal signal conditioning for discrete control applications
- Designed for Modicon 500 series and compatible legacy platforms
- Compact module format for standard slot mounting
Technical Specifications
