B3624 Schneider BACnet Local Controller
BACnet Local Controller with 24 Universal Inputs, Line Fault Monitoring, DIN Rail Mount, IP20 Rating, DDC
Product Overview
The B3624 is a local controller from the Andover Continuum b3600 series, featuring twenty-four universal inputs in a single enclosure. This high-density design is ideal for applications requiring extensive monitoring with minimal command output. The controller accepts mixed signal types including resistance elements, voltage signals, and dry contacts, eliminating the need for signal separation. With 10-bit resolution for control and monitoring applications, it supports line fault monitoring to detect and report open or short circuit conditions. Programming is performed using the Andover Continuum toolset, and the device operates as a native BACnet Advanced Application Controller.

System Integration Notes
This high-density controller requires careful wiring discipline. All 24 loops must be properly identified, separated, and systematically tested. The line fault monitoring feature is only effective when loops are wired to distinguish open circuits from genuine alarm conditions. As a BACnet master on an MS/TP segment, device instance numbers, baud rate, and segment loading should be carefully planned. Proper segment termination and referencing are essential to prevent intermittent network faults. Programming should be backed up during commissioning.
Application Scenarios
- Plant Rooms: Monitoring pump statuses, valve positions, temperature sensors, and fault contacts from a centralized location
- Monitored Circuit Systems: Applications where loop continuity and integrity are critical, utilizing the line fault monitoring capability
- Commercial Buildings: Replacement part for maintaining Andover Continuum systems in floor or plant operations
- Institutional Facilities: Hospitals, universities, and transport buildings requiring extensive sensor acquisition without controller multiplication
- Industrial & Laboratory Facilities: Applications requiring local program execution continuity during supervisory layer unavailability
