Product Details:

The 16305-41-4 is an MBI ISA slot M-Bus interface module of Moore APACS+ series under Siemens. It is designed to be installed inside the ISA expansion slot of industrial control workstations, acting as the communication bridge between the IPC host and APACS+ M-Bus control network. It converts ISA parallel bus signals into dedicated M-Bus protocol data, realizing bidirectional transmission of real-time process values, alarm messages and control parameters between upper monitoring stations and ACMx control racks.

This module integrates optocoupler isolation and surge protection circuits, which can filter abnormal interference on the M-Bus network and prevent grid surge signals from damaging the industrial computer motherboard. The suffix 1-4 defines its fixed communication baud rate, pin assignment and hardware revision. It cannot be replaced directly by other 16305 interface modules with different suffix codes, and it relies on the ISA bus of compatible industrial computer for power supply and data interaction, it cannot run independently without matched IPC host.

The PCB board adopts conformal coating to resist dust, condensation and light corrosive vapors in refinery and chemical central control rooms. The status LEDs on the card edge display transmit activity, receive signal and module fault warning for convenient on-site inspection.

Most stocked units are surplus and fully tested cards recovered from decommissioned APACS SCADA workstations. Before installation, technicians need to configure ISA interrupt and memory resource of the industrial computer, and match the baud rate and station address of the M-Bus network. Incorrect network parameters will cause communication failure between workstation and control racks.

Industry Applications: Applied in petrochemical central monitoring rooms, gas metering management systems, boiler SCADA platforms and water treatment control centers for data interconnection between IPC host and APACS+ M-Bus network.

Note: Confirm ISA host resource allocation and suffix M-Bus communication parameter before ordering
