Model Explanation

51304518: Basic material code for APM control card; -150: Hardware version with conformal coating for protection against moisture, dust, and chemicals; Belongs to UCN APM main control series R400 firmware version. Technical Specifications

Built-in dedicated computing processor; Backplane 5VDC power supply; Net weight of the entire machine is approximately 850g; Operating temperature: -25℃ to +70℃; Humidity: 5% to 95% without condensation; UCN bus rate: 500Kbps; Full board three-proof insulation coating, resistant to humid and corrosive conditions; CE and UL industrial certifications.

Interface and communication configuration

Gold finger connectors on the rear side are plugged into the UCN rack backplane; Built-in UCN bus link docking system network; Front-end is equipped with a dedicated FTA terminal board for connecting I/O signals; Panel RUN, COM, and FAULT status indicator lights, indicating running, communication, and fault status. Core function

Carry out continuous PID regulation, switch quantity interlock logic, and equipment sequence start-stop control; manage data interaction among the AI/AO/DI/DO sub-cards of this rack; perform hardware fault self-check and issue pop-up alarms on the upper computer; support hot-swappable UCN rack while powered on; automatically and without disturbance shut down the faulty unit when redundant APM configuration is adopted. Applicable scenarios

Replacement of APM controllers in old oil refining, chemical, and thermal power plant devices of the TDC300 system, and replacement of old DCS spare parts.

Operation and maintenance instructions

Single-point grounding of the cabinet, separate routing of signal shielded cables away from high-power power cables; quarterly inspection of panel indicator lights and backplane gold finger cleanliness; the third defense version does not require additional spraying for protection, and the circuit boards in humid areas should be blown to remove dust for half a year; before installing the spare parts, check the firmware version and synchronously download the control program.
