The BEMAC UST-205-D is a high-quality, double-sided printed circuit board (control board) assembly designed for reliable performance in industrial control systems. Fully populated with durable through-hole components, this board is engineered to handle demanding operational environments. It integrates essential electronic components including DIP ICs, relays, optocouplers, precise resistors, and electrolytic capacitors to ensure stable signal processing and power management. For accurate system calibration, the board features integrated trimmer potentiometers (VR1 and VR2), while onboard LED indicators allow for quick and easy real-time status monitoring. Secure and seamless system integration is guaranteed through its robust green terminal blocks and edge card connector. The board is easily identifiable by its authentic silkscreen markings, displaying UST-205-D and NO.1308E.
