The BIK 121 delivers regulated DC power inside Schneider’s industrial control hardware range as a dedicated supply module. This unit measures roughly 7.9 inches long, 2.4 inches wide, and 4.7 inches high. Moreover, it weighs about 1.6 pounds, which suits standard DIN rail installation. Engineers specify the BIK 121 when they need stable rail voltages for controllers and field devices.
Technical Specifications and Interface Details
The module converts AC mains input into regulated DC output for control circuits. Specifically, it supplies 24 VDC at a defined current rating for connected loads. Additionally, screw terminals accept field wiring without special tools. Front-panel LEDs reveal output status and fault conditions during service.

Energy Storage and Output Stability
Internal capacitors on the BIK 121 provide substantial energy storage for smooth DC output. Consequently, the supply rides through brief mains dips without disturbing control circuits. This buffering also filters ripple that could affect sensitive measurement signals. The design therefore supports consistent performance across demanding plant conditions.
Installation and Compatibility Notes
Because the BIK 121 clips onto standard DIN rail, technicians finish installation quickly. They should verify mains voltage before they energize the supply. Furthermore, the module integrates smoothly with existing Schneider control hardware. Always store spare units in anti-static packaging to protect sensitive components.
