Schneider Electric CP-8391-716-0-01 NSNBC01 Compact Programmable Controller

Schneider Electric CP-8391-716-0-01 NSNBC01 Compact Programmable Controller is a compact solid‑state actuator drive that accepts a current input (mAdc) from a controller to position a line‑voltage damper actuator. It is designed for use with line‑voltage actuators that have an internal transformer and is powered from 120 or 240 VAC (±10%, 50/60 Hz). Typical actuators include MP‑361, MP‑371, MP‑381, and MP‑382, with 24 V actuators not available for this model. The drive provides an adjustable input range: span 4 to 16 mAdc (factory default 16 mAdc) and a start point adjustable from 2 to 16 mAdc (factory default 4 mAdc). The actuator rotates clockwise on an increasing mAdc signal between Black (−) and Red (+); to rotate counterclockwise, reverse the Black/Blue and White/Blue leads and swap the Orange/Yellow leads. Power consumption is 7 VA at 120/240 VAC, 50/60 Hz. In typical installations, a controller with up to 20 mA output can drive up to three CP‑8391‑716 actuator drives. This configuration is documented in Schneider Electric’s wiring and operation guides for CP‑8391‑716, and the NSNBC01 suffix denotes this particular variant of CP‑8391‑716‑0‑01.
