Picture Feature I.CH supply ODM service, this CI 243 Parallel Mirco Stepper Motor Controller is a customized motion control unit for monitoring and servo actuator of water flow etc industries. Micro Size, 16mm*24mm*2.5mm Embedded stepping pulse generator, adjustable frequency ON/OFF, Reset, Direction 3-wire control 10-35V DC, 2A adjustable phase current, 16 micro-stepping TTL Logic control Description CI243-2A is a high performance stepper motor controller that features micro miniature size and 2A max phase current. The size is only 16mm*24mm*2.5mm. Onboard 555 timer based stepping pulse generator unit eliminates the need for external pulse source. The pulse frequency is adjusted through an onboard potentiometer. Once the frequency is set, user only needs 2 signals to control the motor: on/off, direction. The Reset signal input can put the controller into sleep to maximum the power saving. If not needed, leave it open. We also offer quick engineering design service to satisfy the needs of single power supply, different micro-stepping options, photo coupler isolation and embedded control system, etc. MINIATURE DRIVER – Parallel CI243-2A Typical Diagram
