PSH2204R is a 2-phase RS485 open-loop driver featuring 32-bit DSP technology for low noise and vibration. It supports MODBUS-RTU protocol, position and speed control, and multi-segment positioning. The driver offers 4 optically isolated programmable inputs, 2 outputs, smooth current control up to 1.5 A, DC24–36 V input, and protection against overvoltage, undervoltage, and overcurrent. Up to 30 drives can be controlled via RS-485 bus.
