lead step motors. The MBC25081-06 can operate from -40°C to 85°C. The MBC25081-06 has an output
current range of 0.5 to 2.5 amps/phase and operates off 12VDC minimum to 24VDC maximum. The
inputs are capable of running from either open collector or TTL level logic outputs, or sourcing 24VDC
outputs from PLCs. The MBC25081-06 features resolutions from 200 - 1600 steps/revolution, providing
smooth rotary operation. The MBC25081-06 features include built in over temperature and short circuit
shut down, automatic 70% reduction in current after clock pulses stop being received, and status LED’s to
indicate power on (green LED) and clocks being received (yellow LED). The MBC25081-06 is a compact,
