Comparison with Series Models (Simplified)

50R (1SBP260050R1001): 8DI / 6 relay outputs (2A/250VAC)

51R (1SBP260051R1001): 8DI pure input type, no output

52R (1SBP260052R1001): 8DI / 6DO transistors 0.5A

54R (1SBP260054R1001): 8DI / 6DO transistors 1A (enhanced)

56R (1SBP260056R1001): 8DI / 6DO transistors 1A (high configuration / long-term load optimization)

Selection Suggestions

52R: Ordinary low-load (indicator lights, small relays)

54R: Common solenoids, relays

56R: High-frequency / long-term 1A load, high ambient temperature, require higher margin
