Hi, Dear! Welcome to our online store...
DSA-DO switching output safety barrier
· 1 in 1 out, 2 in 2 out. 12V/45mA intrinsically safe output, suitable for intrinsically safe equipment such as solenoid valves and alarms that drive dangerous areas. Open circuit voltage 22~26V. Current limit is 45mA. Terminal supply or DIN rail power supply is available.
· DSA-DO digital output safety barrier is suitable for driving the safety zone's power supply through switch control or logic level signal to drive on-site intrinsically safe equipment in the danger zone, such as solenoid valves, alarms and other intrinsic safety equipment.
· Output intrinsically safe signal: 45mA/12V (output voltage ≥12V when output current is 45mA
· This product requires a separate DC power supply. Power-input-output and isolation between channels.
