FAQ
FAQ
Q1. What is the main function of the 1794-OW8?
It is used to switch both AC and DC loads using mechanical relay contacts in industrial control systems.
Q2. How many output channels does it have?
It provides 8 isolated relay output channels.
Q3. What types of loads can it control?
It can control AC loads (up to 250 VAC) and DC loads (up to 30 VDC), depending on configuration.
Q4. What is the output type?
It uses Form A (normally open) electromechanical relay contacts.
Q5. Does it provide electrical isolation?
Yes, each channel is galvanically isolated through relays.
Q6. What is the switching speed?
Typical switching time is around 10 ms for ON/OFF transitions.
Q7. What is it commonly used for?
It is used for switching motors, contactors, solenoids, alarms, and general-purpose industrial loads.
Q8. What is the difference between OW8 and transistor output modules?
OW8 uses mechanical relays (slower but can switch AC/DC and higher voltages), while transistor modules are faster but limited to DC switching only.
