Frequently Asked Questions

• Q: What is the difference between sourcing and sinking outputs?
  A: Sinking outputs (like the 1790-T0V16X) connect the load to ground when active, while sourcing outputs connect the load to positive voltage.
• Q: What current can each output channel handle?
  A: Each output supports 0.5A maximum current with 4.0A maximum per common terminal group.
• Q: How many common groups does this module have?
  A: The module has two common groups, with eight outputs sharing each common terminal.
• Q: What voltage range does this module support?
  A: It operates with 10-28.8V DC field power (24V DC nominal).
• Q: Does the module provide visual status feedback?
  A: Yes, it includes sixteen green LEDs that indicate the status of each output channel.
• Q: How fast does the module switch outputs on and off?
  A: Switching occurs within 0.5ms maximum for turn-on and 1.0ms maximum for turn-off.
• Q: Is this module compatible with DeviceNet communication?
  A: Yes, the 1790-T0V16X is designed for DeviceNet networks with specified DeviceNet power requirements.
• Q: What type of isolation does the module provide?
  A: It features photocoupler isolation (1250V AC RMS) between the I/O circuits and logic circuits.
