DO-1 Isolated Relay Output NO/NC – 8-Channel I/O Module
 |
The unit provides 8 normally-open or normally closed relay circuits for controlling output loads. |
Features:
The DO-1 provides 8 normally-open or normally closed relay circuits for controlling output loads. Output channels are isolated from the other channels and each pair of channels has a separate common terminal. The relay outputs can control a wide range of user-supplied load devices, such as: motor starters, solenoids and indicators. The user must supply the AC or DC power to operate the field devices connected to this module. Internal fuses protect the relay contacts should ratings be exceeded.
The insert in the hinged cover of the terminal strip has circuit wiring information. Circuit identification information can be recorded on the outside surface of the insert. The outside left edge of the insert is color-coded red to indicate a high-voltage module.
