The DO-5 provides 16 output circuits for controlling the TEL REL 00x relay board. Power for the
external relay circuits is provided by the module from the +12 VDC bus on the backplane. A maximum
of three pairs of DO-5 modules and TEL REL 00x relay boards can be used per PS-xx power supply.
Additional pairs of DO-5 modules and TEL REL 00x relay boards can be used if the TEL REL 00x
relay boards are powered by an external source.
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.
