Relay Output Wiring Methods
The D0–06AR and the D0–06DR models feature relay outputs. Relays are best for the
following applications:
• Loads that require higher currents than the solid-state DL06 outputs can deliver
• Cost-sensitive applications
• Some output channels need isolation from other outputs (such as when some loads require AC
while others require DC)
Some applications in which NOT to use relays:
• Loads that require currents under 10mA
• Loads which must be switched at high speed and duty cycle
This section presents various ways to wire relay outputs to the loads. The relay output DL06s
have sixteen normally-open SPST relays available. They are organized with four relays per
common. The figure below shows the relays and the internal wiring of the PLC. Note that each
group is isolated from the other group of outputs.
In the circuit below, all loads use the same AC power supply which powers the DL06 PLC. In
this example, all commons are connected together.
In the circuit on the following page, loads for Y0 – Y3 use the same AC power supply which
powers the DL06 PLC. Loads for Y4 – Y7 use a separate DC supply. In this example, the
commons are separated according to which supply powers the associated load.
