Connecting control outputs (outputs 1, 2)
WARNING
Before removing, mounting, or wiring the DCP301, be sure to turn off the
power to the DCP301 and all connected devices.
Failure to do so might cause electric shock.

Minimum switching current: 100mA
Handling Precautions
When switching small currents, connect a bleeder resistor to allow current flow of
the minimum relay switching input (100mA min.).

Handling Precautions
4 to 20mAdc and 0 to 20mAdc can be selected in setup data C 9 0.
■ Position-proportional output (2G)
Connect as follows paying attention to the switching direction.

Handling Precautions
• The life of internal relays is limited.
Avoid setting the PID constant in such a way that results in excessive repeated
ON/OFF switching.
• When using a 100/200Vac motor, pay attention to rush current and the contact
rating. If necessary, provide an external auxiliary relay.
• Separate the wiring for motor terminals (11) (12) (13) and feedback resistor
terminals (14) (15) (16).
(Do not wire the leads in the same duct or use 6-core cable. Doing so might
result in faulty controller operation caused by electrical noise when the motor is
started up.)
• When controlling without motor feedback with variable parameter M .-Cset to
“2”, terminals (14) (15) (16) need not be connected.
