WARNING
4-8 Connecting control outputs (outputs 1, 2)
Before wiring, or removing/mounting the DCP301, be sure to turn the power
OFF. Failure to do so might cause electric shock.

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

• 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 .-C set to
“2”, terminals (14) (15) (16) need not be connected.
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.
