RHD8000 / RHD16000 (Contrac)
ELECTRICAL ROTARY ACTUATOR | OI/RHD8000/16000-EN REV. D
… 6 Electrical connections
Electronic Unit EBN852 (Contrac)
Analog / Digital
Note
• The electrical connection is provided by a universal plug on the actuator and the screw terminals on the electronic unit.
• If you are using a separate heat supply, the heater must be protected with a 2 to 6 A medium time-lag fuse (e.g. NEOZED D01 E14).
