In the case of the ‘EDP300 Control Unit with EDP300 Remote
Sensor’ design, the components are supplied in two housings,
which together form one harmonized unit.
Housing 1 (EDP300 Control Unit) contains the electronics and
pneumatics along with the following optional modules (where
applicable):
• Analog position feedback
• Digital position feedback
• Emergency shutdown module
• Universal input
Housing 2 (EDP300 Remote Sensor) contains the position sensor
and is suitable for mounting on linear or rotary actuators.
If necessary, the following options can be installed if required:
• Optical position indicator
• Mechanical feedback contacts designed as proximity
switches or microswitches.
The housings of the EDP300 Control Unit and the EDP300
Remote Sensor are available in stainless steel as an option.
Cable specification
To connect the EDP300 Remote Sensor, a cable with the
following specifications needs to be used:
• 3-wire, cross-section 0.5 to 1.0 mm²
• Shielded, with at least 85 % coverage
• Temperature range up to at least 100 °C (212 °F)
The cable glands used must also be approved for a temperature
range up to at least 100 °C (212 °F). The cable glands require a
mounting for the shielding and strain relief for the cable in
addition.
ABB offers suited cables and cable glands with DNV_GL
certification for the EDP300 Remote Version.
