Frequently asked questions
What is the panel cutout size for the E5EC-QX4A5M-009?
The panel cutout is rectangular, 92.00mm x 45.00mm. This is different from the square 45mm x 45mm cutout of the E5CC series.
Can I use an E5CC-RX3A5M-003 as a substitute for this E5EC?
Not without panel rework and rewiring. The E5CC uses a square 45x45mm cutout, has four relay outputs only (no voltage output for SSR), lacks the Event Input, and has a two-row dual-color display instead of three-row tri-color.
What communications protocols does it support?
It has RS-485 with CompoWay/F and Modbus protocols.
