The EX100.1 and EX200 Control Panels are microprocessor based units designed primarily for small to medium sized explosion protection applications. A wall-mounted NEMA 4 (IP66/IP55) enclosure is standard to provide superior protection against dust and weather infiltration (NEMA 4X and NEMA 7/9 enclosures are also available). System status is visible through a scratch-resistant polycarbonate window. Electrical terminations are protected behind a full face cover panel. Terminal access has been carefully designed for ease of installation. The microprocessor design provides comprehensive self-checking routines during start-up and during operation to provide the highest level of reliability. The control panel also provides flexibility in field wiring configurations and detection logic.
