The Bluebirds have also announced that chartered accountant Ken Choo, whose most recent employment was with Berjaya Hotels and Resorts in London, will join the club as general manager.
"It's with great pride that I held the office at Cardiff City, but feel now is the right time to move on, allowing the club time to make adjustments over the summer before another important season," Lim told the club's official website.
"I'm honoured to have represented the club during our historic promotion winning year and very much hope to once again see Cardiff City in the Premier League at the earliest opportunity."
Dalman added: "On behalf of the board of directors and all at Cardiff City I would like to place on record my thanks and appreciation to Simon for his valued contribution over the last 18 months.
"We are pleased to welcome Ken to Cardiff City in the role of general manager, adding a wealth of knowledge and experience as the club moves forward. Ken will be responsible for shaping the business, making us more efficient and getting the best out of our talented staff.
"Ken will also join the newly formed Executive Committee, alongside Ole Gunnar Solskj?r, Tan Sri Vincent Tan's representative and myself. The committee will openly discuss and agree all major decisions in the best interests of Cardiff City, which is a positive step for this club to take."
