EIM..M series of digital I/O expansion module is a remote control unit follows the format of MODBUS RTU communication rule, the main purposes are increasing I/O points for AIRTEK DDC. It works with any controller which has an EIMnet port. EIM..M uses 32-bit microprocessor core, transmission rate up to 38,400 bps. Theirs binary and pulse inputs have 5,000Vrms optical coupling isolates to block noise feature, Binary inputs accept dry contact or open collector signal, Pulse inputs accept the largest 100HZ signal. Their binary output is a 7A/250VAC/SPST relay dry contact, it can control facilities directly. The physical points of EIM can be directly converted to DDC's BI / BO points. Therefore, setting or transfer of these I/O points is not required. The controller can use these points directly. EIM..M makes the arrangement of control points flexible, save money, and helps to control all related control points in a single program. It is absolutely the best product for your building.
