Standby batteries are used to supply power for the real-time clock upon power failure. Under normal temperature, the retention period of the real-time clock upon power failure is not less than 180 days.Number of Connectable Expansion Modules15; regardless of typesCOM Port2, RS232 or RS485;Supported working modes: Programming, Modbus-RTU (master/slave), Free protocolEquipment Connected with COM PortRS232/RS485: PC (for programming), third-party HMI panel, third-party serial communication equipment (for example, instruments, bar code reader, etc.)Input Power SupplyAC85 265VSensor Load Power SupplyDC24V, max. 500 mADimensions (L*W*H)200X114X70mm
