At the 2005 SPS/IPC/Drives Schleicher unveiled the new XCx-micro mini-controller, expanding the bottom end of the fast XCx controller range. It is based on modules just 22.5 mm wide. The heart of an XCx-micro systems is the PLC module with CANbus interface (CANopen), two RS 232 interfaces and a maintenance-free battery for buffering the real-time clock and memory. The second module of the basic setup is a 24 V power pack that supplies the CPU and up to eight additional connected modules. The I/O modules are designed for classic enclosure operation with single-conductor connection. Thus you will find space for up to 14 24 V connections on each module. This compact and cost-effective PLC for small and medium-sized machines consequentially achieves – if we take the power supply into consideration – one of the highest channel densities of any control system in this market segment. The XCx-micro possesses a large memory, can be configured in any of the five languages of the IEC 61131-3 standard and is fully multi-tasking-capable. As well as the new digital and analog I/O modules you can also connect three-wire function modules – thermoelements or fast counters for example – from Schleicher’s familiar RIO range wirelessly to an XCx-micro using an adapter. |
