The APS300 is the main control module in esitron-electronic's APS (Automation + Positioning + System) family — a compact DIN-rail PLC that combines full IEC 61131-3 programmability with integrated motion control. With 20 digital inputs, 12 digital outputs, 4 analog inputs, and 2 analog outputs onboard, it handles discrete automation and analog signal processing without additional I/O modules for most single-station applications. The CoDeSys runtime supports standard PLC languages plus positioning function blocks for axis control.

How does the APS300 handle motion and I/O expansion?

A galvanically isolated CANopen master port on the front RJ45 connector manages up to 127 servo axes and decentralised CAN I/O modules — scaling the system from a single PLC to a multi-axis production cell controller. Up to seven direct-mount expansion modules snap onto the side of the APS300: the APS114 (8 DI + 8 DO), APS133 (6 analog differential inputs + 4 analog outputs), and APS171 (single-axis position controller with ±10 V output). An optional Profibus-DP slave interface and Ethernet programming port are available.

What operator terminals are compatible?

esitron-electronic offers a range of matched operator terminals — from the HBG10 handheld unit with emergency stop and optional handwheel to VTxx series touch panels (4 to 12.1 inches) with recipe memory, to BT20/BT24 text displays with function keys. Any terminal connects via Modbus, and the real-time clock with 6-week power reserve maintains time-stamped event logs through power cycles.
