I/O system squeezes 20 channels into 12.5mm-wide modules

02 May, 2013

The Austrian automation company Sigmatek has developed a compact modular I/O system that fits up to 20 channels in a 12.5mm-wide module. The rail-mounting S-DIAS modules – which include safety versions ­– communicate using a real-time Ethernet system called Varan with a bus speed of 100Mbit/s. The I/O modules can be accessed within 1.12µs.

All data on the bus is backed up and, in the event of a fault, is repeated automatically in the same cycle. The system supports up to 64 I/O modules with up to 1,280 I/O per bus interface and an update time of less than 60µs.

No tools are needed to mount the modules, which use push-in connections. The modules and can be pre-assembled into blocks, minimising assembly and wiring times, and simplifying maintenance. Status LEDs are provided next to each channel, as well as a test point for the channel’s connector.

Safety modules with reaction times of a few milliseconds can be integrated seamlessly into the system. Sigmatek’s TÜV-certified S-DIAS safety system can be combined flexibly with standard modules, or used independently.

The S-DIAS series I/O can be combined existing Sigmatek I/O components. Existing modules include digital versions with 4, 8, or 20 digital inputs, and one with 12 2A digital outputs. More modules are being developed, including one with 16 short-circuit-proof 2A outputs, and another with ±10V analogue outputs. A 16-bit resolution input module with ±10V analogue inputs is planned, as is one with eight analogue inputs for thermal elements.
