Applications

As a stand-alone product, these 32-bit controllers, with their 32-bit wide memory, offer the performance needed for those applications requiring real-time communications using multiple protocols and short program loop times. The controllers can be used in either master or slave configurations. Real-time communications using industry standard Modbus protocols simplify integration with SCADA software, man machine interfaces (MMIs), distributed control systems (DCSs), intelligent instrumentation and remote I/O control applications.

With their compact footprint and high level of integration, the PLCs are a natural choice for applications where a large number of process I/O and/or control loops are required. As a cost effective solution, these products can be applied to demanding applications including compressor controls, multirun gas flow computation and electrical distribution. With a real-time clock calendar providing time of day operations and alarms, and a hardware watchdog timer protecting against application program failures, the controllers can be used in a wide range of critical processes. Having onboard Ethernet and four multifunctional serial ports, the controllers can also be used in high performance data concentration and network traffic management applications.

The SP32 series of PLCs are fabricated with conformal coatings, gold-plated machined sockets and zinc plated steel system components. Regardless of the specific need, the controllers can provide reliable and compact stand-alone performance in the hazardous environments so often found in SCADA applications.
