By supporting the standard MODBUS protocol, this advanced controller enables the seamless interconnection of up to 32 units, allowing central upper computers to perform remote reading, real-time monitoring, and quick configuration. Crucially, the SP-15 series retains 1-channel traditional switch output (NPN or PNP), ensuring comprehensive backward compatibility for local debugging and immediate threshold triggering in non-networked environments.
Features native RS485 integration supporting up to 32 units in a single daisy-chain connection. Simplifies industrial networking, data acquisition, and centralized parameter setting.
Uniquely retains 1-channel traditional discrete switch output alongside the communication bus, ensuring flawless operation and manual debugging during network downtimes or system transitions.
Incorporates exclusive algorithms for ultra-fast switch output response and integrated high-speed leak detection functions, pushing the limits of automated production efficiency.
Designed specifically for communication-heavy environments, the SP-15 series selection process focuses on defining your local switching preference alongside standard networking parameters:
