Why Choose the ABB DA502 1SAP250800R0001 Digital/Analogue I/O Module?
The ABB 1SAP250800R0001, type designation DA502, is an S500 digital and analogue I/O module designed for ABB AC500 automation systems. It combines digital switching and analogue signal processing in a single compact module, providing 16 digital outputs, 8 configurable digital input/output channels, 4 analogue inputs and 2 analogue outputs.
The digital channels operate at 24 V DC, with digital outputs rated at up to 0.5 A. The four analogue inputs support voltage, current and RTD signals, while the two analogue outputs support voltage and current signals. Analogue conversion provides 12-bit plus sign resolution, making the DA502 suitable for mixed measurement and control applications.
Designed for the modular ABB AC500 / S500 platform, the DA502 provides a space-efficient way to combine multiple field signal types within one I/O station. It can be used with TU515 or TU516 terminal units and is well suited to machine automation, process control, building automation and distributed industrial control applications.
