Description
EM11 expansion memory — Analog/Digital I/O
Siemens (SIMADYN D) · EM11 expansion memory · 6DD1640-0AC0
Description
The EM11 is an input/output expansion module for SIMADYN D (16-bit), providing a mix of digital and analog channels directly on the L/C bus: 8 binary outputs, 4 analog inputs, 4 interrupt-capable analog inputs, and 2 analog outputs with pulse-sensing capability. Despite the inventory label "expansion memory," it is an I/O module, not a memory-expansion card.
