- Basic CPU module including the small housing for the PCA14 system
- Supports four plug-in I/O modules and up to 32 I/O addresses in PCA141
- Provides battery-backed user data and a 20 mA serial current-loop interface
SAIA PCA1.M41 forms the processor and housing foundation of the compact PCA14 programmable-controller system.
The official PCA1 hardware manual documents its processor, memory organization, I/O capacity, serial connection, backup supply, and front-panel controls.
Replacement requires preserving the complete application and installed I/O arrangement rather than treating the housing as an independent passive chassis.
Availability, condition, price, and shipping time for SAIA PCA1.M41 are confirmed during quotation.
