This baseplate provides mechanical support and backplane connectivity for Series 90-30 modules. The GE IC693CHS391 expands the system by adding five I/O module slots. It distributes power and communication signals to all installed modules reliably. The baseplate mounts directly to the cabinet backpanel for secure installation. Its passive design ensures trouble-free operation without active electronic components.
Mechanical Dimensions and Construction Quality
The baseplate measures 370 mm in height, 120 mm in depth, and 60 mm in width. This spacious design accommodates up to five I/O or specialty modules comfortably. Weighing approximately 1.2 kg, the IC693CHS391 provides substantial structural stability. A heavy-gauge steel chassis offers excellent mechanical strength and vibration resistance. This chassis also includes integrated mounting flanges for straightforward cabinet installation.

Interface and Connectivity Features
Five 96-pin female DIN connectors provide the interface for each installed module. These connectors accept standard Series 90-30 modules without special adapters. The backplane bus distributes power and data signals between modules seamlessly. A dedicated power supply slot accepts the system power supply module. The baseplate also includes ground studs for proper system earthing. Cable management channels allow neat routing of field wiring alongside the baseplate.
Power Distribution Architecture
The GE IC693CHS391 distributes 5 VDC, ±15 VDC, and 24 VDC from the power supply. It provides these voltages to all five module slots via the backplane. The passive bus design includes separate power and signal layers. Each slot receives filtered power through dedicated decoupling capacitors. The baseplate does not require any external power connection itself. Its internal bus can handle up to 20 A total current capacity.
Internal Construction and Component Layout
This baseplate uses a four-layer printed circuit board for the backplane bus. The PCB includes dedicated power, ground, and signal planes for noise reduction. Five DIN connectors align precisely for easy module insertion and removal. The steel chassis includes card guides for each slot to align modules correctly. Assembly includes 64 decoupling capacitors across the power distribution network. The baseplate contains no active ICs, processors, or firmware components.
Environmental Performance and Certifications
This baseplate operates reliably from 0 °C to +60 °C in industrial environments. It also performs consistently in humidity conditions from 5% to 95% without condensation. The IC693CHS391 complies with UL 508, CSA, and CE certification standards. These approvals ensure safe integration into global industrial control systems.
