Technical & Operating Specifications

Industrial Bus Throughput & Deterministic Control

The embedded backplane bus communication velocity handles synchronous data refresh cycles across connected expansion modules, enabling flexible I/O density scaling up to 3 units. Internal execution microcode maintains absolute firmware flash compatibility with CX-Programmer routines while communicating deterministically across serial or host link network topologies.

Shipping Package Contents

• 1 x Omron CPM1A-40CDT1-D-V1 Processor Base Unit

Installation & Panel Wiring Practices

Base Hardware Mounting

Mount the unit onto a rigid 35 mm DIN rail or secure it to a grounded metal backpanel using M4 mounting screws through the integral corner mounting slots.

DC Power Circuit Wiring

Supply 20.4 to 26.4 VDC to the designated power terminals. Wire the functional ground terminal directly to the panel main earth bus using a short, heavy-gauge copper lead.

Output Load Wiring

Connect load devices to the 16 PNP sourcing transistor outputs, ensuring correct 24 VDC external power polarity is maintained across output commons to protect output drivers.
