Configured for analog temperature input digitization in Omron CP1 PLC systems, the Omron CP1W-TS004 (CP1W I/O Expansion Unit) provides direct physical/electrical execution.

Module Designation & Model Structure

• CP1W: Expansion unit series for CP1 series compact programmable controllers.

• TS: Temperature sensor input module functional designation.

• 004: Model iteration code specifying 12-bit conversion resolution across 2 discrete analog input channels.

Electrical & Physical Specifications

Backplane Integration & Deterministic Scaling

The expansion module interfaces directly to the PLC CPU backplane bus cable to enable low-latency signal acquisition. Optimized internal bus protocols preserve high backplane bus communication velocity while maintaining CPU firmware flash compatibility and predictable I/O density scaling across expanded multi-module configurations.

Standard Delivery Content

• 1 x Omron CP1W-TS004 Expansion Module

• 1 x Bus Extension Connecting Cable Assembly

• 1 x Terminal Connector Cover

Installation & Wiring Guidelines

• DIN-Rail Mounting: Mount the expansion block onto a standard 35 mm DIN rail adjacent to the CPU unit. Engage the rear mounting clip until an audible latching sound confirms physical security.

• Bus Connection Procedure: Connect the expansion ribbon cable directly into the expansion port of the preceding CPU or expansion module prior to applying system power.

• Signal Shielding: Ground all sensor wire shielding at a single point to prevent electrical noise interference from corrupting 12-bit analog input conversion values.

Technical Support FAQ

• What is the required procedure for connecting the unit to the CPU backplane?

  Power off the main CPU unit completely before plugging the integrated expansion ribbon connector into the adjacent CPU bus port.

• Is hot-swapping allowed for this expansion unit while the PLC is powered?

  No, hot-swapping is strictly prohibited; removing or attaching expansion units under power will result in backplane fault errors.

• How does the CPU supply power to the expansion module?

  Operating power is drawn directly from the main CPU base unit via the ribbon expansion interconnect cable.

• What digital resolution does the unit provide for input processing?

  The onboard analog-to-digital converter processes physical input signals into 12-bit digital values across both input channels.

• How many total analog channels are supported by a single unit?

  The module provides 2 dedicated, independent analog input channels for sensor signal digitization.

• What action should be taken if an I/O bus error occurs on the module?

  Verify physical alignment of the expansion cable, clean edge connector contacts, and power cycle the host PLC controller.

• What gauge wiring is recommended for the terminal block connections?

  Use twisted-pair copper conductors ranging from 0.5 mm sq to 1.25 mm sq to ensure reliable terminal clamping.

• Can multiple CP1W expansion modules be daisy-chained together?

  Yes, modules attach sequentially up to the maximum expansion limit defined by the host CPU model specifications.
