Omron C200H-ID217 | SYSMAC C200H 64-Channel 24V DC Input Module — Screw Terminal / Rack Mount / Discontinued

64 Digital Inputs in One C200H Module

The C200H-ID217 is a 64-channel 24V DC digital input module for Omron's SYSMAC C200H PLC platform — the generation of modular Omron PLCs that built the installed base across machine tool, packaging, and general automation applications through the 1990s and into the 2000s. Sixty-four input channels from a single module means a fully populated C200H rack handles substantial machine I/O from a compact number of slots.

Each input channel accepts a 24V DC signal from sensors, switches, pushbuttons, and relay contacts in the field. At 4.1A total input current, the module provides robust signal reception across all 64 channels simultaneously. Screw terminal connection provides the direct, secure field wiring interface that C200H racks used throughout the platform's production life.

The C200H-ID217 is confirmed discontinued. C200H machines that remain in production depend on the aftermarket for this module — tested surplus and exchange units are the available replacement path.

Key Specifications

C200H Platform Context

The SYSMAC C200H series was a foundational Omron platform — it predated the CS1 generation and established the modular PLC architecture that Omron built on across subsequent product families. The C200H, C200HX, C200HG, and C200HE variants share a compatible I/O rack and module ecosystem, meaning C200H-ID217 modules can serve any of these controller variants within a compatible rack configuration.

For machines still running C200H controllers in production, maintaining a spare input module is a practical reliability measure. The C200H I/O bus is not forward-compatible with CS1 or CJ1 I/O modules — there is no direct plug-in substitute from a newer Omron platform.

FAQ

Q1: What PLC models are compatible with the C200H-ID217?

The C200H-ID217 mounts in the I/O racks compatible with SYSMAC C200H, C200HX, C200HG, and C200HE controllers. These variants share a common I/O bus and I/O module format. Verify the specific rack type in the installed machine against Omron's C200H system configuration documentation before ordering a replacement module.

Q2: The machine shows an I/O fault on the C200H rack. How is the input module confirmed as the cause?

Check the C200H error indicators — the CPU and I/O modules each carry fault indicators. If the I/O rack bus error indicator is active, check all module seating in the rack first. An input module fault specific to one module position manifests as incorrect input readings or missing inputs at the programmed input addresses. Swap testing with a known-good C200H-ID217 is the definitive diagnostic step.

Q3: Can the C200H-ID217 be used in a CS1 or CJ1 rack?

No. The C200H I/O bus is a different physical and electrical format from the CS1 and CJ1 backplane bus. C200H modules are not physically compatible with CS1 or CJ1 racks, and vice versa. Machines running C200H must use C200H-compatible modules.

Q4: Where is the C200H-ID217 sourced after discontinuation?

Through the SYSMAC C200H aftermarket — Omron CNC and PLC parts specialists, industrial automation surplus dealers, and exchange services holding tested C200H module stock. Confirm C200H-ID217 specifically from the installed module's label. Adjacent C200H input modules differ in channel count, input voltage, or current specifications.

Q5: How are the 64 input channels addressed in the C200H programme?

The C200H allocates I/O words to each module slot in the rack during system configuration. A 64-channel input module occupies four I/O words (64 bits = 4 × 16-bit words). The specific word addresses depend on the module's slot position in the rack and the CPU's I/O table configuration. Replacing the module in the same slot position preserves the existing I/O address allocation without programme changes.
