The Omron C200H-ID216 is a high-density DC Input Module belonging to the legendary C200H series PLC family (including C200HS, C200HE, C200HG, and C200HX).1
Because it is a “High-Density” module, it provides a large number of inputs in a single slot, making it ideal for large-scale machines with many sensors and switches where panel space is at a premium.
1. Key Specifications
The “ID” prefix indicates a DC Input, while the “216” indicates the specific density and voltage rating.
-
Input Points: 32 Points (This is a high-density module compared to the standard 8 or 16-point modules).2
-
Input Voltage: 24V DC.3
-
Input Current: Typical 4.1 mA per point.
-
Operating Voltage Range: 20.4V to 26.4V DC.
-
Input Impedance: 5.6 4$k\Omega$.5
2. Wiring and Connection
Unlike standard modules that use screw terminals, the C200H-ID216 uses a high-density connector (typically a 40-pin Fujitsu or similar connector) because 32 points plus common terminals cannot fit on a standard screw block.
-
Connector Type: 40-pin MIL-style connector.
-
Common Points: The 32 inputs are usually divided into two groups of 16, with shared common lines.
-
Wiring Options: Most users pair this module with a Pre-wired Cable and a Remote Terminal Block (like the XW2B series) to simplify wiring and maintenance.
3. Response Times
This module is designed for standard industrial logic but features built-in filtering to prevent “chatter” or noise from causing false triggers.
-
ON Delay: Max 1.5 ms.
-
OFF Delay: Max 1.5 ms.
4. Hardware Indicators
On the front of the module, you will find:
-
Status LEDs: There are 32 miniature LEDs, usually organized into two banks (A and B).
-
Switching: A small toggle switch on the front panel often allows you to choose which bank (0–15 or 16–31) the LEDs are currently displaying.
5. Technical Data Table
| Feature | Details |
| Model | C200H-ID216 |
| I/O Points | 32 |
| Rated Voltage | 24V DC |
| Logic Type | NPN/PNP Compatible (Depending on common wiring) |
| Internal Current Consumption | 100 mA (at 5V DC from backplane) |

6. Maintenance and Troubleshooting
-
Fuse: Note that high-density modules often do not have user-replaceable internal fuses for individual inputs; protection should be handled externally.
-
Compatibility: This module is compatible with C200H, C200HS, and all “Alpha” series racks (HE/HG/HX). It is not compatible with the very small CQM1 or the newer CJ1/CP1 series without specific adapters.
