Product Overview

The OMRON C500-ID219 (also designated 3G2A5-ID219) is a high-density DC input unit for the C500 series SYSMAC programmable logic controller (PLC) system. This input module provides 64 discrete input points, enabling the connection of field devices such as limit switches, proximity sensors, pushbuttons, and photoelectric sensors directly to the PLC system for monitoring and control applications. The C500-ID219 is designed for mounting on the C500 series backplane and is compatible with the full range of C500 CPU units and expansion racks.

The module operates on 24 VDC with a nominal input current of 7 mA per point, providing reliable signal detection across industrial switching devices. Inputs are considered ON when the applied voltage reaches a minimum of DC16.0 V, and OFF when the voltage falls below a maximum of DC5.0 V, ensuring proper state discrimination even in noisy environments. The module features a fast response time of 1.5 ms, enabling detection of high-speed input events.

Technical Specifications

Key Features

• 64 input points per module provide high-density discrete input capability, maximizing I/O capacity per rack slot.

• 24 VDC operation with 7 mA input current offers compatibility with standard industrial sensor and switch outputs.

• Precise ON threshold of DC16.0 V minimum ensures reliable detection of valid input signals despite voltage variations.

• OFF threshold of DC5.0 V maximum provides noise immunity and prevents false triggering from leakage currents.

• 1.5 ms response time enables monitoring of high-speed machine operations and dynamic process events.

• Fully compatible with C500 series CPU units and expansion racks for integration into existing installations.

• Backplane mounting eliminates external wiring between I/O cards and controller.

Applications

The OMRON C500-ID219 input unit is deployed in industrial automation systems where monitoring of discrete field devices is required. In manufacturing applications, the module receives signals from limit switches on positioning mechanisms, proximity sensors for part detection, pushbuttons on operator stations, and photoelectric sensors for product presence detection. The module's 64-point density makes it particularly suitable for systems with high input counts, reducing rack space requirements compared to lower-density modules.

Typical applications include automated assembly lines, packaging machinery, material handling systems, and process control installations where many sensors must be monitored simultaneously. The fast response time supports applications involving high-speed part counting, rotary encoder input (non-pulse type), and high-frequency switching detection.
