GE IC200CHS112A Relay-Style Interposing I/O Terminal

Technical Specifications

Physical Build and Component Layout

This IC200CHS112A terminal measures 5.5 inches in length. Its width reaches 4.0 inches with a height of 2.1 inches. The total weight comes to approximately 0.92 pounds. Manufacturers placed 58 discrete components on this PCB. These components include relays, resistors, flyback diodes, and LEDs. The board uses a compact two-layer design for easy integration.

Relay Configuration and Signal Interposing

IC200CHS112A provides twelve independent interposing relay terminals. Each relay offers single-pole double-throw (SPDT) contact configuration. The contacts handle up to 3 amps at 250V AC. Alternatively, they handle 3 amps at 30V DC comfortably. Coil voltage requires 24V DC with a tolerance of ±10%. Typical response time reaches 8 milliseconds from coil energization. Therefore, this module isolates field devices from sensitive PLC inputs.

Energy Storage and Power Management

The interposing terminal integrates one 1000µF electrolytic capacitor. This capacitor absorbs voltage spikes from relay coil switching. Additionally, each relay includes a flyback diode for back-EMF suppression. LED indicators show the status of every channel individually. You can easily troubleshoot field wiring with these visual indicators.

Application Scenarios and Wiring Benefits

You will use this module between PLC outputs and heavy loads. It protects your controller from high inrush currents or voltage spikes. The IC200CHS112A operates reliably from -20°C to 60°C ambient. Common applications include motor starter interfacing and valve control. It also suits signal conversion between different voltage systems. Consequently, this terminal extends the life of your expensive PLC hardware.
