Description

Product Description

The IC200MDL243 is a 120 VAC discrete input module from GE Fanuc (Emerson), developed for the VersaMax I/O platform. It is intended for interfacing AC field signals with PLC systems, offering per-channel isolation to ensure stable signal acquisition in electrically noisy environments.

Each input channel is independently isolated and includes its own return path, which minimizes cross-channel interference and improves signal integrity. The module is suitable for applications involving AC-powered devices such as pushbuttons, limit switches, and relay contacts.

Input Channel Configuration

• Total input points: 16

• Input type: AC discrete, positive logic

• Input wiring: Individual return per channel

• Signal type: 120 VAC field inputs

This design allows accurate monitoring of independent AC signals without shared commons, reducing the risk of wiring-related faults.

Electrical Characteristics

• Nominal input voltage: 120 VAC

• Operating voltage range: 0 to 132 VAC (47–63 Hz)

• ON state:

• Voltage range: 70 to 132 VAC

• Minimum current: 5 mA

• OFF state:

• Voltage range: 0 to 20 VAC

• Maximum current: 2.5 mA

• Input impedance:

• ~8.6 kΩ at 60 Hz

• ~10.3 kΩ at 50 Hz

These parameters ensure compatibility with standard industrial AC control circuits.

Response Performance

• Turn-on delay: up to 1 AC cycle

• Turn-off delay: up to 2 AC cycles

The response timing is optimized for typical AC switching applications, balancing noise immunity and signal responsiveness.

Isolation Specifications

• Channel-to-channel isolation:

• 250 VAC continuous

• 1500 VAC for 1 minute

• Field-to-logic isolation:

• 250 VAC continuous

• 1500 VAC dielectric withstand

Full isolation across all input points enhances reliability in high-interference environments.

Power Requirements

• Backplane supply: 5 VDC

• Current consumption: up to 100 mA

• External power supply: not required

The module operates entirely from the VersaMax backplane, simplifying installation.

Diagnostics and Indicators

• 16 individual status LEDs (one per input)

• 1 module OK LED for backplane power indication

These indicators provide immediate visibility into input states and module health.

FAQ

Q: Does each input require a separate common terminal?
A: Yes. Each channel has its own return path, which improves isolation and reduces wiring interference.

Q: Can this module be used with DC signals?
A: No. It is specifically designed for AC input signals and should not be used with DC inputs.

Q: Is external power needed for operation?
A: No. The module is powered directly from the VersaMax backplane.
