G7F-AD2B

Description

A 4-channel, 12-bit A/D analog input module tailored for the MASTER-K120S CPU family; supports both voltage and current sensors and includes side slide-switch selection for V/I.

The Polar Energy Assessment:

The G7F-AD2B provides four analog input channels (voltage/current) with 12-bit conversion for MASTER-K120S PLCs. It includes per-module slide switches for voltage/current selection, photo-coupler isolation to the PLC supply, and a 2 ms/channel conversion rate. The module is optimized for MASTER-K120S firmware behavior and maps its A/D results into reserved registers for direct use by the CPU function blocks. Use it where you need compact, reliable analog acquisition on MASTER-K120S control racks.

Pros

• Designed specifically for MASTER-K120S; plug-and-play compatibility and register mapping.
• Good resolution and accuracy (12-bit, ±0.5% F.S.) for typical process and building sensors.
• Slide-switch V/I selection simplifies field wiring changes without software rework.

Limitations

• No per-channel galvanic isolation; channels are not isolated from each other.
• Some features (max module expansion, function block behavior) depend on CPU ROM/version; verify KGL-WIN / ROM compatibility.

Typical use cases

• MASTER-K120S based PLC installations: BAS sensor inputs, analog monitoring in small plants, flow/pressure/level acquisition where CPU-native mapping is preferred.
