GE Fanuc IC754VSI06STD-LH VersaMax Micro Discrete Input Module

In stock

Product Overview:
The GE Fanuc IC754VSI06STD-LH is a 6-channel discrete (digital) input module for the VersaMax Micro PLC platform. The “LH” suffix indicates a low-side (sinking) input configuration, meaning the module accepts signals where the field device switches the negative side of the circuit to ground. This module is used to read the status of switches, pushbuttons, proximity sensors, photoelectric sensors, and limit switches. It provides galvanic isolation between the field devices and the PLC logic, protecting the CPU from voltage spikes and ground loops.

Functional Features:
Sinking Input Configuration: Optimized for NPN-type sensors and devices that switch the ground side (0V) of the circuit.
6 Independent Channels: Each channel operates independently with its own filter and LED indicator.
Wide Voltage Range: Accepts 12V to 48V DC, making it compatible with a wide variety of sensor types without external power supplies.
Programmable Filter: Built-in digital debounce filter eliminates false triggering from mechanical switch bounce or electrical noise.
LED Status: Each channel has a green LED that illuminates when the input is ON (active).
Group Isolation: Inputs are grouped in sets of 3 with shared common terminals, simplifying wiring.
