The 170ADI34000 is a high-density discrete input base module developed by Schneider Electric SE for the Modicon Momentum PLC Platform. This 16-channel digital input module is engineered to capture 24 VDC field signals from industrial devices such as proximity sensors, limit switches, and operator pushbuttons.
Designed with distributed control architectures in mind, the 170ADI34000 can function either as local I/O or as remote I/O when paired with communication adapters supporting protocols such as Modbus TCP, PROFIBUS, or INTERBUS. Its compact modular design helps reduce cabinet space while maintaining reliable signal integrity in noisy industrial environments.

The 170ADI34000 is commonly deployed in:
Conveyor and material handling automation
Water and wastewater treatment plants
HVAC building automation systems
General machine sequence control
Its modular base architecture allows rapid replacement of communication adapters without rewiring field devices, improving maintenance efficiency in large automation installations.
Does this module require external field power?
Yes. A 24 VDC external supply is required for input signal loops, while internal logic power is supplied through the communication adapter or processor base.
Is it compatible with 2-wire sensors?
Yes, the module supports 2-wire and 3-wire 24 VDC sensors, provided the sensor leakage current does not exceed the module’s OFF-state threshold.
