Description

The Moxa 45MR-1601 is a 16-channel digital input module for the ioThinx 4500 Series. It supports 24 VDC NPN wet and dry contact sensors and operates across a -20 to 60°C temperature range, making it suited to factory automation and industrial monitoring panels where many discrete signals need to be gathered in a compact footprint.

The module offers an event counter function on the first four channels with a 1 kHz counting frequency, software-configurable digital filtering, and 3k VDC isolation. Spring-type Euroblock terminals allow tool-free wiring, and DIN-rail mounting keeps installation simple in standard control cabinets.

Features

- Software-configurable digital filtering time interval
- Event counter function on the first 4 channels
- Spring-type Euroblock terminal for tool-free wiring
- Standard-temperature model; the -T variant (45MR-1601-T) covers -40 to 75°C
