Description

The Moxa 45MR-1600 is a 16-channel digital input module for the ioThinx 4500 Series modular advanced controllers and I/O. It accepts 24 VDC PNP wet contact and dry contact sensors, making it well suited to industrial automation panels that need to add compact, DIN-rail mounted digital input capacity. The standard temperature rating of -20 to 60°C suits typical control cabinet environments.

The first four channels can operate as standard digital inputs or as event counters at up to 1 kHz, while software-configurable digital filtering helps reject noisy signals. Spring-type Euroblock terminals allow tool-free wiring and removal, and built-in LED indicators show the status of each I/O channel at a glance.

Features

- Tool-free installation and removal
- Spring-type Euroblock terminals for fast wiring
- Built-in LED indicators for I/O channels
- DI or event counter mode on the first 4 channels
- Software-configurable digital filtering time interval
