Description

The 45MR-1601-T is a 16-channel digital input I/O module for the ioThinx 4500 Series, built for industrial edge connectivity. It supports 24 VDC NPN wet contact and dry contact sensors, and operates across a -40 to 75°C temperature range, making it suited to harsh cabinet and field installations.

The first four channels can also operate as event counters at up to 1 kHz, while digital filtering is software configurable to suit noisy signals. Spring-type Euroblock terminals allow tool-free wiring, and the compact DIN-rail mountable housing expands ioThinx 4500 Series advanced controllers and I/Os with additional digital input capacity.

Features

- Wide operating temperature range of -40 to 75°C for harsh industrial environments
- Spring-type Euroblock terminals for tool-free wiring
- Software-configurable digital filtering
- Supports both dry contact and NPN wet contact sensors
- Compact DIN-rail mountable design
