Optically Isolated Discrete Input Module

Features

• 11 channels of optically isolated digital input for industrial and equipment control applications: Volt-free contacts NO/NC, DC Voltage 0..24V digital

• Individually configurable direct/reverse on delay timing

• Real-time data acquisition, sample period could be set from 0.1s to 2s each channel

• Protection against power supply transients and reverse wiring avoids common hardware failures

• Low power consumption

• Compact design, DIN rail mounting

• Configurable standard firmware supplied pre-loaded, support for custom program development available

Overview

Discrete Input Module (61021) is designed based on high performance LonWorks Control Module (52004), could be monitored and controlled with communications over a LonWorks network.

The 11 signal-isolated digital inputs could be used for a variety of functions, such as alarm inputs, switch inputs, occupancy sensor inputs, or any other dry contact input.

A 32kb programmable flash memory provides storage for application programs and data.
