Analog 4-20 mA Module

Analog I/O 4-20 mA Module

BM-A420-122x

The analog 4-20mA I/O module provides two 24-bit inputs and two 16-bit outputs. The I/O modules offer 2500 V r.m.s. isolation, with a wide operating temperature range and Class I Division 2 hazardous location rating, making them ideal for demanding industrial installations.

Connect them to the wireless I/O radios for point-to-point wire replacement applications, or to the RS485 I/O Extension module to add I/O to a Modbus network.

 

Used With:

Wireless I/O Radio Kit

Multi-Point Wireless I/O Radio Kit

Modbus RS485 I/O System

Características y Beneficios
