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.
