Omron, GX-AD0471 / DA0271 Series

The input/output range can be easily changed by the setting with the switch.
Detachable screw terminal block facilitates the maintenance.
Moving average calculation function. Settings within the range of 100us-64ms. (For input only.)
Disconnection detection function. (For input only and for usage with 1-5V or 4-20mA ranges.)
Selectable node address setting methods: setting with rotary switch and with tool software. When setting the nodes with rotary switch, setting is easy and node identification becomes possible for maintenance.
