Specifications subject to change without notice.

16 Relays
16-ch Wide-Range inputs
IA Daisy-chain Series

Intelligent Appliance

The IA-3126-2 is an indutrial intelligent 16-ch Relay Control Board, with 16-ch Digital Input and multi-drop operation

capability, in the original IA-3131 foot print.

The IA-3126-2 is an Industrial grade relay controller, easy operated, supported by a simple, yet, powerful command set.

Rich software support, including open source code samples and setting utility makes it fast and easy adaptable device.

The IA-3126S is an inductive load supporting version of the original IA-3126 Controller, that includ voltage suppressors

across its Relay contacts. This version is limited to 56VDC and 40VAC load voltage operation range.
