Phoenix IBS ST BK DIO 8/8/3-T

Core Performance & Industrial Application

The Phoenix Contact IBS ST BK DIO 8/8/3-T (order 2752411) is an INTERBUS-ST bus terminal module with 8 digital inputs and 8 digital outputs onboard, plus FLK connector access to the I/Os.

24 VDC inputs (logic "1" 13-30 VDC, ~5 mA/ch); outputs 500 mA per channel, 4 A per module, 2 A per group, short-circuit/overload protected; response ≥1 ms typical.

INTERBUS local/remote bus 500 kbps via 9-pin D-SUB; ST local bus connector; expandable with up to four INTERBUS-ST I/O modules.

It serves as compact digital node on an INTERBUS fieldbus as spare replacement.
