Introduction

Properties of the OSM ITP53
Electrical ports	5 x 10/100 Mbps
	autonegotiation/autocrossover ports
	ITP connectors (sub-D 9-pin female)

Optical ports	3 x 100 Mbps FO ports (full duplex)
	BFOC female connectors
Maximum distance between two OSMs	3000 m

Maximum ring span with 50 OSMs	150 km
Digital Inputs	8 x DC 24V

Note

Industrial Ethernet OSM ITP53 is available in two versions:

•OSM ITP53 with eight digital inputs:

The eight digital inputs are connected over two plug-in 6-pin terminal blocks on the top of the device. To display the status of these inputs using the eight device LEDs, there is an additional display mode known as the "Input Status" that is selected using a third mode LED.

•OSM ITP53 without digital inputs:

There are no digital inputs and the "Input Status" display mode is not available. The operating states are displayed by two mode LEDs.
