Product Description:

The 0G1000.00-090 is a protective terminal accessory produced by B&R Automation within the 0TG Terminal Guards series. It mounts over field connectors to shield conductors and complete network termination in distributed I/O stations. The cover also reduces accidental contact with active terminations during service work inside harsh industrial control enclosures. That role helps maintain stable data exchange on serial bus networks used in automated machinery.

This guard presents a DSUB shell with a male header, so it plugs directly into an existing device port. Inside the housing, all 9 contacts route to screw clamps, which support quick jumper changes and convenient access during signal checks. That arrangement keeps individual conductors accessible without removing the entire connector shell. Communication follows the balanced RS485 standard, helping preserve signal integrity over long cable runs and across multiple devices on a shared line.

An internal link bar bonds the shield to chassis ground and applies the proper electrical load. This helps maintain predictable loading at the end of segments. The unit handles 2 bus lines, and wiring lands on screw clamp terminal blocks for secure lead retention in vibrating equipment. The terminating resistor is switchable by slide lever, and compatibility with PROFIBUS DP nodes allows use at segment ends or mid-span taps without protocol changes.
