Basler Electric 9170206111 – Protective Relay Module for Auxiliary Control

The Basler Electric 9170206111 is a compact protective relay module intended for auxiliary tripping, alarm annunciation, and logic interlocking in generator excitation and protection panels. This unit interfaces with main protection relays, providing additional output contacts and signal isolation to enhance system reliability and flexibility.

Design and Functionality

The module accepts a wide range of DC voltage inputs (24–240 V DC) and provides multiple isolated Form‑C output contacts that can be used to drive circuit breakers, alarm buzzers, or remote indication devices. Its solid‑state design ensures fast operation, typically within 5 ms, while the galvanic isolation between input and output prevents ground loops and transient interference. The 9170206111 is often employed as a buffer stage between sensitive electronic relays and heavy inductive loads.

• Input voltage: 24–240 V DC (wide range)

• Output contacts: 4 Form‑C relays, rated 5 A at 250 V AC / 30 V DC

• Operate time: < 5 ms (typical)

• Isolation voltage: 2500 V RMS between input and output

• Indicators: LED for power and each output status

• Mounting: DIN‑rail or panel mount

• Operating temperature: –25 °C to +65 °C

Application Areas

This relay module is commonly found in generator control cubicles, where it expands the trip output capability of main protection relays such as BE1‑32R or BE1‑67N. It also serves as an alarm repeater, sending signals to a central control room or DCS. In retrofit projects, the 9170206111 can replace older electromechanical auxiliary relays, offering higher speed and longer life.

Installation and Maintenance

The unit is supplied with pluggable terminal blocks for easy wiring. Mounting on DIN rail or with screws allows flexible placement within the panel. Diagnostic LEDs provide real‑time status, and a manual override pushbutton is available for testing purposes. No regular calibration is required; periodic inspection of connections and cleanliness is sufficient to maintain reliable operation.

Quality and Support

Built to Basler’s stringent standards, the 9170206111 undergoes rigorous testing for dielectric strength, impulse withstand, and thermal cycling. It is compatible with all Basler BE1 and SSR series devices, ensuring seamless integration. The module’s compact size and robust construction make it a dependable choice for auxiliary protection duties.

In conclusion, the Basler Electric 9170206111 protective relay module is an essential accessory for expanding control capabilities, providing secure isolation and extra contacts for critical tripping and alarm circuits.
