What is the ABB 81AR01A-E used for?

The 81AR01A-E is a relay output module designed for the PROCONTROL P14 system. It is primarily used for activating the triggering actuators of protection equipment, particularly in connection with the 83SR04-E/R1411 module. It supports safety disconnection operations such as 2-out-of-3 voting configurations.

How many output channels does the 81AR01A-E provide?

The module provides 8 relay output channels (function units 1-8), plus an additional master disconnect relay (K9) that can simultaneously disconnect all eight outputs.

What type of relays are used in this module?

The module contains type-tested relays with positively driven contacts. This design ensures reliable disconnection operations, making the module suitable for safety-critical applications such as protection system tripping.

What is the difference between R0100 and R0200 versions?

R0100 (GJR2397800R0100): For actuators operating on single positive voltage
R0200 (GJR2397800R0200): For actuators requiring two voltages (positive and negative)
The R0100 version features single-pole fusing, while the R0200 version has twin-pole fusing.

What is the output current rating?

The module is rated for 24V DC at 30 mA per channel.
