3RK1105-1BE04-4CA0

What type of automation component is this?

It is an ASIsafe enhanced safety monitor for AS-Interface and AS-i Safety at Work systems. It is designed to monitor protective devices such as emergency stop circuits and provide monitored enabling outputs within an industrial control system.

What is the main function of this safety monitor?

Its main function is to evaluate safety-related signals on an AS-Interface network and control safe output circuits. It includes two enabling circuits and can control one safe AS-i output or safe coupling arrangement.

How many enabling circuits does it have?

The unit has two enabling circuits. These allow it to handle two release circuits for safety-related control functions in suitable AS-i Safety at Work applications.

What type of terminals does it use?

The device uses removable screw-type terminals for the inputs and outputs. This makes it suitable for panel wiring where secure, serviceable terminal connections are required.

What is the maximum response time of the safe output relay?

The safe output relay has a maximum response time of 40 ms. This figure is important when assessing the total reaction time of the wider machine control system.

What safety performance levels can this device be used for?

When correctly integrated into a suitable system, 3RK1105-1BE04-4CA0 can be used up to Category 4 according to EN 954-1, up to PL e according to EN ISO 13849-1, and up to SIL 3 according to IEC 61508.

What is the ingress protection rating?

The device is rated IP20. It is intended for installation inside an appropriate control cabinet or enclosure rather than direct exposure to harsh plant-floor conditions.

What mounting options are suitable for this unit?

The unit is designed for screw mounting or standard rail mounting. This makes it suitable for typical control panel layouts where DIN rail or fixed mounting arrangements are used.

What are the approximate physical dimensions?

The listed dimensions are approximately 45 mm wide, 108 mm high and 120 mm deep. These dimensions help when planning space inside an electrical cabinet.

What operating temperature range is specified?

The operating temperature range is specified as -20 °C to +60 °C. Storage temperature is listed as -30 °C to +70 °C.

What rated operational currents are specified for the relay outputs?

The rated operational current is 3 A for AC-12 at 250 V, 3 A for AC-15 at 115 V and 230 V, and 3 A for DC-12 at 24 V. For DC-13, it is rated at 1 A at 24 V, 0.1 A at 115 V and 0.05 A at 230 V.

What kind of AS-i system is it intended for?

It is intended for AS-Interface and AS-i Safety at Work installations. The monitor is used to evaluate safety-related AS-i devices and manage safe output behaviour within the configured safety system.

Does it include an integrated safe slave?

Yes. The unit includes an integrated safe slave, which forms part of its ASIsafe enhanced safety monitor functionality.

What does Monitor Type 6, Version 3 refer to?

Monitor Type 6, Version 3 identifies the functional version of this AS-i safety monitor. This is relevant when matching the unit to an existing AS-i Safety at Work configuration.

What is the typical weight of the unit?

The listed weight for 3RK1105-1BE04-4CA0 is approximately 0.400 kg, making it a compact panel-mounted automation component.
