Why Choose the ABB 1SAH100530R9900 PLC-Controlled Mini Contactor Relay?
The ABB 1SAH100530R9900, also designated MCRI040ATD, is a compact four-pole mini contactor relay designed for switching control signals and small loads in industrial automation, machinery and building-control systems. Its low-consumption DC coil enables direct control from a compatible programmable logic controller.
This contactor relay incorporates four normally open auxiliary contacts and screw terminals for straightforward control-panel wiring. Its space-efficient construction delivers dependable switching performance where installation space is limited.
With a 24 V DC control coil consuming 1.2 W, the MCRI040ATD is suitable for direct PLC operation without an intermediate coupling relay where the PLC output has the required capacity. It supports AC-15 control loads up to 6 A at 240 V AC and can be installed on a DIN rail or mounting surface.
Key Advantages
- Low-consumption 1.2 W coil supports direct PLC control.
- Four normally open contacts for flexible signal switching.
- Compact four-pole construction saves control-panel space.
- 24 V DC control voltage suits industrial automation systems.
- Screw terminals simplify installation and maintenance.
- Suitable for DIN-rail or wall mounting.
Key Features
- ABB MCRI mini contactor relay series.
- 4NO auxiliary-contact configuration.
- 24 V DC PLC-compatible control coil.
- Coil holding and pull-in consumption of 1.2 W.
- 6 A AC-15 rating at 240 V AC.
- Rated auxiliary-circuit voltage of 690 V AC and 440 V DC.
- Standard screw-terminal connections.
- IP20 terminal protection.
Efficient Direct Control from PLC Outputs
A mini contactor relay uses an electromagnetic coil to change the state of its auxiliary contacts. The low-power coil in the ABB MCRI040ATD allows a compatible 24 V DC PLC output to operate the relay directly, helping reduce the need for intermediate coupling components.
The four normally open contacts can distribute control signals, operate auxiliary loads or provide interlocking within an automation system. Compact dimensions and flexible mounting make the relay suitable for densely populated control panels and machine-control assemblies.
Typical Applications
- Direct switching from compatible PLC outputs.
- Industrial machinery control circuits.
- Electrical-panel relay logic and interlocking.
- Automation and process-control systems.
- Building-control and HVAC equipment.
- OEM machinery and compact control assemblies.
