ABB Electrical 1SDA054897R1 SACE Tmax Motor Operator

Model Type: MOE-E T4-T5 220...250 Electrical 1SDA054897R1 SACE Tmax Motor Operator

Features and benefits

Termination for up to sixteen (16) analog I/O process signals within a horizontal row.

All SD I/O modules & bases of all types (Singular or Redundant) AND (Compact or Full-size), are 100% fully compatible with each other. 

Thus, Singular & Redundant, Compact or Full-size I/O modules can be mounted within a single, common HN800 I/O bus.

Optional mechanical keying can be implemented to prevent insertion of the wrong I/O module type.

Latching device on the base locks the base into position on DIN-Rail.

Industry standard 35-mm DIN rail, Horizontal row mounting.

Furthermore, the anti-pumping device only allows circuit-breaker closure if the following conditions 

are present at the same time:

 1. Closing spring fully charged

 2. Opening mechanical pushbutton and/or opening release coils (-MO1/-MO2) are not active.

 3. The circuit breaker is in the Open position.

Below is a side internal view of the EL mechanism and the associated anti-pumping component. 

When the opening pushbutton or coils are activated the opening shaft lever pushes down on point C of the anti-pump device.

This causes the device to side down slot D in direction of arrow B. 

Then the trigger portion A moves out from between the closing push-button and the closing shaft lever. 

So if the closing button or signal is held active and the opening button or signal is then activated.

The trigger A will pull out from between closing shaft lever and the closing push button. 

Once the open signal is released the trigger A will come to rest under the closing push-button and will 

not return between the closing shaft lever and closing push-button until the button or closing command is released.

The closing push button is operated by the closing coil (MC) directly by the shaft closing device.

This allows the anti-pumping device to prohibit closing by manual or electrical means.
