ABB AD01A Multi Input Module 16-CH

The EL operating mechanism of the Advac circuit breakers (in all versions) is fitted with a mechanical anti-pumping 

device which prevents re-closing due to either electrical or mechanical commands. 

Should both the closing command and any one of the opening commands (local or remote) be active at the same time, 

there would be a continuous succession of opening and closing operations.

The anti-pumping device avoids this situation, ensuring that each closing operation is only followed 

by a single opening operation and that there is no closing operation after this. 

To obtain a further closing operation, the closing command must be released and then re-launched.

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.

The SD (Symphony DIN) Series is a green portfolio of completely scalable control 

and I/O products that work in any environment or geographic location,

Through seamless interconnections with smart field and electrical devices and higher level applications, 

these rugged control and I/O products deliver lower energy consumption, 

an extreme operating temperature range, and a scalable architecture in a compact, modular footprint, 

making SD Series the best automation solution for your new installation, upgrade or expansion. 

Powerful, scalable controller family for high-end (SPC800/HPC800), mid-range (SPC700)

and small (SPC600/SPC700) applications from discrete and continuous,

to batch and advanced control applications.

Simultaneous support for SD Series, HR Series and S800 I/O subsystems.

SD Series controllers communicate with S+ Operations, S+ Engineering and other higher level applications via a high-speed,

high-throughput, and high-security Fast Ethernet-based redundant plant network.

Environmental management 

OT-switches are manufactured at the Finish plant, 

which has been certified according to ISO 14001 since 1997 

(the plant has been also certified according to the ISO 9001 quality management standard since 1993). 

Life cycle assessment is applied continuously to all product development.

The HBR01-CJC the mounting base is for RAI04, Redundant, 16-CH, TC & mV analog input modules. 

The base includes a built-in RTD that can be used for Cold Junction Compensation.

Two (2) 16-point headers on the base provide connections to either (2) pluggable 

16-point terminal blocks for direct connection of field signal wires or to SPK0x_-yy marshaling 

cables when field signal wires are landed on 3rd party termination hardware.

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.
