What are the differences between ABR-1 and ABR-2 electromechanical zelio interface modules?

ABR-1 electromechanical interface modules are supplied in the form of compact modules, 17.5 mm/0.689 in.wide.
They are designed for interfacing discrete digital control signals exchanged within an automated system between the processing unit (PLC, numerical controller, etc) and the other components (contactors, solenoid valves, indicator lamps, proximity sensors, etc)
These products are based on contactor technology and are notable for their excellent adaptation to industrial environments,
conforming to the recent IEC 947-5-1 standards.

The ABR-1 range comprises into 2 families:
Input interfaces
Input interfaces switch input signals to the processor and are characterized by their high contact degree of contact reliability:
Less than 1 fault per 100 million operating cycles at 17V, 5mA
The interfaces can directly control most contactors and indicator lamps because of the high switching level characteristics.
Output interfaces
Output interfaces control the preactuators (contactors, solenoid valves, etc) for signaling devices (indicators lamps, audible alerts, etc). They are characterized by a high switching capacity with an average durability of up to 5 times greater than the traditional interface modules
which include standard relays.
 
 

ABR-2 electromechanical interface modules complement the ABR-1 range.
They are characterised by micro relay technology which allows reduced dimensions and low switching levels (TTL, HCMOS, analog signals).
The ABR-2 family is in the form of slim compact modules, 9.5 mm/0.37 in. wide for input interface modules, 12 mm/0.47 in. wide for output interface modules, and 17.5 mm/0.69 in. wide for low level switching products.
 
The ABR-2 range comprises into 3 families:
Input interfaces (9.5 mm/0.37 in. pitch)
Input interfaces switch input signals to a processor and are characterized by their their high contact degree of contact reliability:
Less than 1 fault per 100 million operating cycles at 17V, 5mA
An immunity to current leakages ≤ 2 mA, and a wide coil voltage range (0.7 to 1.25 Un).
 
Output interfaces (12 mm/0.47 in. pitch)
Output interfaces control the preactuators (contactors, solenoid valves, etc) for signaling devices (indicators lamps, audible alerts, etc). They are characterized by a high switching capacity and immunity to current leakages y 2 mA. A lower cost version without LED signaling is available.
Low level switching input and output interfaces (17.5 mm/0.69 in. pitch) with 1 C/O contact
These interfaces are designed for switching logic (TTL or HCMOS) and analogue signals.
 
Warning Never switch inductive loads with this type of interface
