AS-Interface: Slaves (continued)
Modules with special functions
Counter module
Counter modules
• Degree of protection IP20
• For evaluation of pulses
• Connection with screw terminals or spring-type terminals
Your advantage: Evaluation of pulses which exceed even the clock frequency
of AS-Interface.

Ground-fault detection
module
Ground-fault detection modules
• Degree of protection IP20
• Display using LEDs
• Two signaling outputs
Your advantage: Automatic diagnostics of ground faults on AS-Interface

Overvoltage protection
module
Overvoltage protection module
• Degree of protection IP67
• Discharge through ground cable with oil-proof outer sheath
• Protection at transition of lightning protection zones
Your advantage: The AS-Interface overvoltage protection module protects downstream
AS-Interface devices or individual sections in AS-Interface networks from conducted
overvoltages.

SIRIUS 3RA2712 function
module for AS-Interface
SIRIUS 3RA27 function modules for AS-Interface
• Connection of 3RT20 power contactors with communication capability, 3RA23 reversing
contactor assemblies, and 3RA24 contactor assemblies for star-delta (wye-delta) starting
to AS-Interface
• Reduction of control current wiring through plug-in design and integrated monitoring
of circuit breaker/motor starter protector and contactor
•
Reduced space requirement in the control cabinet through fewer digital inputs and outputs
in the control system
• Easy configuration through operation of feeders instead of individual contactors
• Enhanced operational reliability and quick wiring thanks to spring-type connections
• Small number of variants through use of identical modules for size S00 to S3 contactors
Your advantage: Shortening of mounting and startup times.

3RA61 compact starter
Motor starters for operation in the control cabinet
SIRIUS 3RA6 compact starters
3RA61 direct-on-line starters, 3RA62 reversing starters
• Degree of protection IP20
• Very compact load feeders with the integrated functionality of an electronic overload relay
• As direct-on line or reversing starters for motors up to 15 kW/400 V
• Easy expansion into a communication-capable load feeder using AS-i add-on modules
• On-site safe disconnection also possible using AS-i add-on modules
• Standardized integration of the loads in higher-level control systems using AS-i
Your advantage: Compact solution with minimum wiring outlay for actuating direct-on-line
and reversing starters in the control cabinet.
