3RK1408-8KG00-0AA2 AS-INTERFACE SLIMLINE MODULE
From SIEMENS
| AS-i ground fault module IP20 S22.5, ground fault monitoring 1 input, remote reset 2 x signaling output, Relay DC-12 1 A / DC-13 500 mA (24 V) Spring-type terminal Overall width 22.5 mm No AS-i address required Only AS-Interface monitoring | |||
| General technical data: | |||
| Design of the product | ground-fault detection modules - modules with special functions | ||
| Product function | |||
| Ground fault detection | Yes | ||
| counter | No | ||
| Overvoltage detection | No | ||
| Protocol is supported AS-interface protocol | Yes | ||
| Type of electrical connection of the inputs and outputs | spring-loaded terminals | ||
| AS interface total current input max | mA | 40 | |
| Earth fault | 10% Uas-i <= Ugnd <= 90% Uas-i | ||
| Addressing | the module does not need its own AS-Interface address | ||
| Signal range | |||
| low signal lin max | mA | 1.5 | |
| high signal | |||
| — Uin min | V | 10 | |
| — lin min | mA | 6 | |
| Current carrying capacity | |||
| DC-12 | A | 1 | |
| DC-13 | |||
| — 24 V | mA | 500 | |
| — 48 V | mA | 200 | |
| Operating cycles DC-12 | 2 000 000 | ||
| Rated operational voltage DC | V | 24 ... 48 | |
| Rated temperature | °C | 25 | |
| AS interface Connection Polarity reversal protection | built-in | ||
| Note 1 | If repeaters are used, a ground fault detection module must be used for each AS-Interface segment (number of AS-Interface power supply units = number of ground fault detection modules) | ||
| Note 2 | Uaux should be protected by a 2 A slow fuse. The endurance of the relay can be increased if inductive loads are connected using freewheel diodes. | ||
