ATX400 - Safety Circuit Module

ATX400 safety circuit module provides monitoring of parametric safety circuit, which status reflects to output contacts of the module. Monitored safety circuit consists of 2 current loops ended with terminators based on ATX302 circuit. The construction of the module allows it to be used to separate intrinsically safe and nonintrinsically safe circuit. To provide appropriate intrinsically safe feature the module should be placed inside a casing with at least Ip54 protection degree or in a flameproof casing. ATX400 module is produced in version for supply voltage 12 V (ATX400/12) and in version for supply voltage 15 V (ATX400/15).
