Weidmuller 8543820000 analogue DC current/voltage signal converter with integrated limit-value monitoring and external power supply. The input and output parameters can be configured. During operation, the analogue value on the input side is continuously monitored. The upper and lower operating points can be adjusted and are switched via relays. Various monitoring functions such as fail-safe, non fail-safe, high/low trip and hysteresis can be adjusted via DIP switches. The WAS5 DC/Alarm is constructed with 3 Way isolation. The 24V DC supply voltage can be bridged using pluggable ZQV 2.5N cross-connectors on the module side. The monitoring components can be used anywhere within the electrical cabinet or in process and industrial automation applications.
