F7553 | Hima Coupling module

in the assembly kit B 9302, with switch-off of the watchdog signal, for PES H51qLED WD on the front plate shows the existing fail-safe watchdog signal. By the second LED SEL the access to the IO modules of the appertaining IO subrack is signalled. Via the shrouded switch WD the WD signal can be switched off to change the coupling module F 7553 without releasing a system emergency-off.The coupling module consists of the monitoring of the 5 V supply of the IOsubrack and transmits a corresponding status signal to the central module.The module is automatically tested during operation.Space requirement 4 TEOperating data 5 V DC: 600 mA24 V DC: 750 mA
