Janitza RCM 201-ROGO

$1.00

The Janitza RCM 201-ROGO is used for standard compliant type A measurement on DIN rails in conjunction with the RCM 202-AB to enable continuous monitoring of TN-S systems and comply with DIN EN 62020/VDE 0663/IEC 62020.  This refers to residual current monitoring devices which check circuits for the occurrence of a residual
current and trigger an alarm if a set alarm value is exceeded.The Janitza RCM 202-AB is employed with current transformers connected for the measurement and monitoring of residual currents of the types A, B and B+ in TN and TT systems (grounded AC systems).

Features include:

  • Very high levels of accuracy
  • Retrofittable
  • Seamless compatability with Janitza RCM devices
  • Standards Compliant to IEC62020
  • Alarm Function
  • RS485 (Modbus RTU) and all Janitza Modbus master devices
