Either one or two rear ports (RS485 or fibre optic) are provided for connection to a remote PC and
for IEC60870-5-103 communication with a substation control and automation system. Further,
Ethernet LAN port can be provided as option.
Further, the GRZ100 provides the following functions.
- Configurable binary inputs and outputs
- Programmable logic for I/O configuration, alarms, indications, recording, etc.
- Automatic supervision
The GRZ100 has the following models:
