GRIDlink can extend to the DR Event signal to other parts of the plant or building by using the ET-8DI2-8DO2 industrial remote I/O Module.
The module includes 8 Digital inputs for counters to accept KYZ pulses or can indicate a motor is running or accept a contact to opt out remotely.
Also included are 8 Digital Outputs for load shedding. These can be programmed in the GRIDlink for special control strategies.
The communications can be:
Modbus RTU RS485 wired over shielded twisted pair which has a distance of up to 1200m
Modbus TCP CAT5E using CAT5e cable has a distance of up to 300m.
Modbus TCP can be further expanded from 1500m up to 5000m using GRIDlink WiFi. The WiFi Client can connect to your existing secure 802.11 a,b,g,n or with the GRIDlink WiFi Access Point operate on a dedicated robust WiFi network and achieve greater distances.
GRIDlink uses an advanced Industrial POE radio with built in antenna. It is weatherproof and operates in extreme environments -30 to +75C.
Easy to install since it requires only a single CAT5E cable for connectivity and power. Simply strap it in place in line of sight of the Access Point and plug it into the POE injector provided. A second cable goes from the injectorto the EtherTRAK Remote IO module. A carrier class outdoor Ethernet cable is provided per customer requirement.
