VCL-TP, Teleprotection Equipment with Trip Counter Display
VCL-TP, Teleprotection Equipment is an extremely reliable and flexible product that offers up to 8, 2- way independent command channels which can be operated selectively or simultaneously over a wide choice and a variety of transmission interfaces.
The VCL-TP, Teleprotection Equipment offers a choice of transmission interfaces which include the IEEE C37.94; IP/MPLS; G.703 E1, 2.048Mbps and G.703 64Kbps co-directional digital data interface options.
VCL-TP, Teleprotection Equipment may be used independently, in a standalone point-to-point application over C37.94 or IP/MPLS links, or as an integrated part of the VCL-MX Version 6, E1 Voice and Data Multiplexer solution over SDH / PDH E1 networks.
The “Trip Counter Display” shows the total number of “Trip Input / Trip Receive” and “Trip Output / Trip Send” commands on each of the 8 Teleprotection channels, individually. A manual display counter reset option is also provided which may be enabled or disabled by the system administrator.
Trip Counter Display and Alarm Extension Unit is designed as an optional extension of the Teleprotection Equipment to provide 8 Channel, Digital Trip Counter Display along with 8 External Relay Alarm outputs.
The Trip Counter Display and Alarm Extension Unit may be either powered from the Teleprotection Equipment, or directly from a 48V DC, 110V DC, 220V DC or 250V DC power source. 1+1 Redundant Power is also offered as an option.
