The TLP Accessories complement the surge protection range by providing remote panel indicators and a built-in Modbus interface module. These accessories enable easy status monitoring, remote signalling, and seamless integration with control and automation systems, enhancing the functionality and management of TLP surge protectors.

TLP-DSI – designed for TLP connection
The TLP-DSI is a self-powered remotely mounting status indicator which mirrors the status LEDs on Transtech’s High Energy TLP’s which have a unique remote Indicator (Code RI) output fitted.
The LEDs of the TLP-DSI match their respective status LED on the monitored TLP unit. A unique circuit design means that only 3 wires are required to display the status of any one of the monitored TLP LEDs.
The length of the 3 core cable between the TLP-xxx and its TLP-DSI should be no more than a maximum of 5 meters.

TLP-PSI – designed to retro-fit any relay output
The TLP-PSI is a 48mm x 48mm AC or DC powered, status indicator which may be connected to any Transtech model TLP product which incorporates a status output relay. The TLP-PSI can be mounted in a convenient location at some distance from the associated transient protection device.
The TLP-PSI uses a transformer isolated 24V DC to monitor the TLP status (fault) relay, it has three status LEDs;
BLUE: Power supply OK
RED: Protector is healthy
YELLOW: Protector is faulty (replace)
