Phoenix Contact has revolutionised surge protection devices for Measurement and Control Technology (MCR) and extra low voltage applications with the release of its TERMITRAB Complete Range. (TTC)
TTC provides you with a complete Surge Protection system kit for your MCR signals, featuring an integrated status indicator and a unique optional “optical” remote signalling set.
The new range features the world’s narrowest surge protection solution. At just 3.5mm wide, this device is ultra slim and compact. By using leading-edge components in this 3.5mm SPD, you can now build smaller systems to protect both analogue and digital signals and gain valuable installation space for system planning, and of course, save money in the process.
Also, the 3.5mm devices provide the highest SPD density for system expansion on the Din-rail, so you can quickly and easily expand your systems to protect up to 572 MCR signals per metre.
The 3.5mm TTC SPD is available as a push-in model, while the big brother 6.2mm TTC SPD’s provide maximum protection, features and considerable choice.
You can choose from versions with screw or push-in Terminals, knife disconnections, pluggable or non-pluggable, direct or isolated Earthing or Ex approval, to meet any specific application requirements.
No auxiliary power needed
The 6.2mm TTC models also feature an integrated status indicator that shows when the SPD has reached its end of life and requires replacing. Better still, the indicator on the surge protection device does not require any auxiliary power. The integrated thermal disconnect feature, ensures safe behavior in the event of an overload, and the measuring signal is completely unaffected ensuring the ongoing reliability of the MCR system.
You can also choose to install the optional, unique, Remote Signalling Set to remotely detect any TTC SPD’s that require replacing and maintain the integrity of the system.
The Remote Signalling Set is easy to retrofit and does not require any programming or additional wiring to the TTC SPD’s. The Transmitter and Receiver in the Set use a non-mechanical and non-electrical photoelectric barrier to monitor the status of up to 40 adjacent TTC devices and a floating relay contact transmits the status to the PLC, BMS or Control Room.
Let’s talk about reliability
TERMITRAB Complete range delivers outstanding reliability and durability. To ensure each device is robust and can perform exactly as specified, the arresters undergo thorough testing in Phoenix Contact’s accredited test lab, whilst every TTC device undergoes complete testing on the Production Line before being shipped.
The comprehensive tests include surge current tests, vibration and temperature tests as well as salt spray and corrosive gas testing. The TTC SPD’s meet SIL 3 and IEC 61508.
For additional peace of mind – by allowing a complete SPD Maintenance program, all Phoenix Contact pluggable surge protective devices can be tested with the Phoenix Contact mobile test lab, the “Check Master 2”.
More than 130 models and more being added
The TERMITRAB Complete range has over 130 models including the ultra-narrow 3.5mm, to simple single-stage 6mm surge protection units, right through to multi-stage devices with all the options.
The extensive range is suitable for 12, 24 and 48V Analogue and Digital signals including high current 6A models. As well as 2, 3 and now 4 wire RTD measurement, data and communications up to 90Mbps and Ex rated devices, and new models are being added every few months.
The latest 4 wire floating signal TTC SPD brings 4 protected signals to an SPD only 6.2mm wide. Perfect for weighing and temperature signals in the smallest possible space.
The portfolio of TERMITRAB Complete arresters is ideal for use in process technology, wind power, water and wastewater treatment, building services and infrastructure.
