Description of MTL TP48-3-N-NDI Surge Protection Devices MTL TP48-3-N-NDI Safeguards Electronic Process Transmitters
 
The TP48 range of surge protection devices uniquely provide a level of protection for 2, 3 and 4 wire field-mounted transmitters that is far in excess of the optional transient protection facilities available from the transmitter manufacturers - without involving any additional wiring,conduit modifications or other expensive extras.
 
The TP48 range protection network consists of high-power, solidstate electronics and a gas-filled discharge tube capable of diverting 20kA impulses. The whole unit is encased in a 316 stainless steel housing, threaded for the common conduit entries used on process transmitters. Versions are available for 1/2” NPT, 20mm ISO, and
G1/2” (BSP 1/2 inch) threaded entries.
 
Installation can easily be carried out retrospectively to existing installations. The TP48 is screwed into any unused conduit entry on the transmitter case and flying leads are connected to the terminal block (+ve, -ve) and the internal earth stud. The 3 wire TP protects +ve, -ve and signal. The 4 wire TP48 protects +ve, -ve, signal +ve and -ve. The TPs operate without in any way affecting normal operation - passing acor dc signals without attenuation while diverting surge currents safely to earth and clamping output voltages to specific levels.
