Industrial and process environments are particularly prone to dangerous and damaging transients and surges which can be coupled and induced onto signal lines as a result of lightning and power switching.Such surges and transients often cause erroneous equipment operation, corruption of process controllers and program data, resulting in system failure and unexpected downtime.
The CRITEC UTB uses a hybrid, three stage clamping circuit, to ensure the best possible protection to sensitive electronic equipment, while maintaining a minimum of line interference and insertion losses.
The UTB Series is designed to provide transient protection for equipment from surges induced onto balanced pair signal lines. They are well suited to the protection of industrial equipment such as PLCs and SCADA systems. Other uses include the protection of fire and security alarms, industrial monitoring and control equipment.
The UTB-SP (single pair) employs a hybrid multistage clamping circuit, to help ensure the best possible protection to sensitive electronic equipment while maintaining a minimum of line interference and insertion loss.
The UTB-DP (dual pair) employs a hybrid, multi-stage clamping circuit to help ensure the best possible protection to sensitive electronic equipment while maintaining a minimum of line interference and insertion losses.
The UTB-DPS (dual pair – single power supply, single data pair) is specifically designed for applications where compact protection is required for one signal pair and one power supply, common in powered transducer applications. The UTB-DPS combines both these protection circuits in one compact package.
The UTB-TA and UTB-SA are specifically designed to protect telephone/modem circuits.
