Guard Locking with Time-Delay (GLT) Safety Relay User Manual
literature.rockwellautomation.comThe GLT is a Guard Locking with Time-delay safety relay. This safety relay is designed to use time-delayed outputs for use in Stop Category 1 and to unlock a safety gate when the time expires. It also provides a lock command to lock a safety gate before the starting of the hazard.

Chapter 7 TIMERS, COUNTERS and T/C APPLICATIONS
www.eng.utoledo.eduthe main function of all timers, a time delay. While PLC vendors do not need to use the terms of on-delay or off-delay, normally closed, normally open, held closed, or held open, these terms are an important part of design of PLC circuits. Some vendors still use the terms to show linkage between the PLC and the original timer circuits.

Technical Explanation for Timers and Time Switches
www.ia.omron.comWith ON-delay operation, the Timer receives an input and then an output signal is output by switching the Timer contacts after a set time delay. This name is used because there is a delay between when the input signal is received (i.e., turns ON) and when the output signal is output. ON-delay operation is the oper ating mode most often used for
Power System Protection - Philadelphia University
www.philadelphia.edu.joTime-overcurrent relays (ANSI 51 relays) have two basic settings: the pickup current and the time delay settings. The process for determining the time delay setting involves: (1) Calculation of a time delay value in definite-time overcurrent elements (2) Selection in inverse-time overcurrent elements of a time-current curve from a family of curves.
