Timers
Timers for Industrial Automation and Control
Timers are control devices used to delay, measure, or repeat operations in machines and processes that rely on timed events. In industrial automation they work alongside relays, contactors and PLCs to start or stop outputs after a set time, measure how long equipment has been running or count down to a process step.
Preset timers are configured for a specific time interval and then provide an output when that interval has elapsed, making them useful for controlling batch durations, cycling equipment, dwell times, alarm delays, and other fixed timing functions. Elapsed time indicators record and display the total run time of a motor, machine, or process to support maintenance scheduling, usage tracking, and diagnostics. Multifunction counter-timers combine counting and timing modes in one device for applications that need both event counts and timed control.
Galco offers timers for panel and DIN-rail mounting, including preset timers, elapsed time indicators, and multifunction counter-timers, so designers and maintenance teams can match timing range, mode, display, and mounting style to each application.
Frequently Asked Questions
How do I decide what timing range I need?
Select the timing range based on the longest time delay required for your application. If the exact interval is not known, choose a timer with a wide timing range or adjustable settings so you can fine-tune it in the field.
Can timers replace basic PLC timing functions?
In some cases, yes. A standalone timer can handle simple delays or cycles without requiring PLC programming. This is useful when only a small timing task is needed and using a PLC would be unnecessary or more costly.
What should I consider when choosing a timer for inductive loads?
Inductive loads such as motors or solenoids can cause voltage spikes across relay contacts. Choose a timer with relay contacts rated for inductive switching or use external suppression devices to protect the contacts.
