The 497 series digital timer then acts like a pre-set (or pre-determined) counter.
FEATURES:
• Panel mounted
• Covers available
• 3 & 5 digit models
• Minutes & seconds models
• Auto-reset versions
• M5 & 4mm push-on models

There are 2 displays. One is the pre-set, which is input using the push buttons on the front. The second display shows time elapsed, all seconds or all minutes according to model. When time elapsed matches the pre-set value, the normally closed internal valve switches to open, and a continuous pneumatic output is achieved. Re-set is either manual by push button, or by a pneumatic pulse to port Y. 2 models are available with automatic re-set.
