• Astro - Optional Astro feature is assignable to any combination of channels. Astro will auto-
matically keep track of the changing sunrise and sunset times throughout the year without
the need of a photocell. The Astro feature will keep assigned output(s) off during daylight
hours.

intended for use with latching relays. An EL74 configured as momentary will only have 2
channels. Relay 1 will provide a 1 second ON pulse for Channel 1. Relay 2 will provide a 1
second OFF pulse for Channel 1. Relay 3 will provide a 1 second ON pulse for Channel 2.
Relay 4 will provide a 1 second OFF pulse for Channel 2. See example 2 on page 43 for
