Programmed Firmware Chip for AS3141KT

F3141 standard and customised pre-programmed microcontroller firmware chips only for use in our Multi-Mode Universal Delay Timer kit AS3141KT which is now available in a pre-assembled version without any firmware (see Order Code AS3141-HP-NF below). They can also be used to upgrade your existing 3141 board or incorporated into your own custom hardware design.

The "Special Mode 0" versions have the standard 3141 Modes 1-7 plus an extra Mode 0 (all mode selection switches off).

Please see User Manual for full explanation of the 7 standard timing modes.

• F3141-M0v1GW (Customer Specific Mode 0): split Factor switch for different pulse pause times
• F3141-M0v2: Mode 0 is similar to standard Mode 3 but the trigger signal logic is reversed. While trigger signal is present timer is inactive. Loss of the trigger signal starts the countdown delay. Relay turns on at the end of the delay time. Restoration of the trigger signal at any point resets the timer and deactivates relay if active. Useful for a delayed activation output when a control signal drops out e.g. warning buzzer, etc.
• F3141-M0v3: Mode 0 is similar to standard Mode 4 but timer is non-retriggerable. Relay activates on trigger and any further trigger inputs are ignored. Relay releases on timout and timer resets

We will fit firmware of your choice into the AS3141-HP-NF board if both are ordered together.
