Remote release for time exposures compatible with Mamiya 645 Pro TL?

[Ralphieboy]

Does anyone know if such a device exists? I have the electro release cable for my Pro TL but I've not figured out how to get long, 2-5 minute, exposures without watching a timer and releasing the cable button, which ain't real accurate.

I've tweaked your thread title, and deleted your duplicate thread.
You are essentially looking for a remote release with a built in intervalometer, that can be set for single, long exposures in bulb mode.
In case you are not aware, adapters are available for your camera that permit use of mechanical cable releases, so if you have one of those cable releases that are set up to control long time exposures, you can use them.

And in case it helps with your search, electronic releases for the RZ67 are compatible with the 645 Pro and Pro TL.

Thanks! I looked for a way to delete the duplicate but didn't find it.

I have the type A electro-magnetic cable release, but it relies on either a 4 second shutter on the camera or my watch timer for longer shutter sequence. I'm looking for something I can set for an extended period of time leaving me free to 'multi-task' with my other cameras.

In that case, I'd look "old school" - find a mechanical option, that uses the mechanical cable release connection on either the RC402 or RA402 - I use either one of them when I decide to use a cable release.
You might find someone who has reverse engineered the electro-mechanical connection to permit use of non-Mamiya remote controls - I would guess that would be more likely in the RZ67 community.

Not equipment related, I have been using the Jiffy Night exposure since it was first published in 1963. It is my go to guide for available light night photography.
