Nearest equivalent to CAL32E000

The CAL32E000 is 1/32Din size controller, that works from a 100-240VAC supply. It has an SSR Driver output (nominal 5VDC) and a relay.

The CAL32E000 is still available to purchase, as is the CAL3200000 which is identical except for the display which is green instead of West.

The CAL32E00 could also be replaced by a more modern CAL or West brand product:
The closest functional replacement is the CAL33000000C. Like the CAL32E000 this is also 1/32Din size controller, that works from a 100-240VAC supply. It has an SSR Driver output (nominal 5VDC) and a relay. It also has identical operating menus etc, so they can set it up easily. Only the connections are different, and the terminal block does not unplug.
The West N2300-2101could be used, as this is also a 1/32Din size controller that works from a 100-240VAC supply. It has an SSR Driver output (nominal 10VDC) and a relay. However, its operating menus are different to the CAL products, so it will be a little more difficult to set up, even though it can do the same job. The connections are also different, and the terminal block does not unplug.
