Feedback about revised version of Batrium - ExpansionBoard

Before the next fabrication of the ExpansionBoard we are looking to revise the module to give it more options.Theexisting 4 FET digital outputs have been upgraded to handle 65V4A instead ofeither 12V4A or 65V 1.5A. In additionreducing the mechanical relays from 4 to 2 can give room toadopt SSR (solid state relays) that are more durable (relayshave a finite number of switching i.e.10000)

We plan to adopt Option A, but before we fabricate lets see if there are any reasons that this does not make sense.

Option A

• 2 x mechanical relays
• 2 x SSR 50V2A (solid state relays)
• 2 x FET 65V4A (negative switched)
• 2 x FET 65V4A (positive switched)
• unchanged -2 x reserveddigital output, 6xdigitalinput ,2 x0-5Vanalog input, neopixel

Option B

• 2 x SSR 250V4A (solid state relays)
• 2 x SSR 50V2A (solid state relays)
• 2 x FET 65V4A (negative switched)
• 2 x FET 65V4A (positive switched)x SSR 250V4A, 2 x SSR 50A 2A, 2 x FET 65V4A (neg), 2 x FET 65V4A (pos)
• unchanged -2 x reserveddigital output, 6xdigitalinput ,2 x0-5Vanalog input, neopixel

Original

• 4 x mechanical relays
• 4 x FET outputspositive switched (either 12V 4A or 48V1.5A)
• unchanged -2 x reserveddigital output, 6x digital input , 2 x 0-5V analog input, neopixel

In general, I appreciate the FET voltage upgrade very much. For me Option A) is ok but Option B) is also interesting (250V driving capability). What would be the price difference between Option A and Option B?
When will this improved version be available?

Ideally thesame price
