Input: 24 (Twido) vs 24 (M221)
Relay Output: 14 (Twido) vs 16 (M221)
Trans Output: 2 source (Twido) vs 0 (M221)
Analog Input: 0 (Twido) vs 2 (M221)
Power supply: 240VAC (Twido) vs 240VAC (M221)

Software Compatibility:
- SoMachine Basic Software could convert an application of Twido to M221 (except the function like Asi & CanOpen not supported by the M221)

Mechanical Compatibility:
- Same Width 70 mm & same Depth (Height) 90mm
- The M221Length is higher due to TB in 5.08 mm pitch vs TB in 3.81mm pitch on Twido
- M221 can support TM2 Digital & Analog IO module
- All module & accessory TWD*** are not supported by M221 in particular CanOpen, Asi, Serial Interface & display module.
- Twido + CanOpen Module = M241 CanOpen
- Twido + Asi Module = M221 Eth + Eth/Asi Gateway
