How it stacks against its 32-point sibling
The CP1W-32ET provides 32 solid-state outputs with screw terminals; the CRT1-OD16SY provides 16 NPN outputs in an ECON package. Different output count and termination style prevent a direct swap.
Active and mature, so no imminent last-time buy. The part is quoted to order; lead time varies by quantity but the supply path is open. No official successor has been issued — this is the current production variant for the CRT1 series output modules.
