What the ratings actually mean for fit
The QY81P: Short-circuit proof: each output is fuse-protected, and a blown fuse lights an LED per point. That saves troubleshooting time on the line — you see the dead output instantly without a meter.

Mitsubishi MELSEC Q series, QY81P digital output module, 32 transistor source outputs at 0.1 A, short-circuit proof with fused LED indication, 12/24 V DC.

The QY81P: Short-circuit proof: each output is fuse-protected, and a blown fuse lights an LED per point. That saves troubleshooting time on the line — you see the dead output instantly without a meter.
Each output is short-circuit proof via an internal Zener diode and fuse; a blown fuse triggers an LED per point for immediate identification.
No. The QY81P uses a 37-pin D-Sub connector and Mitsubishi Q backplane; the 2D-TZ535-EIP is an Allen-Bradley Point I/O module with a different form factor and connector. Full rewiring and a different base required.
