The closest functional peer in the same A Series family is the A16-30-01-80. Both share the 16A frame and 3-pole main contact layout, but the AF16 carries the universal coil (100-250V 50/60Hz-DC) while the A16-30-01-80 uses a fixed 80V coil. If your control circuit runs at 110V or 220V, the AF16 is the drop-in; the 80V coil needs a separate transformer or a different supply rail.
Snap-on DIN rail mount, standard 45mm width per the A Series footprint. The 100-250V coil draws from the control transformer tap — no extra DC power supply needed if your panel already has a 24V bus, but verify the coil's DC rating covers your actual bus voltage (100-250V DC means it works on 125V or 220V DC buses, not 24V). Wire the coil across the control voltage terminals; the integrated coil suppression handles the back-EMF on DC switching. Auxiliary contact configuration is 30-10-13 (3 N.O. main + 1 N.O. + 1 N.C. aux) — enough for a holding circuit and a status feedback to the PLC.
