Resistor type (Azbil Corporation's PGM_ _ 2A1, etc.)
When necessary, an appropriate external resistor is connected in series so that the
voltage between the input terminals of the SSR you are using is within the specified
range.

V: 19 V ± 15%
R0: 82 Ω ± 0.5%
R1: 680 Ω
R2: 260 Ω
Vf: 1.1 V
Voltage between terminals of PGM = (V - 2 × Vf) / (R0 + R1+ R2 + R2) × R2 + Vf
=
4.5 V
Input voltage range of PGM: Since the input voltage range is 3 to 6 V, the
operation is possible.
