Notes) 1. When using contact input, since current ?ow is small from terminals 1 and 3 on the panel mounting type and terminals e to t and S to F on the PC board
mounting type, please use relays and switches with high contact reliability.
2. When using transistor input, use the following as a guide for which transistors (Tr) to use for inputting. (Collector withstand voltage Q 50 V, leakage current < 1 μA)

Notes) 1. 2 and 4 . (The input and reset circuits are functionally insulated.)
2. When using transistor (Tr) input, use the right as a guide. (Collector withstand voltage Q 50 V, leakage current < 1 μA)
3. Be aware that the application of voltage that exceeds the voltage range of the H level to the count input terminal, and the application of voltage to the reset input
terminal, can cause damage to the internal elements.
