What is the internal load resistance of pulse input?

You specify it for current pulse input. The resistance you specify depends on the specifications of the transmitter (mainly the rated current of the open collector). The internal load resistances are 200 Ω, 500 Ω, and 1 kΩ, and 0.5 W and 2 W are available based on the transmitter power supply specifications. (The VJP8 is externally attached. Comes with an external resistance of 200 Ω, 0.5 W. Consult with Yokogawa for other resistances.)
