Voltage Range Nominal Voltage Power Frequency
100–132 V AC 110 V AC 6 VA 47-63 Hz
200–264 V AC 240 V AC 6 VA 47-63 Hz
21.6–26.4 V DC* 24 V DC 6 W (at 24 V DC) -
*The 4 V DC rated model has cULus approval. File number E56486.
Digitalpulseoutput
The retransmit pulse output gives a single pulse every time the total
increases by one unit. The pulse width is a constant  ms and the
minimum off time is  ms. The output is an isolated, NPN, open
collector transistor type and can switch a maximum of 50 V DC or a
current up to 00 mA.
Resetpulseinput
Accepts a volt-free contact closure, or a shorting link, between pins
 and 1. The contact must be closed for at least 100 mS.
