Table 2-3 External input/output specifications
<Caution>
• In the group with the multiple Lossnay units, input the signals to the main Lossnay (with address number 1 or
the smallest number other than 0).
(Note 1) The input signal must conform to the following specifications:
Level signal Volt-free contact, 12 V DC, 24 V DC
Pulse signal Volt-free contact, 12 V DC, 24 V DC, the duration of ON and OFF should be 200 msec.
or more
In the case of relay contact input, use a relay having a contact rating of 15 V DC/0.1 A or higher and a
minimum applicable load of 1 mA or less.
(Note 2) Check the specifications of the external device.
(Note 3) In the group with the multiple Lossnay units, make sure that:
• Connect the signal cables only to the main Lossnay unit when controlling the all Lossnay units
together using PZ-62DR-E.
• Connect the signal cables to each Lossnay unit when controlling the Lossnay units individually with-
out using PZ-62DR-E.
(Note 4) In the group with the multiple Lossnay units, input the signal only to the main Lossnay unit (with
address number 1 or the smallest number other than 0).
