Figure 5. ACS control element — normally open relay contact
Figure 6. ACS control element — circuit with open-collector output
The relays PASS A (contacts PASS A and Common), PASS B (contacts PASS B and
Common), Ready (contacts Ready and Common), Detector (contacts Det Out and
Common) and Alarm (contacts Alarm 1 and Alarm 2) have normally open contacts. The
"Common" contact, at that, is not connected to the CLB power supply negative terminal.
In the initial (inactive) state, when the power is on, the relay contacts "PASS A", "PASS B",
"Ready" and "Detector" are closed (voltage is supplied to the relay coil) and the "Alarm"
relay contacts are broken (voltage is not supplied to the relay coil).
The CLB relay operation/release is indicated by lighting up/going down of the red test
indicators located near the corresponding relays (Fig. 4).
The output cascades for PASS A, PASS B, Ready, Det Out and Alarm are the contacts
with the following signal characteristics (Fig. 7):
maximum commutation voltage...................................................................... 42V DC
maximum switched current................................................................................ 0.25A
closed contact resistance ...................................................... no more than 0.15 Ohm
