PSR-...- 24DC/SSM/2X1
102759_02_en PHOENIX CONTACT 5
Function
If the 24 V DC operating voltage is applied at terminal
blocks A1 and A2, the electronics checks (in the stop state)
whether at least one of the proximity switches provides a
signal at input IN1 or IN2.
The FO diagnostic output indicates the ready state with
+24 V. The "Power" and "Mode" LEDs light up. If this is the
case (one or both proximity switches provide a signal), the
internal output relays switch to the operated condition. N/O
contacts 13-14 and 23-24 are closed, N/C contacts 31-32
and 41-42 are open, and the "Output" lights up. Alarm
output MO indicates +24 V.
The outputs remain active in their switch position as long as
no signal change is generated at inputs IN1 and IN2 by a
movement.
N/O contacts 13-14 and 23-24 open and N/C contacts
31-32 and 41-42 close if a signal change with a frequency
> 2.5 Hz is detected at inputs IN1 and IN2. Alarm output MO
is a high-resistance output.
If the input circuit frequency is less than 2 Hz (stop state
entered or movement not hazardous), relays K1 and K2
switch. N/O contacts 13-14 and 23-24 are closed and N/C
contacts 31-32 and 41-42 are open. Alarm output MO
indicates +24 V.
In the event of an error (sensor error), the "Mode" LED
flashes and FO is a high-resistance output.
For a connection example, please refer to page 6.
Assembly and Startup
In order to comply with UL approval, use copper cables that are designed for operating temperatures > 75°C.
For reliable and safe-to-touch contacts, strip the cable ends as follows:
