Modicon AS-J890-101 Remote Processor ASJ890101 Schneider Electric PLC

At power-up, the I/O modules perform an extended self-test for about 30 seconds. If these tests are unsuccessful, the modules are not considered to be healthy and do not start. The inputs and outputs are then set to 0.

If the 24 VDC external power supply is not connected to the digital input or digital output modules, the power-up self-tests do not take place and the modules do not start.

During runtime, the I/O modules perform self-tests. The input modules verify that they are able to read data from the sensors over the complete range. The output modules perform pulse tests on their switches with a duration lower than 1 ms.

Because the electronics may not work up to the theoretical maximum output voltage of the power supplies, the I/O modules must supervise the backplane power supply voltage.

Before tightening the locknut to the torque 0.50...0.80 Nm, be sure to properly position the right-angle F adapter connector.
