CONNECTION DIAGRAM

A supply voltage must be applied to terminals A1 and A2 (for AC supplies) or terminals B1 and B2 (for DC supplies). Once the supply voltage is applied, 24V DC is available at terminal T11; power LED illuminates. Terminals T12, K21 and K22 must be connected according to the application example selected to meet the application requirements. Feedback monitoring of external devices is accomplished by a connection between terminals T34 / X1 and X2. If the application does not require external monitoring, T34 / X1 and X2 must be bridged. To start the unit, terminal T11 and T34 / X1 must be bridged (automatic reset) or a momentary bridging of T11 and T34 / X1 must take place. With all of the above in place safety contacts 13-14, 23-24 and 77-78 close. Channel 1 (K2 energized) and channel 2 (K3 energized) green LEDs illuminate to show channel status. Fault LED illuminates when a short circuit takes place, at the input stage or internally.

(*) Special edition with hard gold-plated contacts is also available. Connecting the ground wire to PE - see page 22.
